SD-3000 Drive for the ADR-3000 Plus
OVERVIEW The Peek SD Drive fits into the company’s ADR-3000 Plus automatic data recorder, providing a new way to store, retrieve and transport traffic data. It allows an ADR data recorder operator to use standard SD (‘secure digital’) or SDHC (‘secure digital – high capacity’) memory cards. Cards that meet the SD standard use the logo shown in Figure 1. Cards that meet the SD-HC standard, typically those with more than 2GB of capacity, use the logo shown in Figure 2. For SD-HC cards, the drive can use up to 4GB of storage space. Throughout the rest of this document, we will speak of ‘SD’ memory cards when refering to both types.
Figure 1 – SD Logo
Figure 2 – SDHC logo SD memory card technology used by the ADR-3000 Drive module offers highperformance in a reliable, easy to use format. The advantages of SD cards over older memory storage methods include: Write protection for your data Ease of availability Wider range of storage capacities (much higher than PCMCIA) Lower in cost per kilobyte than any other type of memory Easy to use "push-push" socket makes inserting and removing media simple Portability and compact size Interoperable SD cards offer flexibility in transferring data to other devices Can be read from a standard card reader attached to a PC / laptop Allows studies to be created that generate large sized data files (for example, you can use smaller recording intervals on binned files and perform PVR studies simultaneously with a binned study).

Figure 3 – ADR SD Drive System Requirements The Peek ADR SD Drive is designed as a rack-mounted drive for the ADR-3000 Plus rack. The ADR SD Drive has a spring-loaded memory card slot, a status monitor switch, and a pair of status monitor LEDs visible on the front panel. The firmware loaded into the ADR-3000 Plus unit must be at version 6.10 or higher. This allows the host ADR to recognize the SD Drive, and allows an operator to assign file storage to SD cards that have been inserted into the unit.

Installing the Drive The ADR SD Drive itself is not hot swappable. The ADR unit must be OFF when you insert the SD Drive into the ADR rack. However, once the drive is installed into an ADR, the SD memory cards themselves are hot swappable.

Figure 4 – ADR SD Drive installed in an ADR-3000 Plus To install the drive into an ADR-3000 Plus unit, you will first need to remove the power supplied to the unit.
Important
If your ADR-3000 unit is powered using a Peek PMU drive installed in the rack itself, you should be aware that there is a PMU upgrade option that may be required, depending on your exact configuration. The original PMU design provided 250mA of current, which is adequate for most simple ADR3000 configurations. However, if you are using multiple drives in your ADR rack, including those that have significant current requirements such as WIM drives, or multiple sensor drives of any type, you may need to update your PMU to the new configuration. The new configuration is a simple hardware modification of your existing PMU unit, at a minimal cost, that will upgrade the PMU to supply up to 360mA of power. This upgrade is not strictly required to support the ADR SD Drive. However, if you will be using your ADR SD Drive in a fully loaded ADR-3000 unit, we highly recommend that you do request this PMU upgrade.
1.
On an ADR-3000 unit, first disconnect the 12V DC power connected to the rear of the unit. Whether the power is wired directly into the top plug on an ADR Power Management Unit (PMU) in the rack, the default method, or it comes into the unit in some other manner, i.e. from a solar charge controller or from a

cabinet power panel, the power must be removed from the ADR before the new drive is installed. 2.
Remove the Single wide slot cover from the location in the rack where you intend to install the SD Drive.
3.
With no SD Card in the slot of the drive, firmly push the new drive into the ADR rack until it is firmly seated.
4.
Attach the SD Drive to the rack using the top and bottom face screws.
5.
Reattach the power supply to the ADR-3000 Plus unit.
6.
When the Main Menu of the ADR unit shows up on the display screen (or on your attached PC interface), press ESC to enter the menu system.
7.
Press the number 1 on the ADR keypad to enter the Check menu. (Or choose the Check menu option on your PC interface.)
8.
Scroll down the Check menu, and select the Check Equipment screen. 12.288MHz ADR+2/3000 1024K Intel 28F800 V6.10-AS 24-AUG-07 20 BY 4 LCD
Figure 5 – Initial Check Equipment screen 9.
On the Check Equipment screen, press ENTER to go to the next screen. If the SD Drive has been properly installed, the ADR has up-to-date firmware (v6.10 or higher,) and the drive is working correctly, you will see the new file storage location at the bottom of this list. Since there is no SD card installed, it will show the memory location with an unknown (“?”) capacity. FILE STORAGE 604K CPU DRIVE ? SD CARD

10. At this point, insert an SD card into the SD Drive. After a few seconds, the File Storage screen will update to show the capacity of the card. For instance, if you insert a 2GB card in the slot, you will probably see something like this: FILE STORAGE 604K CPU DRIVE 1946M SD CARD
00 08
Figure 7 – File Storage area of the Check Equipment screens – SD Card inserted 11. It is strongly recommended that you format the SD card within the ADR unit before attempting to use it for data storage. This is true even if it came preformatted or you formatted it from a PC prior to installing it in the ADR unit. Formatting is done from the Format Media screen . Use the left and right arrow keys to select SD Drive 08, and press the Enter button to begin the formatting. This completes the installation of the SD Drive.

Using the ADR SD Drive The purpose of the SD Drive is to allow an ADR operator to use standard SD memory cards as a memory storage location for files and data, to allow data to be retrieved from field locations, and to allow files to be transfered between ADR units. Selecting SD Memory Cards The ADR SD drive is compatible with all SD or SD-HC memory cards. This includes any memory cards from your local drug store or local electronics retailer, including larger capacity cards. However the FAT16 filing system used when the ADR SD Drive formats your card will only be able to address the first 4GB of the SD card’s capacity.
Figure 8 – A Typical SD Card Another consideration when selecting your SD memory cards is response time. There are differences in how fast an SD card reads and writes data, which can impact how quickly they read back data for transmission. Generally all SD cards, no matter the make or model, are sufficiently responsive to support the writing requirements of an ADR unit. It should be mentioned, however, that the SD card units sold by Peek Traffic have been specifically selected for their quick response times and for their ability to handle the harsh environmental conditions experienced by a typical roadside traffic counter/classifier. The specifications for the Peek cards are listed on page 12. Inserting an SD Card in the ADR SD Drive The SD Drive’s card slot is a spring loaded mechanism. To insert a card, press firmly until the card clicks into place. The angled notch in the corner of the card should be toward the bottom of the ADR SD drive, and the metal connection pads should be facing to the left. Make sure that the Write switch on the SD card is unlocked.

A card can be inserted into the ADR SD Drive at any time, whether the ADR is powered or not. If power is supplied to the ADR, as soon as an SD card is inserted, the ‘A’ LED will flash momentarily to acknowledge the insertion of the card. But it will then turn off as a power-saving feature.
Figure 9 – Inserting an SD Card into the ADR SD Drive
Formatting an SD Card Formatting an SD Card is performed exactly the same way it is for any other memory location attached to an ADR. Insert the SD card into the slot, activate the ADR interface, and navigate to the Format Media screen. The SD card can be selected by using the left or right arrow buttons, at which point you will see the drive shown like this: SOURCE MEDIA SD CARD 08 FREE MEMORY 01948Mb <>CHG; ENTER SELECTS
Figure 10 – Navigate to the Format Media screen on the ADR It is strongly recommended that you format your SD cards to be used with the ADR within the ADR unit itself before attempting to use it for data storage. This is true even if it came preformatted or you formatted it from a PC prior to installing it in the ADR unit. The reason for this is file capacity. An SD card that was formatted on a PC may only allow 500 individual files to be stored on the card, while the formatting done within the ADR guarantees that the SD card will accept up to 7000 files at once. (Large, complex, long duration studies can easily create large numbers of data files.)

Removing an SD Card from the ADR SD Drive Removing a card from the ADR SD Drive’s slot is a bit more complicated, since it is possible that the ADR could be writing to the card, and you don’t want to interrupt a data-write that may be occuring. To remove the SD card, follow these steps: 1.
Press the SW1 switch on the front of the ADR SD drive to see the current status of the SD card. The A and B LEDs just below the switch will light up to show the current status: Red flashes once to indicate that the card is NOT safe to remove; the card is currently being used to write data. Green flashes twice to indicate that it is safe to remove the card; no data files are open.
2.
If the light flashes GREEN, press the SD card into the slot and release. The card should unclick and come out from the slot a couple of millimeters. Pull the card out.

If the LED flashes RED, you will need to enter the ADR interface and halt the active study, after which you should be able to obtain the double flash of the Green LED. At that point, it will be safe to press the card into the slot, unlatch it from the spring-latch mechanism, and remove it.

Setting the SD Card as an ADR File Location To use the SD card as a file/data storage location, you will need to tell the ADR how to use it. This means assigning files types and percentages to the new memory location provided by the SD card. 1.
Insert an SD card into the ADR SD Drive slot.
2.
Open the ADR interface and press ESC to enter the menus.
3.
Go into the Configure menu (Keyboard button ‘4’ or scroll and ENTER .)
4.
Scroll down and select File Storage. You will see the File Storage selection window. FILE PRIMARY MEDIA BIN CPU MODULE 00< PVR CPU MODULE 00 SETUP CPU MODULE 00
Figure 12 – Setting the SD Card as a file storage location 5.
Move the cursor down to the type of file you want to change to the use of a SD Card. Navigate by using the ENTER key. To select the Primary media for that file type, use the left (F3) or right (F4) arrow keys. This allows the primary media to be changed between CPU MODULE 00 and SD CARD 08. Once SD CARD 08 has been selected, press the E NTER key to move to the screen shown in Figure 13. FILE BIN PVR STP
MEDIA 00 08 00
% 100 100 100
Figure 13 – Defining where files are stored where 6.
Allocate the percentage of memory to be written to the primary media selected in the previous step by using the numbered keys for your selection and pressing the E NTER key to move to the next file type. Once percentages have been entered for each file type, the E NTER key will exit to the previous FILE STORAGE screen.
7.
You can now define a study, and any data generated of the type you specified for it will be stored on the SD Card.

Transferring Files Off of the SD Card To retrieve the data off of an SD card, there are two possible options: Retrieve the Data Remotely This is done in exactly the same manner you currently use, except you choose the source of the data files to be the SD Card. Retrieve the Data Physically The other method to retrieve data from the ADR is to actually travel to the site of the study and to remove the SD card from the ADR SD Drive. Any standard SD Card reader can be used to transfer .bin or .pvr files to a PC or laptop.

ADDITIONAL GUIDANCE For more guidance on the configuration and usage of the SD-3000 Drive, refer to the following documents and contacts.
Troubleshooting These are some suggested steps to follow if your ADR SD Drive is not working as it should. It’s best to work your way from the top to bottom of the table until you find the problem. Table 1 – Troubleshooting checklist Symptom
Possible Causes/Resolutions
Neither A nor B LEDs flash when an SD card is inserted in the slot
Make sure the ADR SD drive is firmly seated in the drive slot. It takes some pressure to properly seat any ADR drive into the backplane of the drive slot. Be sure not to press on the SD card itself if one is inserted in the slot in the drive, as this could damage the slot or the SD card. Power has not been properly restored to the ADR. Make sure the ADR has power by using the interface or some other drive that has LED indicators. Make sure you have a version of the ADR firmware that supports the ADR SD Drive. The firmware should be at version 6.10 or higher. Connections between the ADR backplane boards are not properly seated. Make sure the cables that connect the rear of the engine board to the backplane board are properly attached at both ends. Faulty backplane. Remove the SD Drive and attempt to insert some other ADR drive in the same slot. See if it responds as expected. If not, you may need to return the ADR to Peek Traffic for repair. If another drive placed in the slot works as expected, then it’s like that the ADR SD Drive is faulty. Arrange to return it for repair or replacement. The RMA process is described on the Counter/Classifier Support page on the Peek Traffic website: www.peektraffic.com/ptdataspt.htm
SD Drive doesn’t show up as an option in the ADR screen interface. The check equipment screen shows that the SD Drive is in place, but the card capacity is shown as ‘?’

Make sure you have a version of the ADR firmware that supports the ADR SD Drive. The firmware should be at version 6.10 or higher. The first thing is to verify that the ADR SD Drive itself is working properly. Press the SW1 button and see if one or the other of the LEDs light up. If neither does, then its quite possible the problem is with the drive, rather than the SD card. Use the steps above to check out the problem.

Symptom
Possible Causes/Resolutions Verify that the write-lock mechanism on the side of the SD card is not in the ‘locked’ position. Try a different SD card in the slot and see if a capacity number shows up in the ADR interface. If a card does not work, it may need to be formatted. This can be done using the ADR interface, under the FILES menu. If you cannot get an SD card to be recognized in the slot, even though the drive itself is recognized by the ADR interface, you may have a faulty drive. Arrange to return it for repair or replacement. The RMA process is described on the Counter/Classifier Support page on the Peek Traffic website: www.peektraffic.com/ptdataspt.htm
