AEOS Blue units can easily be connected to each other using the 485bus. This document supplies detailed information about cabling, the 485bus, and describes how to proceed when existing cabling is used or when an isolated bus is needed. The preferred bus isolators are also described. The AEOS Blue power supply 12V can supply several AEOS Blue units with power. Detailed information about this power supply is given in this document. You will also find additional information about the input and output signals, as well as an explanation of the information you can find on the different AEOS Blue product labels, including the dot code.

AEOS Blue cabling and technical aspects
1.
Cable options
Different cable types can be applied on AEOS Blue devices:
Cable specifications Type Shielded Unshielded Shielded Unshielded Shielded Unshielded
Conductor size 22 AWG 0.33 mm² 22 AWG 0.33 mm² 24 AWG 0.20 mm² 24 AWG 0.20 mm² 26 AWG 0.13 mm² 26 AWG 0.13 mm²
Maximum cable length (twisted pair) R (Ohm/km) 53 53 84 84 135 135
485 bus 1200 m 150 m 1200 m 150 m 600 m 150 m
RS485 reader 1000 m 50 m 1000 m 50 m 600 m 50 m
Preferred: 22 AWG and 24 AWG, shielded, R < 117 Ohm/km.
1.1.
Non-preferred cables
Commonly used cables as CAT5, CAT5E and CAT6 are allowed, if compliant to: Characteristic impedance: 100-120 Ohm Mutual capacitance: max. 65nF/km Total DC series loop resistance: max. 234 Ohm/km (2 x cable length: up to the end and back) Twisted pair wires Shielding (cable screen) is highly recommended. So use cable types: F/xTP, S/xTP, SF/xTP ../xTP U or F (UTP or FTP), example: CAT5E F/UTP cable F/.. Foil shielding (outer layer only) S/.. Braided shielding (outer layer only) CAT cabling is available in different specifications. The diameter of the used wires is important: Unshielded cables and/or AWG 26 cable sizes are not according to the AEOS Blue cabling specifications. They would reduce the maximum cable length. See also the attention points in chapter 1.2.
1.2.
Attention points when using non-preferred cables
1.2.1.
Power
Thinner wires cause more voltage drop. This can result in too low voltage at the AP7003 or the readers. Preferable: use 24V (27VDC) power, this results in a wider voltage range for the AP7003 and the readers. In case of any doubt, always measure the voltage at the AP7003 and the connected readers, with maximum power consumption. Use multiple wire pairs for feeding power: o One twisted pair for the 485bus communication o Other pairs in parallel for power: Put all white-colored wires in parallel and also all colored wires (this results in a twisted pair wire, also for power and GND). o Pay attention to the maximum specified current per conductor. If possible, feed the door locks with an external (local) power supply and not with the bus cable. 1.2.2.
Guarantee
Nedap cannot guarantee that any installation will function properly under all circumstances. For example, Nedap does not guarantee that installations where unshielded cables are used in combination with a lot of disturbance around them (heavy machinery) will function properly. Of course Nedap has included many fault protection mechanisms in the 485bus protocol, but problems could still arise, especially with long and unshielded cables. 1.2.3.
Certifications
If other than the recommended cables are used, the certifications can become invalid. Certifications are validated with the recommended cables, as stated in chapter 2.1.

AEOS Blue cabling and technical aspects 1.2.4.
Bitrate
In case of malfunction of the 485bus communication, a switch to a lower bitrate can be useful. The default bitrate is 240kbps. By applying the BitrateControl AEbc, other (lower) bitrates can be selected.
2.
Cable types
2.1.
Recommended cabling
The following table shows the recommended cable types for each type of connection for AEOS Blue:
Wiring
Type
Characteristic impedance (Ohm)
485bus 485bus communication 1 x 2 x 0.22 mm² shielded Power 2 x 0.5 mm² shielded Reader wiring (depending on reader) RS485 excl. power 1 x 2 x 0.22 mm² shielded RS485 incl. power 2 x 2 x 0.22 mm² shielded Wiegand n x 0.22 mm² shielded Inputs / Outputs (depending on peripheral) Sensors n x 0.22 mm² shielded Outputs n x 0.5 mm² shielded
Max. length
100-120 n/a
1200 m 5m
100-120 100-120 n/a
1000 m 150 m 150 m
n/a n/a
100 m 100 m
The stated wire diameter is the minimum diameter. Remark: The use of thicker wires is allowed without having influence on the certifications. However, these cables must still be tightened with the strain relieves, to make a correct shielding connection between the cable shield and GND. Remark: Always check if the voltage at the end of the cable is sufficient. Especially long, thin wires can cause a significant power loss.
3.
PoE
If PoE/PoE+ is used on the AP7803, no power is supplied on the 485bus at the AP7803. The first AP7000 following the AP7803 on the bus must have its own power supply. This power supply can be used to feed the following AP7000s in the bus. Vin 1 2

4.
The AEOS Blue Installation guides present all connections and cable specifications: One AP7803 (master) can handle up to 31 AP7000s (slaves), using the 485bus at max. 1200 meters. The 485bus is non-isolated. When AP7000s are used in different buildings, there can be a difference in potential between GNDs. In those cases, a suitable RS485 bus isolator must be used to isolate the bus. An alternative solution could be adding an AP7803 to the other building, which will split up the 485bus.

4.3.
Bus isolators
To apply an isolated bus, bus isolators should be placed where the 485bus goes into and out of the building. You always need a pair of bus isolators. Specifications for the bus isolators are: Baudrate: up to 240 kbps EOL resistor: 120 Ohm Power supply: 10-30VDC (feed with Vin) Nedap recommends the following bus isolators: ADAM-4510s from supplier Distrelec (or Advantech). Settings: DIP Switch: SW1 10 bits (default SW2 115.2 kbps (ADAM accepts 240 kbps) Jumper: CN3 1-2 short (120 Ohm) CN5 1-2 short (120 Ohm) Remark: Nedap doesn't supply these bus isolators.

AP7021 Power Supply
5.1.
Output voltage check
The AP7021 is a 12VDC power supply, but adjusted to 13.2V (voltage adjuster on power supply). In case of doubt, measure the output voltage of the AP7021 and adjust it to 13.2V. In case long and/or thin wires are used and power is supplied over this cable. Always check the available voltage at the end of the cable.
5.2.
Power capacity
The power supply in the AP7021 is labelled by the manufacturer as 12VDC, 6A. However, the certifications applied on this power supply are valid for max. 4.5A. This 4.5A value is the correct value to use with AEOS Blue.

AEOS Blue common input and output signals
Each module has its own specific inputs and outputs. The inputs can be related to the external hardware (e.g. IN1, ExtTamp) or can be an internal signal that is generated by the processor for indication purposes (e.g. Vlock, IntTamp).
6.1.
Commonly used inputs for all modules
The basic setup is the same for all AEOS Blue modules. As a result, there is a list of commonly used signals that can be found on all modules: Name IntTamp

AEOS Blue cabling and technical aspects 6.2.
Power input: Vin - Vraw
The devices are powered at the Power connector (Vin – GND). Vin is internally called Vraw. All output voltages are derived from Vraw and will follow Vraw with regard to its voltage. As additional electronics are used to check and control the output voltages, the output voltages will always be 0,7V lower than Vraw (depending on current drawn). The module will measure Vraw and can disable the derived voltage outputs (e.g. Vlock and Vreader) if necessary, e.g. for safe power-up.

Connect to InputGuard InputGuard BitRateControl
Power output: Vlock and Vreader
The voltages at Vlock and Vreader follow the input voltage (Vin). Both are independently controlled by the microprocessor: A digital monitoring signal representing their activity is available as a digital signal (Vlock, Vreader) During power up, to gain a controlled start-up Maximum current detection and protection Short circuit detection and protection Vreader has reverse current protection (applying external voltage to Vreader will not influence Vraw) Most firmware will power-down Vreader during a reset In case of irregularities, the power outputs are disabled, where Vreader will go down first (lowest priority) and, if necessary, Vlock will follow (higher priority).
7.2.
Power output with PoE on AP7803: Vlock and Vreader
When using PoE+ of PoE at the AP7803 the Vlock and Vreader act differently: Voltage is 12V fixed (do not connect Vin) When using PoE+, current available for Vlock and Vread. When using PoE (13W), current available for Vreader only. Vreader still fully protected. Vlock is also available, but when used, short/overcurrent protection will not work correctly for both Vreader and Vlock. So do not use Vlock in combination with PoE!

Power output: Vaux, Vout1 and Vout2
Vaux, Vout1 and Vout2 follow the input voltage (Vin). All are independently controlled by the microprocessor: A analogue monitoring signal (ThresholdGuard) for each voltage representing their actual value is available During power up, to gain a controlled start-up Maximum current detection and protection Short circuit detection and protection Over-voltage detection Vaux has reverse current protection (applying external voltage to Vaux will not influence Vraw) Most firmware will power-down Vaux during a reset. In case of irregularities, the power outputs are disabled, where Vaux will go down first (lowest priority) and, if necessary, Vout1 and Vout2 will follow (same higher priority).
8.2.
Serial interface (auxiliary communication channel)
The serial interface can be set to RS485 or RS232. This can be achieved by a property setting at the applied AEbc. Its default setting is RS485. Baudrate is also set by the AEbc and is hardware limited to 250KBaud.
9.
AEOS Blue digital and secured digital inputs
Inputs on AEOS Blue modules can be available as: Secured digital inputs Statuses: Open, Closed, Sabotage Open, Sabotage Closed Masking (availability of Masking depends on the AEbc that is connected to the input). Sabotage can be activated in AEbc by activating the checkbox Input x Sabotage alarm enabled, Masking only at specific AEbcs. The most commonly used inputs on the Blue modules are secured digital inputs. Digital inputs Statuses: Open, Closed Inputs as AC Ok, Batt Low, ExtTamp are digital inputs. Note: Check the installation manual to see which type is applied on a specific input. If the additional statuses at secured digital inputs are intended to be used, the correct Resistor network (double loop principle) on the external device must be available. Default resistor values are 4K7 Ohm, for other values and using the Masking function the Detectors AEbc must be applied. With this AEbc, the different resistor values can be programmed.
