Serial Cables & Adapters for WTI Products
1. Introduction This publication describes the serial cables and snap adapters that are used to connect your RSM-8R4 series or MPC series unit to the serial console port on various common devices. For more information on connecting devices, please refer to Section 4 (Hardware Installation) in your User's Guide.
1.1. Straight RJ-45 Cables and Rollover RJ-45 Cables All of the connection examples described in this document include the use either an RJ-45 Straight cable or an RJ-45 Rollover cable. The difference between the two types of cables is the way that the pins in the connectors at each end of the cable are linked to each other. In Straight Cables the pins on each connector are linked to the same pin number on the connector at the other end of the cable; for example, Pin 1 on the right hand connector is linked to Pin 1 on the left hand connector, as shown in Figure 1.1 below. For Rollover Cables, the order of the pins is reversed; Pin 1 on the right hand connector would be linked to Pin 8 on the left hand connector, as shown in Figure 1.2. WTI RJ-45 Straight cables are available in three different models: • RJX-7-15: 15 Feet Long • RJX-7-25: 25 Feet Long • RJX-7-30: 30 Feet Long WTI also offers an RJ-45 Rollover cable: • RJ-ROLL

Introduction
1.2. The RJ-45 Serial Port Interface DCD and DTR hardware lines function as follows: 1.
2.
When connected: a)
If either port is set for Modem Mode, the DTR output at either port reflects the DCD input at the other end.
b)
If neither port is set for Modem Mode, DTR output is held high (active).
When not connected: a)
If the port is set for Modem Mode, upon disconnect DTR output is pulsed for 0.5 seconds and then held high.
b)
If the port is not set for Modem Mode, DTR output is controlled by the DTR Output option (Serial Port Parameters Menu, Option 23). Upon disconnect, Option 23 allows DTR output to be held low, held high, or pulsed for 0.5 seconds and then held high. RJ-45 Pin No.

3. Making Extension Cables This section describes how WTI Snap Adapters and RJ-45 cables can be used to make Extension Cables for connecting to DB-9 ports and DB-25 Ports. This essentially allows you to use your existing Cat 5 RJ-45 cable stock and connectors to make your own, economical alternatives to expensive pre-made cables.
3.1. Null Modem Extension Cable (DTE to DTE) Use a DX9F-DTE-RJ Snap Adapter, a DX9F-NULL-RJ Snap Adapter and an RJ-45 Straight Cable to make a Null Modem Extension Cable (DTE to DTE) as shown in Figures 3.1, 3.2 and 3.3 below: RJ-45
