3–8 Installation and Wiring
Connecting the Communication
Cable to the Module
Follow these steps to connect your module.
1. Verify that the cable/connector is correctly wired (See Figure
3.5).
2. Locate the D-shell connector at the base of the RS1 Module.
3. Plug cable/connector into the RS1 D-shell connector and secure.

Chapter 4
Modes of Operation
Chapter 4 contains the following information:
•Powering up the drive with the RS1 Module installed.
•The modes of operation and LED indications.
Powering Up the Drive After you have installed the RS1 Module, apply power to the drive
and to the connected device. The READY LED should illuminate. If
it does not, refer to Chapter 9, Troubleshooting.
LED Indicators The RS1 Module has three LEDs (see figure below) which provide
module status.
The LEDs are defined as follows:
• COMM – The COMM LED has four possible states:
Green (solid) The cable is connected (both ends) and module is ready to
communicate.
Green (flashing) The module is on-line and communicating.
Red (solid) Connection was lost or application timed out.
Red (flashing) Device is transmitting & receiving data but application has timed out.
•FAULT– This LED tracks the fault status of the 160 Drive.
When no faults are present, the LED will be off. The LED will
illuminate (red) if a drive fault occurs.
• READY – The Ready LED will illuminate (green) whenever the
module is connected to the drive and power is applied.

4–2 Modes of Operation
Modes of Operation The RS1 Module has three modes of operation.
•Power-up mode
•Run mode
•Error mode
Power-up Mode
The following sequence of operation occurs:
1. During power-up, the READY LED illuminates.
2. The module reads and stores the DIP switch settings.
If the power-up sequence is successful, the module enters the run
mode and the COMM LED flashes green or turns solid green.
If the power-up sequence fails, the COMM LED will go to solid red
and the module will enter the Error Mode. See the Error Mode
description in this section.
Run Mode
After a successful power-up, the RS1 Module enters the run mode
and operates as a slave device to a master device. In run mode, the
module:
•Accepts and responds to messages from the master on the
network.
•Monitors cable integrity.
If an error is detected, the module enters error mode (see below).
Error Mode
If the module detects an error, the COMM LED flashes red or turns
solid red. Refer to Chapter 9 for details on how to recover from an
error.
