RSB001 RS422 Interface Board
4Pages

Product data Features • Single-ended to differential RS422 • Small size, easy to connect • Connectors for flexibility or soldered flat cables for minimum profile height The RS422 Interface Board converts 5V TTL or CMOS single-ended encoder signals to RS422 differential signals. The ASSIST Interface Board and the ASSIST software allow to configure and/or program the encoder. Encoder Power The three ways to power the encoder are explained below. Encoder power from RS422: put the Encoder Power jumper in place. Do not connect the ASSIST Board. Encoder power from ASSIST Board: remove the Encoder Power jumper. The RS422 power supply may be connected or not. Configure the encoder using the ASSIST Board, then switch to RS422 power: 1) Remove the Encoder Power Jumper 2) Connect the RS422 connections, including supply pin 1 (Fig 3) 3) Connect the ASSIST Board 4) Start the ASSIST software and configure the encoder 5) In the ASSIST software go to the evaluation window and start the encoder (the encoder is now powered by the ASSIST Board) 6) Put the Encoder Power jumper in place (the encoder is now powered by two sources with the same voltage) 7) Disconnect the ASSIST Board connector (the encoder is now powered by the RS422 supply voltage) Fig 2 RS422 Board (1) connected to ASSIST Interface Board (2), which is connected via USB cable (3) to a PC with ASSIST software. The inputs (4) are singleended and the outputs (5) are RS422 differential. In/outputs The input signals may be on different pins of the Encoder connector and are selected in Table 1. Connectors The board can be ordered with or without connectors according to Table 3. If ordered without connectors, the cables can be soldered directly to the board, resulting in a low profile-height.
