Controlling a Modbus RTU Module

Hardware:

A PC with Sealevel DIN rail interface converter (Part# 1104 or 1105) connected to a Modbus RTU Module. The 1104 provides RS-232 to RS-485 conversion and our exclusive autobaud feature that automatically syncs to your data rate and controls the RTS enable/disable signal. The 1105 includes the same features plus 1500 VRMS optical isolation. The 906B module provides 12 digital channels selectable as input or output. Once configured, the device operates as an active RS-485 network slave connected to other modules performing network I/O functions.
