Industrial CONTROLS Instruction Manual
●INTRODUCTION:
The equipment described in this instruction manual is manufactured and/or distributed by Reliance Electric Industrial Company.
The Isolation Short Haul Modem is intended for asynchronous transmission of data over distances up to 10 miles at a rate up to 19200 baud. It may be used in simplex, half duplex or full duplex systems, allowing local communication between computers, monitors, printers, or any device equipped with an RS-232/CCITT V.24 interface.
The Isolation Short Haul Modem also provides isolation for the communications ports on the DCS 5000 Processor Module (M/N 57C407), and the Communication Interface Modules (M/N 57C414, 57C417, 57C418, and 57C428). Isolation is required when the connected device is located at a cable length greater than 10 feet from the DCS module or the device communications ground is tied to earth ground. Two Isolation Short Haul Modems are required per application.
