1. Introduction
The TRP-C07 repeater boosts the RS-422/485 signals to extend the distance up to 4000 ft
(1200M) and increase the maximum number of connected nodes up to 128. With data format
auto detecting and baud rate auto switching function TRP-C07 is able to automatically detect the
data flow and switch the direction of the data lines accordingly as well as to automatically
configure RS-422/485 signals to any baud rate without external switch setting. The optical
isolation provides 3000VDC of isolation to protect the host computer from ground loops and
destructive voltage spikes on the RS422/485 data lines. The internal surge-protection on each
data line protects the module from dangerous voltages.
