1. Introduction
TRP-C07 is designed to extend the RS-422 and RS-485 signals to another 4000ft (1200m)
distance and increase the maximum number of connected nodes up to 32 sets. Aside from
extension function TRP-C07 provides with auto configuration features in data format detecting,
baud rate setting and RS-485 data direction flow control. TRP-C07 is equipped with
photo-couplers and internal surge protection to protect the module and all data lines against high
voltage spikes, as well as ground potential differences. The industry standard DIN rail and panel
mounting design enable user a fast and professional installation. TRP-C07 is the ideal solution
for the user who wants to automate their application quickly, safely and cost-effectively.

3. Install TRP-C07
3-1. Connect power source with TRP-C07
The TRP-C07 has a two pins terminal block and power jack. Power can be supplied from
terminal block or external power adapter and supports wide input range from +10~30V. When
power is correctly supplied the PWR LED will lighting and indicate the system is up and running.
It is highly recommended use the power jack specification 5.5*2.1*12mm if the power supply is
from external DC plug.
Warning: User can only choose one of following 2 power sources.
1. External DC adapter. 2. Screw terminal DC input
Do not use both power input simultaneously.
