Product Introduction:

1.Description

MO-D210 is used for the communication between the CCUs and to the IPU in a CIS. It is Connected directly to the COM boards of the CCU using the own 12V power supply via RS232 connection. It can also work as standalone with separate power supply.

MO-D210 is used in pairs, a transceiver is connected to each COM cards of a CCU. The distances the transceiver can be used is between 1m and 40km,but for shorter distances than 100m an attenuator has to be used.
