System Configuration Examples
When SECS Is Used
Communications with the host device is possible using the SECS protocol.
With the above system configuration, the Amplifier Unit connected directly to the CIDRW Controller
converts signals from RS-232C to RS-485. If this Amplifier Unit is removed, communications will not be
possible with the other Amplifier Units. If the Amplifier Unit connected directly to the CIDRW Controller
must be removed while the system is operating, insert a Link Unit (V700-L11) between the CIDRW
Controller and the first Amplifier Unit. If an Amplifier Unit on the end of the network is removed, be sure
Host
The CIDRW Heads are the

writing the carrier IDs.
The Amplifier Units con-
trol the CIDRW Heads.
Up to 31 Units can be
connected.
This is a host computer,
equipment controller, etc.
