When SECS is Not Used
Communications with the host device follow the OMRON proprietary protocol.
The Amplifier Units are connected directly to the host device without using a CIDRW Controller.
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
to turn ON the terminating resistance on the Amplifier Unit that will end up on the end of the network
while the Amplifier Unit is removed.
Host
These are antennae for
reading the carrier IDs
from the ID Tags and
writing the carrier IDs.
These are units that
control a CIDRW Head.
Up to 31 units can be
connected.
This is e.g. a host,
or equipment con-
troller.
