RS-232 Pass-through Configuration
The Pass-thru Control port on the rear panel of the encoder (see figure 6 ,
R
on
page 13), or decoder (see figure 7 ,
R
on page 13) is used for RS-232 pass-through
communications, allowing a control device connected to one VNM 250 unit (the server) to
control remote devices connected to other VNM 250 units (clients).
Serial data received by one VNM 250 unit is transmitted over the network, using
TCP/IP, and then converted back to serial data at the target VNM 250 unit. Data flow is fully
bidirectional.
Units that are configured for this type of data flow are called pass-through groups (see
RS-232 Pass-through on page 19).
