RS-232 Channel Transmission
You can connect an RS-232 serial device to the RS-232 port on the units for RS-232 bypass
channel, such as a touchscreen or a barcode scanner. The RS-232 signal transmission flow can
be illustrated as follows:
Receiver
PIN
CONFIGURATION
(Captive screw
connectors)
The general concept here is that an RS-232 signal can be transmitted (Tx) to the receiving (Rx)
end of a unit. The received signal can then be transmitted (Tx) to the receiving (Rx) end of
another unit. The RS-232 signals can be transmitted back the other way.
