RS-232 Channel Transmission
You can manage the VE2812R / VE2812PR via RS-232 serial devices, such as
computers or bar code scanners. The RS-232 signal transmission flow can be
illustrated as follows:
From a source device, the RS-232 signal is transmitted (Tx) to the VE2812R /
VE2812PR receiving (Rx) unit; the a compatible ATEN Video Receiver
transmits (Tx) signals to the display device (Rx).
You can set the VE2812R / VE2812PR to either bypass serial data or to receive
RS-232 commands. By default, the VE2812R / VE2812PR is set to bypass
serial data. To set the unit to receive RS-232 commands, press the Input Switch
pushbutton for 5 seconds. For details on RS-232 commands, see
