RS-232 Channel Transmission
You can manage the VE2812UST / VE2812EUT via RS-232 serial devices,
such as computers or bar code scanners. The RS-232 signal transmission flow
can be illustrated as follows (VE2812UST is used as the example):
The general concept here is that a 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.
You can set the VE2812UST / VE2812EUT to either bypass serial data or to
receive RS-232 commands. By default, the VE2812UST / VE2812EUT 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
RS-
232 Commands , page 17.
