If the POS-server cannot be connected to a free COM-port of the POST-terminal, connect it to the POS-terminal's receipts printer port.

To use this connection option, make sure that:

  1. the receipts printer supports the RS-232 standard;
  2. the POS-terminal sends data to the printer in text format.

Use Y-cable to connect the POS-server to the receipts printer.

 Unplug all devices from the mains prior to connecting the POS-server to the POS-terminal serial ports.  Failing to do so may cause severe damage to the hardware.
