About the Serial Port
Your cash register includes 4 serial ports. You can connect items to the
cash register using these serial ports. You can connect the receipt printer,
a PC, an optional barcode reader, or a secondary/backup (KP) printer.
The receipt printer connects to the serial port labeled RECEIPT
PRINTER. To use the optional barcode reader, connect it to the serial
port labeled SCANNER. You can use the serial port labeled PC to
connect the cash register to a PC to use the RegisterLink software. To use
a KP printer, connect it to the port labeled KP.
To connect your computer to the serial port, you need a specific
null-modem serial cable. A 6 foot null modem serial cable is included in
the box with the cash register to use with a PC. If it is lost or damaged,
contact Royal for a replacement.
The pin description for all serial ports on the cash register is shown below.
