Yes, the RobotPOS Plus range has the option of three internal plug-in modules for serial ports and digital cashdrawers.
- Option 1 – Four serial port version
- Option 2 – Six serial port version
- Option 3 – Four serial ports and two auto sensing (12V or 24V) cashdrawer ports.
When deciding how many COM ports are required, bear in mind that COM1 is nomally reserved for the internal optional customer display (if required) but COM 1 can also be used externally by changing jumpers internally. COM2 is used internally for the touch controller and is not available externally. COM3/4/5/6 are free and can be configured for 5V or 12V by changing jumpers on the serial port module.
