TP6000 USER’S MANUAL 4 - 2
Serial Port – COM1
CAUTION: The COM1 serial port should be occupied by either a suitable serial
device or a COM1 terminator at all times (as supplied). Without this provision the
cash drawer control ports will fail to work correctly.
The recommended devices for COM1 are either an external customer display
or a serial POS printer. When such devices are installed to the TP6000 series, please
remove the COM1 terminator and store in a safe place for future use.
Serial Port – COM2/3/4
For models using the RS232 interface touch controller (TP6XXXR), there is
no extra serial port other than COM1 available for system revision A and for models
of system revision B or later COM4 port is not available. For models of system
revision A using the PS2 interface touch controller (TP6XXXP), only COM1 and
COM2 are available. The COM4 has to be connected through a special cable
CCBLA-338. All these ports are standard RS232 serial port with the possibility to
supply a +5 V DC through pin 9 after proper jumper setting change. Any attempt to
break/remove the cover/plug on the forbidden port (COM2 of rev. A or COM4 of rev.
B or later) in TP6XXXR will void the product warranty.
