APPENDIX E
There are a myriad of PC-based systems out there which do not appear on the AVE Cash Register Compatibility List.
Most of the PC-based cash registers that are not included in the AVE Cash Register Compatibility List are able to
interface to the RegCom-Pro. To find the compatibility of a cash register we need to determine following:
Does the cash register use a stand-alone receipt printer? If it does it can either be a serial or parallel printer. Serial
printers use DB9 , DB25 or RJ45 type connectors. However parallel printers generally use Centronics type connec-
tors, but on the cash register side use DB25. If it is a serial printer then you can use an AVE Triport DB9 or Triport
DB25.
USB ports are also commonly connected to printers. The AVE USB232 adapter will emulate a printer and output
RS-232 data to the RegCom-Pro. A software driver is supplied with the unit which needs to be installed on the PC prior
to running the POS software.
The RegCom-Pro can also interface with a parallel printer, if a high speed parallel-to-serial converter is connected with
either the cash register or with the printer. You can also use AVE's high speed serial-to-parallel converter "P2RS" for
interfacing the VSI-Pro to the parallel port. AVE's high speed P2RS converter is shown below.
Pole or Customer Displays are similar to printers and are either serial, parallel or USB and all the above also apply.
