Appendix E : P2Rs/P2Rs-Pro Parallel To Serial Converter - AVE VSI-Pro Max Operation Manual

APPENDIX E
The VSI-Pro Max can also interface with a parallel printer, or commonly called Centronics printer that connects
to the PC or POS LPT ports. Using the AVE P2RS high speed parallel-to-serial converter with either the cash register or
with the printer will convert this parallel data to RS-232 that can be read by the VSI-Pro Max.
The P2RS-Pro is a multi-functional POS / Cash Register Interface peripheral. Similar to the P2RS the unit can
tap or emulate Centronics Parallel printer data from a normal or enhanced LPT port of any POS or PC. This data also is
exported via the Data RS-232 port in ASCII format to the VSI-Pro or VSI-Pro Max line of text inserters or directly to a DVR
for display or database storage.
The P2RS-Pro has the additional features that allow up to 16 units to be daisy chained on the AVE RS-485 two
conductor RegCom/Vnet network to deliver all the POS data to one serial port of a DVR or multiple VSI-Pro devices.
An additional high speed UART has been added to the P2RS-Pro to allow connection to any POS or Cash
Register port accomodating any baud rate, parity, and bit selections and higher speeds to accomodate the latest IRC
and communications protocol. This UART also is fully compatible with the standard 16550 PC Comport.
The P2RS-Pro is fully programmable by any PC or laptop running any communications program like Hyperterminal
for full configuration.
Advanced new software features for compatible devices, allow genlocking the DVR or Text inserter Time and
Date to the POS or Cash Register to insure a seemless record of POS journal to CCTV recording. Alarming the recording
device when POS data is recieved is also available.
NOTE: When connecting the P2RS or P2RS-Pro you must make sure that the CTS function is enable which by default
is disabled so that RS-232 data can be exported from Pin 8. Therefore JP3 must be ON and JP4 must be OFF. See
Appendix S Page 98, VSI-Pro Max Jumper Settings for additional information.

Centronics Parallel Printer Cables
Advise of your register printer output connector to meet
AVE Printer Cables before ordering.
1. 021-076-SF DB-25 Emulating Cable. This cable will
connect directly from the POS to the P2RS-Pro. This mode
will not require any printer connected on register.
2. 021-073-SF DB-25 Printer Tap Cable. This cable taps
the DB25 connector on the rear of the POS which
connects to the printer.
3. 021-077-SF Centronics Printer Tap Cable. This cable
taps the Centronics DB37 connector on the rear of the
printer.
