3.6.2 Car Wash Controllers
The following requirements must be met in order for the Car Wash controllers to
communicate to the NeXGen controller.
Unitec POS 4000 “6.50” or newer
Unitec/Enterlink Any version
PDQ Any version
Notes:
1. The Ryko Code-A-Wash IV should communicate to the NeXGen using any version
of software. However, Ryko recommends that the controller be upgraded to the
latest version.
2. The Unitec software must be able to support External POS 1, 2 or 3. This
information may be found either on the PROM label which is located inside the
controller, or via the configuration report printed from the controller. There will be a
line on the report indicating the “External POS” type.
a. The Unitec controller must be programmed to use the Ryko protocol. See section
6.2.10 in the External POS Menu of the Unitec manual. Set POS offset to “0”,
Down. Set External POS type to “2”. Set baud rate to 9600.
b. If the Unitec hardware version is 6.1, a (SA1606) 9 pin adapter (which can be
ordered from Unitec, if required) must be used to connect the serial port to the
communication cable. If the hardware version is 6.2 or higher, the communication
cable must be connected directly to the 9 pin serial port.
c. To distinguish the difference between 6.1 type hardware and 6.2 type hardware,
look at the label attached to the base of the unit. If the Model field has
“POS4000” then it unit is equipped with 6.1hardware. If it has “POS4000/2” (or /3
etc.) then it is equipped with 6.2 or higher hardware. The 6.2 and higher cable
pinouts are standard for a 9-pin DTE serial port, which is not the case for
6.1units.
3. The Ryko Code A Wash II will not work with the NeXGen system. It can be upgraded
to a Code A Wash III.
