Note:
When using the Suntronic model SM-960, you MUST set the maximum code length as
5 (see section 6.2.4). The SM-2000 allows you to use 5 or 6 digit codes.
As communication occurs between the POS4000 main console and an external POS system,
the second line of the POS4000 main console display will show the most recently processed
message. If any communication errors occur, error messages will be displayed. While these
messages mean very little to the operator, they can provide important information to Unitec
technical support. If you suspect there is a communication problem, it will be very useful if the
operator watches the second line of the display and notes any activity prior to contacting Unitec
technical support.
Codes generated for external POS type 1 limited to 5 digits in length (4 significant digits plus a
0). There are approximately 6500 possible 5-digit codes. If the valid codes database is allowed
to fill to the maximum of 5000 codes, it will increase the time required to generate a new code.
This increase in time may result in a communication error between the POS4000 main console
and the external POS equipment. This communication error results in either no code or an
invalid code being printed on the customer's receipt.
To prevent this, you can do one of two things. 1) Set the maximum code length of all codes to 5
(see Section 4.1.4). This will decrease the VALID codes database to 3000 and should therefore
prevent the problem, or 2) Periodically delete USED CODES and/or OLD VALID CODES from
memory by using the "Clear All Used" (see Section 4.11.4) and "Clear OLD Codes" (see Section
4.11.5) commands. This should be done often enough to keep fewer than 3500 valid codes in
memory. How many carwash codes are generated and how soon they are used will determine
how frequently old codes should be deleted.WIRING INFORMATION:
SIGNAL NAME PIN for 6.1 hardware
PIN for 6.2 and higher
hardware
Data INPUT 4 2
Data OUTPUT 3 3
SIGNAL GND 1 5
To distinguish 6.1 from 6.2 hardware, look at the label attached to the base of the unit. If the
MODEL field has "POS4000", then it is 6.1 hardware; if it has "POS4000/2" (or /3 etc.) then it is
6.2 or higher hardware. Note that the 6.2 and higher pin outs are standard for a 9-pin DTE serial
port.
If you have a console with version 6.1 hardware do not change the wiring of the cable, but
acquire an SA1606 adaptor to make the 6.1 console conforms to the latest pin outs. These
adaptors are available to Wash distributors Via Wash manufacturers or Directly from Unitec.
Note:
Optional Software is available for EXTPOS Connection at Secondary POS4000
Consoles.
