Troubleshooting Guide
Symptom: Wash 1 at the pump is configured to be the most expensive wash and gives
a code for the cheapest wash.
Cause: EXT POS is configured for the reverse order as configured in the POS4000.
Solution: Set Reverse order configuration and POS Max Washes (See Sections 3.1.9.5
and 3.1.9.3)
Symptom: Receipt at pump or register is showing that code is good for that day only.
Code age warning is set to another number
Cause: EXT POS is using enhanced protocol commands
Solution: Enable “Set Send Code Age” function (See Section 3.1.9.4)
Symptom: Codes on ticket do not have 0 at end
Cause: Some manufacturers of Register Equipment only work with 5 digit codes
Solution: Set the code length to 5 digits
Symptom: Message
Αtimeout from unit 2" appears on screen of console when the site
controller is connected to the DB-9 connector of the console
Cause: Most all register/Site controller equipment is Earth grounded at the Signal end.
This may cause ground differentials when connected to Older POS4000 consoles.
Solution: You may want to purchase a POS4000 Update kit, which will include an
isolation transformer for the interface board and grounding instructions.
Symptom: Message
Α POS No STX XXX≅, Α POS no SOH≅ or Α POS BCC Error≅
appears on second line of console screen
Cause: The serial port of the console is receiving incorrect data from the Site
Controller/Register. You may have the wrong POS type selected from the
ΑEXT POS
MENU->

The Serial Baud rate may also not correspond to the BAUD rate on the Ext POS
Device.
Solution: Change the POS type or Baud rate to the correct one. Remember; when you
change the Baud Rate you must power down the POS4000 then power it back up after
making the serial baud change.
Symptom: Some of the washes work but the codes (as checked using the check code
key) are not the correct wash type.
Cause: The POS Offset value may need to be adjusted or the POS MAX WASHES
value is set incorrectly.
Solution: Review the above procedure concerning the POS offset. The POS MAX
WASHES value is typically set to 0 (feature disabled). This value is only used on
Chevron sites when connected to a Dresser/Wayne Wayne +
Symptom: Cashier ticket does not print out a code
