the lights is blinking, you may have a failed connection, or a failed POS4000. A
failed communications module is also possible.
4. Enter the POS4000 Link sub menu and enable the interface by enabling the
“Interface Mode”.
5. If you have a multi-bay system, you will have to set the bay addresses (Wash 1 is
Bay 2, Wash 2 is Bay 3 etc).
6. Set the unit to “Operate Mode”. You should see both the RX and the TX lights on
the Wash Select II
™ 485 communications module begin to blink within 10
seconds. They should blink one after the other with a pause of less than 1 second
between blinking. If you have more than one bay, the RX light should be on
longer than the TX light.
7. Set the unit back into “Setup Mode” and continue configuring the other settings
from in the POS4000 link per the operations manual, if necessary.
8. Configure the POS4000 as per the POS4000 manual. POS4000 will download
pricing and naming information to a Wash Select II upon power up or after
discontinuation of communications with a Wash Select II for over 20 seconds
5.5 Multi-unit Fleet System (Optional Feature)
Up to 6 Wash Select IIs can be connected together for a multi-unit fleet system operation, in
which one of the Wash Select IIs will be the master and all the rest remotes. This system
enables the sharing of fleet accounts generated at the master at all the bays. The master
needs to be in operation mode for validating fleet account verification requests from the
remotes.
Keep in mind that you don’t need a POS4000 for this system. All you have to do is daisy
chain the Wash Select IIs as you would daisy chain them for Wash Select II/POS operation,
only without the POS4000. This is an optional feature and requires a plug in module (the RS-
485 board) for the Wash Select II (comes with the Wash Select II multi-unit fleet system). A
remote unit is sometimes referred to as a secondary unit.
Here is a guide for getting the Wash Select II-MULIT-UNIT-FLEET system to communicate
with each other:
1. Wire the communication cable connections per the following connections:

Turn on the Wash Select II
™ and put it into “Setup Mode”. If you have more than 1 bay, set
the system up one at a time, with un-configured units turned off.
