Appendix B. Multiple Unit Configuration
Note: The terms unit number and address are interchangeable.
The POS4000 system is capable of controlling multiple customer interfaces (carwashes or bays)
and multiple points-of-sale (POS4000 consoles). This is a Standard feature for Version 2 units. If
this feature is not present and you want to acquire it, you should contact your carwash sales
representative to order a software upgrade. The same version of software must be used on each
console you have on the same system. In addition, the software in the Entry systems must also
be of the same version if you are using entry systems with the Unitec POS4000 interface board.
If you are using multiple Hamilton Autotecs please contact Hamilton MFG for any questions on
compatibility.
Each console and customer interface board is connected to the 2-wire communication network
and is assigned a unique unit number or address. A single POS4000 controller (main) console
must act as the network controller. Additional POS4000 consoles may be connected to the
network to provide additional points-of-sale, these are referred to as remote consoles.
A controller console must have an address of 1. Customer interfaces must begin at address 2
and continue sequentially. The addresses of remote consoles must begin after customer
interfaces and continue sequentially. The unit number of a customer interface is determined by
DIP switches located on the customer interface board (refer to the layout drawing in the back of
this manual for position and setting of switches). The unit number of a POS4000 is set by using
the "Set Unit Number" command (see Section 4.1.11.1). Unit numbers for Hamilton Autotec
Coin boxes are determined by a wire harness change in the Hamilton coin box. Contact
Hamilton MFG for a reference to this harness change.
Upon changing bay configurations, any prior accounting reports should be printed out first.
Adding a Wash Select II, for instance, or changing the bay number of the remote console could
cause you to lose the accounting information associated with the remote console.
Unit numbering examples:
A system with 1 POS4000 and 2 customer interfaces (2 carwash bays):
1 controller console with address 1.
2 customer interfaces with addresses 2 and 3.
In this example the console is set up to have 2 bays and 0 remote consoles
A system with 2 POS4000s (One Controller and 1 remote) and 1 customer
interface (1 carwash bay):
1 controller console with address 1.
1 customer interfaces with address 2.
1 remote consoles with addresses 3.
In this example, the controller console is set up as the controller at address 1, to have 1 bay and
1 remote console. The remote console is set up to be a remote, address 3, 1 bay and 0 remote
consoles.
In addition to controlling the communication network, the network controller generates all
customer codes (including ones printed at remote consoles) and maintains the database of valid
