Document Title: Remote Code POS4000 Installation and Operations Manual
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
and used codes. Only accounting information from the Controller console is valid. Any
accounting information, or code database information on the remote console is invalid.
NOTES:
1. The following commands are NOT available on Remote consoles:
MEMORY INFORMATION
SET PRICING
CLEAR AUDIT COUNTS
All other commands are available at the remote consoles.
With standard software, EXT POS connection is only possible with the Controller console.
EXT POS connection is not functional from a Remote Console.
With the Optional Remote Extpos Connection Software, EXT POS connection is possible
with any console (Controller or Remote console). Each console can be configured to interface
to a different EXT POS. If a remote console is connected to an EXT POS that requires the
code length to be 5 digits, then the code length MUST be changed to 5 on the Controller
console, which will automatically change the code length for all the consoles.
2. When the following commands are executed at a controller console which has 1 or more
remote consoles connected to it, the related information will be automatically downloaded to
all remote consoles:
SYS SETUP - Set Time, Set Code Age Warning, Disable Cashier Key, Code Length
SET PRICE - Set any price level, Set Tax Rate, Set Tax Round Off
SETUP FEATURE - Change Wash Name
If a remote console is off-line while these items are programmed at the controller console, this
information will NOT be downloaded. If this happens, the "Program Remote Consoles"
command (see Section 3.1.10.4) can be used to download all parameters to all remote
consoles. Executing this command causes the Controller to download the following
information to all remote consoles: Prices, Wash Labels, System time, Code age warning,
Disabled cashier keys, Tax rate and Tax round off status, and Code Length.
3. When connecting additional units to the communication network, you should simply daisy
chain from one unit to the next. Pin 1 of all units should be connected to the same conductor,
(RED) and all pin 2's should be connected to the same conductor (WHITE). The order in
which units are physically added to the network is not significant. Power should be OFF at all
units while making wiring changes.
The shield of the communication cable should also be daisy-chained at each unit. However,
the shield should only be connected to an EARTH GROUND at 1 end of the cable. For
systems with Unitec POS4000 interface boards the Shield should be connected to Pin 4 of
one of the interface boards only and should not be directly connected to any other interface
board, Console, or Earth ground point.
