Document Number: POS4003 125
Document Title: POS4000/V2 Operations Manual
Baud Rate:
Speed of communications rate between Carwash POS Unit and EXT POS.
Typical values used are: 2400, 9600 or 19200.
POS (feature) Offset:
This offset value is applied to the wash request from the EXT POS unit. For
Example:
POS Offset value is 1 up
EXT POS unit requests a code for Wash 1 (Key 1 on POS4000)
The Unitec Carwash POS unit will shift the request by 1 in the positive (up)
direction. Thus processing the request as for a Wash 2 (Key 2 on the POS4000)
POS Max Washes:
This is the maximum wash number that the Unitec Carwash POS Unit will
respond to a code request. All requests above this value will be acted upon as if
the POS Max Washes Value were subtracted from the Original request.
Example:
POS Max Washes is set to 3
Requests for washes 1,2, and 3 are unchanged (processed as 1,2 and 3
respectively)
Requests for washes 4, 5, and 6 are shifted down by 3 and are processed as 1, 2
and 3 (request for wash 4 processed as wash 1, request for wash 5 processed
as wash 2, and request for wash 6 processed as wash 3)
This feature was added to adapt to the Chevron/Dresser-Wayne application.
Note that POS Max Washes value is applied before the POS Offset. This feature
is also used when configuring the Reverse order function (See section 6.2.10.5)
External POS Type:
This is the Protocol type used to communicate from the Carwash POS unit to the
EXT POS device. The proper POS Type must be used for each particular EXT
POS device. Unitec’s POS unit’s Manuals will have an appendix with a chart
showing the required POS type for each EXT POS device. This chart is also
sent a part of a Unicam Upgrade for the POS4000 units. POS 1 and POS 2 are
Ryko emulations and POS3 (also at times referred to the Unicam Protocol) is
maintained by Unitec. POS0 is an obsolete Modem connection not used any
more. Note that POS4000 consoles shipped without the Unicam option are
configured for POS0 to be the default. Chips with POS0 as the default cannot be
changed to POS 1, 2 or 3. E-System POS4000 consoles and Enterlinks come
