Wash Select II interface and configuration

WashMax can work with the Unitec Wash Select II teller.
The Wash Select II and POS 4000 manuals are attached to the end of this article.

Hardware Interface

Configuration a Moxa:

For a Moxa nPort 5110, use a null-modem adapter.

Moxa settings:

TCP Server Mode
Serial port settings:

Baud: 9600 baud
Parity: None
Data Bit: 8
Stop Bit: 1
Flow Control: None
UART FIFO: Enabled

Set the IP address to something that works on the network. If connected into the Site Server's Auxiliary Connection #1, the teller's IP is typically 192.168.111.21. Set this same IP in EPG on the setting's Unitec tab.

Teller Configuration

Setup Generic Terminal Mode with extensions enabled.
Enable "Accept Proprietary".

Works best when washes are defined with the lowest end wash as wash type 1, with prices increasing with higher wash types.
