4.15 Connecting a Mobile Computer
To operate with the E4000, a mobile computer plugs into a 9 pin serial connector on the junction box. Red
Seal has prepared a communications protocol document specifying how a computer can interface directly
to the register. The protocol allows the external computer to extract data and control the operation of the
register from a position in the cab. Application developers wishing to interface their product to the E4000
should contact Red Seal directly.
