Description
The Gasboy TopKAT mounted on top of the ASTRA pedestal and controls the dispenser
activation. The TopKAT communicates with the ASTRA through the first of its three
asynchronous ports. Port 1 is a dedicated RS-485 communication loop which allows the
TopKAT to control all functions of the ASTRA. Ports 2 and 3 can be set for either RS-232 or
RS-422 communications to a data terminal or computer. See
