NA dispenser interface converter

PURPOSE


Dispenser interface converter NA (RS-485/RS-232 to non-addressable RS-422/RS-485/RS-232 and backwards) are intended for communication with fuel dispensers, which do not have a communication address in communication protocol and use one of the following interfaces:

The NA interface converters can be applied for communication with following brands of fuel dispensers: Censtar, Lanfeng, Sanki, Changlong, Blue Sky, DongHwa Prime, others.
