TH dispenser interface converter

PURPOSE


TH 3-wire interface converters (RS-485/RS-232 to 3-wire current loop and backwards) are intended for communication with dispensers using 3-wire current loop interface through interfaces:

The TH interface converters can be used for communication with following brands of fuel dispensers, which use 3-wire current loop for communication with control systems: Tokheim, Satam, Emgaz Dragon, Kalvacha, Kraus, others.

The TH interface converters have 2 board modifications:

PORT NAMEINTERFACEPURPOSE
DATA PORT RS-232 RS-232
(3 wires: TxD, RxD, Gnd)
Communication with a control system (POS terminal, cash register, OPT). Selection of interface is made using DIP-switch
DATA PORT RS-485 RS-485
(2-wires: line A, line B)
PUMP PORTS Optically isolated passive current loop Connection with fuel dispensers using 3 wires (TTD, TTC, DCC). Separate dispensers have to be connected to each of the pump ports. Selection of current value in current loop line TTD of pump ports is made using DIP-switches
PROGRAM PORT RS-232
(3 wires: TxD, RxD, Gnd)
Update of the interface converter firmware
