PURPOSE OF THE DOCUMENT

This Technical Guide is intended for studying of Tokheim fuel dispenser interface converter. It contains basic information regarding its board interfaces and connectors, configuration and adjustment, connection to fuel dispensers, cablings. Information regarding connection to specific models of fuel dispensers and correspondent configuration of the Tokheim interface converter can be received upon request to TECHNOTRADE LTD company. Due to a reason that Tokheim interface converter is constantly being developed in direction of improvements of its possibilities, changes are possible in final version, which are not described in given Technical Guide. During the system development process given Technical Guide will be also expanded and updated and new chapters will be added. Latest version of this Technical Guide can be downloaded from the Tokheim interface converter web-page: http://www.technotrade.ua/tokheim_interface_converter.html. TECHNOTRADE LTD hereby permits reproduction of this document as may be required by any of the customers or OEMs wishing to use it. This document has been carefully prepared and is believed to be accurate. However TECHNOTRADE LTD, its employees and its agents do not assume responsibility for its use either directly or indirectly.

TOKHEIM INTERFACE CONVERTER TECHNICAL FEATURES

Appointment Tokheim dispenser interface converter (current loop to RS-485/RS-232 and backwards) is intended for communication with Tokheim fuel dispensers through interfaces:

- RS-232, - RS-485 (half-duplex), - RS-485 (full-duplex), - RS-485 (half-duplex with control over RTS) – used for PTS controller over fuel dispensers and ATG

systems for petrol stations (http://www.technotrade.kiev.ua/fuel_pump_controller.html).

Specification Power supply voltage +12 V DC Current consumption 100 mA max Temperature range -40°C ÷ +80°C Weight 100 g Dimensions 145 x100 x 20 mm Technical characteristics Current level in current loop interface in TTD line (transmit to dispenser)

Adjustable using jumpers XP7, XP8, XP9, XP10, located on Tokheim PCB board, selected values: 10 mA, 12 mA, 15 mA

Current level in current loop interface in TTC line (transmit to controller)

Adjustable using jumpers XP11, XP12, XP13, XP14, located on Tokheim PCB board, selected values: 20 mA, 35 mA, 55 mA

TOKHEIM CONVERTER BOARD CONNECTORS OVERVIEW

NOTE! Jumpers XP4, XP5, XP6 serve for selection of interface:

- RS-232, - RS-485 (half-duplex), - RS-485 (full-duplex), - RS-485 (half-duplex with control over RTS) – used for PTS controller over fuel dispensers and ATG

systems for petrol stations.

Jumpers XP7, XP8, XP9, XP10 serve for selection of current level in TTD line (transmit to dispenser) for each of the pump channels:

- 15 mA (close pins 1 and 2), - 10 mA (all pins opened), - 12 mA (closed pins 2 and 3).




Jumpers XP11, XP12, XP13, XP14 serve for selection of current level in TTC line (transmit to controller) for each of the pump channels:

- 35 mA (close pins 1 and 2), - 20 mA (all pins opened), - 55 mA (closed pins 2 and 3).
