User Manual for Secop Gateway 105N9518

Quick guide from the manual

The Secop Gateway 105N9518 is an interface device designed to connect Secop compressors to a PC. It replaces the older 105N9501 interface and is compatible with all existing Secop electronic units (controllers) featuring a communication interface. The device supports two communication modes: Transistor interface (I, D/I, or COM) and LIN interface. The mode is determined by the connection status of the U+/UBAT pin.

Package contents

• Secop Gateway unit
• USB 2.0 A/C cable
• Gateway communication (Comm.) cables for various Secop compressor series/controllers

Installation and connection

The gateway connects via USB to a PC and via the communication cable to the compressor controller. Ensure you follow the specific connection requirements for your compressor series:

• BD-Series Compressors: Connect the communication cable to the controller. Note that the U+/UBAT pin should only be connected when using a BD controller equipped with LIN. On BD controllers equipped with a communication line labeled I, D/I, or COM, the U+/UBAT pin must not be connected.
• DLV, NLV, SLVE Compressors: Follow the specific wiring diagram provided in the manual for these series to ensure proper communication.

Communication modes

The gateway automatically switches modes based on the U+/UBAT pin connection:

• LIN Mode: Activated when the U+/UBAT pin is connected to a battery.
• Transistor Interface Mode: Activated when the U+/UBAT pin is left disconnected.

Driver installation

To ensure proper communication between the gateway and your PC, you must install the latest Virtual COM Port Driver. This driver is provided by Future Technology Devices International Ltd. and can be downloaded from www.ftdichip.com.
