Multi Point Controller For WP2P Modules Quick Start Guide
QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 2 Introduction The QTech Multi Point Controller is a powerful controller for communicating with up to eight WP2P (wireless point to point) modules over a range of several kilometres. It has a sophisticated mapping grid that allows any of the inputs and outputs to be mapped to any module in the system.
QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 3 Power Supply Connections – Multi Point Controller The Multi Point Controller is powered from an external 12-30 V DC supply. Connect the supply to the power connector, positive to the “+V” terminal, negative to “GND”. The third terminal on the right is not used. We recommend the QTech plug pack P/N PD5412. Power Supply Connections – WP2P Modules The WP2P operates from a 12 Volt DC power supply.
QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 4 Workbench User Interface This is where the configuration of the Multi Point Controller takes place. There is no configuration of the WP2P modules. Overview – Number of WP2P Slave Modules. This is where the number of WP2P modules in the Multi Point Controller system is defined. There can be a maximum of eight modules. Ideally, the amount of modules is defined when the system is purchased so QTech can preconfigure them.
QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 5 The Number of Retries setting specifies the number of times that the Controller will transmit a poll to a given WP2P module before determining that communications with that module has failed. For each communications attempt, the Controller will wait for the Retry Timeout before re-attempting.

QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 7 I/O Link Editor – Example 2 Advanced This example is more sophisticated and shows that each WP2P module can essentially communicate with each other, with communications via the Controller. Multiple links can be configured for any input or output anywhere in the system.
QTech Multi Point Controller for WP2P - Quick Start Guide – v1 – August 2012 8 Inputs and Outputs – Multi Point Controller Digital Inputs The digital inputs are normally open inputs that can be connected to suitable mechanical switches, contacts and other closure devices. An input is active or ON when the input switch is closed, and inactive or OFF when the input switch is open.

The supplied stub aerial (P/N PD9230) should be suitable for ranges of up to 350m and where the Controller is in a non-conductive enclosure (plastic etc). Optional alternative externally mounting aerials are available from QTech.
