Configuring system parameters

4.1

Introduction

The system can be configured in one of two ways:

●

using the PC GUI

●

using the Control Module

The system is configured by entering Setup mode; this is possible only if the Central Unit

(CU) is in Idle mode (CU disabled).

During the first installation or each time a new module is installed or removed from the

system, the connected modules must be registered in the CU memory. When using the PC

GUI, the software automatically registers connected modules in the CU memory. When

using the Control Module, follow the instructions provided in Section 4.3: Configuration

using the Control Module.

4.2

Configuration using the PC GUI

This feature is not implemented in this version.

4.3

Configuration using the Control Module

At first installation, communication with the CM is impossible since no modules are

registered in the CU memory. For this reason (or each time a new module is installed or

removed from the system), press the Initial Setting button on the CU board for approximately

5 seconds. The CU scans the bus and registers all the modules installed on it. Once this

procedure is successfully completed, the CM displays the system date/time and the CU

status (OFF) as shown in Figure 10.

Note:

Pressing the Initial Setting button resets all the system settings on the CU to their factory

settings (except for the system date and time).
