Digidim 503AV / 505 RS232 AV Interface User Guide

1. Overview

The DIGIDIM RS232 interface provides the means of interconnection between a Digidim

Lighting Control System and an RS232 port. Communication is bi-directional. The interface

itself is functionally passive and serves only to link the communications between the

computer (or equivalent) and DIGIDIM. The 505 interface uses the industry standard 9-pin

D-connector, allowing direct connection to such as a PC compatible serial port. The 503AV

interface is a DIN-rail mounted module, more suited to fixed installation applications.

The interface module's power requirements are derived from the connecting systems.

Opto-coupling is used for the internal link of the two systems to provide double-insulation

between them.

Note:

You must install Digidim 'Toolbox' Software to utilise the functions of the AV

interface with a Digidim Lighting Control System.

DIGIDIM is Helvar's implementation of the application of DALI to controls and load

interfaces. It is possible that a DIGIDIM system may contain a mixture of devices, including

third party DALI-compliant ballasts or dimmers. For this reason, the User Guide often refers

to aspects of the DALI standard.

By definition, when connected to a lamp interface, DALI is recognised as having basic

insulation from the mains supply only, and is therefore deemed a live connection. In

consequence, the module is constructed to offer a double-insulation rated barrier to the

RS232 serial interface and the user, when correctly installed.

Connection to DALI should be by use of mains-rated cable to a double-insulation

specification and using a shrouded connector. The low voltage power supply to the DALI

components should always be isolated prior to connection to – or work with – the DALI

components. Where appropriate, the use of the Helvar DIGIDIM 180 Programming Point

panel and proprietary connecting lead offers a means of a double-insulation connection,

without powering down the DALI system.

Isolation is 3kV between the RS232 and DALI.

The byte format is 19,200 baud by default; 8 data bits, no parity and 1 stop bit.

No control or handshaking is used.
