Digidim 503AV / 505 RS232 AV Interface User Guide

4. Operating Modes

The interface can operate in several modes. From power up (of the DALI supply), the 505

interface's operational default is for Helvar DIGIDIM 'Toolbox' Software. The mode

command is required to activate the interface for AV use. (Note that the reply message to

the mode command contains the interface firmware revision).

The default for the 503AV interface is AV mode.

5.1. 505 Installation

If the DIGIDIM system that you want to configure does not include a 180 programming

point, one must be installed before the RS232 connection can be used.

Important Notes:

Before installation, isolate the circuit.

All DIGIDIM cabling must be 230v mains-rated.

For safety reasons, do not connect the interface other than with a correctly installed

programming point (see document '180 Programming Point (I438M1)', included on the

CD within the 503 package).

Connect the adapter directly to the serial port (9-way D-type). If you are not sure which

connector is the serial port, refer to your system documentation.

The DIN-rail mounted 503AV interface is intended for installation in a protected enclosure

or area. Always follow safe practice when working in a protected area. Digidim and RS232

connections are made directly at the module. Mains-rated cable must be used for Digidim

and preferably segregated from the RS232.
