4. Operating Modes
4.1. 505 Operational Default
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).
4.2. 503AV Operational Default
The default for the 503AV interface is AV mode.
5. Installation
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.
5.2. 503AV Installation
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.
