information on custom programming for this device
Installation Location
–
Install in a dry location, close to the
equipment to be interfaced with.
RS232 Cable Length
- Should not exceed 15 meters for baud
rates up to 9600. Baud rates higher than 9600 may require
maximum RS232 cable lengths of less than 15 meters.
RS485 Data Cable
–
Use screened, stranded RS485 data cable
with three twisted pairs. Segregate from mains cables by 300mm
minimum. Connect devices in a ‘daisy chain’
. A data cable that is
connected to an energised device is live. Do not cut or terminate
live data cables.
The factory settings will allow control of a Dynalite system via plain English text strings which can be easily sent from a terminal program.
To use the Microsoft terminal program, from the Start menu go to Programs > Accessories > Communications > HyperTerminal, then
enter any name for the connection then select your PC’s COM port (usually COM1) at 9600 baud with no flow control.

be sent and received via automation software. To facilitate this the astrix character * may precede a command to flush the transmit buffer
of any information, eg.
* Channel 4 Area 1 Level 70 Fade 3 <CR>
Note the preceding * which will flush an
y existing information from the transmit buffer, see the “help” function for more details.
