DKG-329 User Manual V-12

Some additional features are installed within consecutive software releases. In order to be sure
of the validity of the status of the unit, the software version needs to be known.
The software version of the unit is displayed together with the data
– time information.
The software version consists of 2 numbers. The first number represent the operating software
version of the unit.
The unit is capable of making modem calls in case of alarm, as well as answering modem calls
made from a remote location.
GSM
modems and classic cable network (
PSTN
) modems are
acceptable.
If the modem is connected to the unit, the
Modem Enable
program parameter should be set to
1, otherwise faulty operation may occur.
A maximum of 2 telephone numbers can be defined for outgoing modem calls. In case of alarm,
the unit will attempt to reach control centers associated with each number. In case of modem
connection failure, the call will be repeated up to 30 times with 2 minute intervals.
When the modem call is in progress, a telephone icon (
) will appear at the upper right
corner of the screen.
Advised modems are DATAKOM types which are powered up from the same DC battery
voltage than the unit. Most of other desktop modems with standard AT commands are also usable, but it
is the user’s responsibility to provide an uninterrupted AC supply source to the modem. The necessary
modem cable will be supplied by DATAKOM.
Modem calls are always terminated by the central RAINBOW software. However the unit does
not allow connection durations exceeding 2 minutes, and hangs up the modem when this period
expires.
The PC program used for remote monitoring and programming is the same RAINBOW software
used for RS-232 connection.
Please note that the modem operation is also compatible with the MODBUS communication.
Thus the unit can iniate and receive calls to/from a MODBUS master station. Please review chapter_8
for more details on MODBUS communication.
If
Modem Enable
or
SMS Enable
or
MODBUS Address
parameters
are different from zero, the local PC connection will not work.
