5.4.5 SERIAL PORT
This section is included to give information about the currently selected serial port and external modem (if
connected).
The items displayed on this page will change depending upon configuration of the module. You are referred to your
system supplier for further details.
NOTE:- Factory Default settings are for the RS232 port to be enabled (no modem connected), operating
at 19200 baud, modbus slave address 10.
Example 1 – Module connected to a RS232 telephone modem.
When the DSE7300 series module is power up, it will send ‘initialisation strings’ to the connected modem. It is
important therefore that the modem is already powered, or is powered up at the same time as the DSE7300 series
module. At regular intervals after powerup, the modem is reset, and reinitialised, to ensure the modem does not
‘hang up’.
If the DSE7300 series module does not correctly communicate with the modem, “Modem initialising’ will appear on
the Serial Port instrument screen as shown overleaf.
If the module is set for “incoming calls” or for “incoming and outgoing calls”, then if the modem is dialled, it will
answer after two rings (using the factory setting ‘initialisation strings’. Once the call is established, all data is passed
from the dialling PC and the DSE7300 series module.
If the module is set for “outgoing calls” or for “incoming and outgoing calls”, then the module will dial out whenever
an alarm is generated. Note that not all alarms will generate a dial out, this is dependant upon module configuration
of the event log. Any item configured to appear in the event log will cause a dialout.

Indicates that a modem is configured. Shows ‘RS232’ if no
modem is configured or ‘RS485’ if the RS485 port is selected.
