Connection to 11-85SE Serial Port
To send a paging message to the 11-85SE using a serial port a Salcom 11-46 programming
adaptor cable must be used. The following lines from the PC or serial device serial port must be
connected:
GND
RXD
TXD
RTS
DTR
The 11-85SE serial port will only be available if RTS and DTR are set.
The RTS is used to power the 11-85SE serial cable. The DTR is used
to power on the 11-85SE.
By using the DTR line to control the power ON / OFF the 11-85SE
can used for serial paging messages with the internal 9-volt
battery.
The sequence for sending a message is as follows:
1.
Connect the serial cable to the 11-85SE
2.
Connect the serial cable to a PC or serial device
3.
To power on the 11-85SE set the DTR line
4.
Wait for 1 second
5.
Send Salcom Protocol paging message
6.
Wait for 500mS
7.
Release the DTR line.
If the DTR line is always set the 11-85SE will be powered up continuously and will draw
approximately 100mA. This will drain a 9 Volt battery very quickly and therefore a regulated 9
Volt supply should be used.
When the DTR line is set the 11-85SE red LED will pulse briefly once every second to indicate that
the unit is in its powered state.
