4.9 I/O ports
Figure 4-43
Pin 1: Ringer output
Pin 1 acts as a built-in switch in the terminal. You can configure
Pin 1 to be Normally closed or Normally open.
Pin 2: Warning/Error output
Pin 2 acts as a built-in switch in the terminal. Pin 2 can be used
to provide an external signal that indicates active warning/error
condition(s). You can configure pin 2 to be Normally closed or
Normally open.
Pin 3: Mute output
Pin 3 acts as a built-in switch in the terminal. Pin 3 can be used to
provide an external signal that is active during a phone call. The
signal can be used to mute external equipment. You can configure
pin 3 to Normally closed or Normally open.
Pin 4: Radio silence input
Activation of this pin causes the system to assume radio silence,
i.e. to stop all transmission from the system. The terminal gracefully
closes all open connections, and deregisters from the BGAN
network. No transmission is allowed until the pin is deactivated.
You can configure pin 4 to Active low or Active high.
Pin 5/8: Ignition input
The ignition function can be used to turn on/off the terminal by
means of an external signal. The external signal that triggers the
ignition function can be either positive DC voltage or ground. The
ignition function uses pin 5 together with pin 8 (DC in). Connect
the appropriate pin to the ignition switch as follows: indicated in
the Note!- box.
Pin 6: Ground
(Non-configurable) Pin 6 can be used as an external connection to
ground. Pin 6 is connected to Ground inside the terminal.
Pin 7: DC output
(Non-configurable) Pin 7 can be used as a DC output. The voltage
on pin 7 is 9-15 V and the output can supply up to 50 mA. Pin 7
can be used as power supply to a relay, ringer or similar.
NOTE!
Do not use the Ringer output
if you have enabled Local
exchange. For information on
Local exchange, refer to the
User manual.
NOTE!
•
Normally Closed:
The internal switch at pin X is
normally closed (connected
to ground). When the function
is activated the switch opens
(no connection to ground).
When the function is cleared
the switch is closed again.
•
Normally Open:
The internal switch at pin X is
normally open (no connection
to ground). When the function
is activated the switch closes
connection to ground). When
the function is cleared the
switch will open.
NOTE!
•
Active low (default): Connect
pin 4 to ground (< 1.2 V DC)
when it should be activated.
•
Active high: Connect pin
4 to ground (< 1.2 V DC).
When it should be activated,
disconnect it from ground.
NOTE!
•
Active high (default): Connect
pin 5 permanently to Ground.
Connect pin 8 to positive DC
voltage (10.5-32 V DC) when
the ignition is on. To switch
off, disconnect pin 8 from the
positive DC voltage.
•
Active low: Connect pin 8
permanently to positive DC
voltage (10.5-32 V DC).
Connect pin 5 to Ground
(< 1.2 V DC).
