Appendix #2 - COM / GPIO Terminal Block / Female BNC
The GPIO & COM provides a control signal input and output, which includes:
• One GPIO input
• One GPIO output (Relay connection)
• One RS-485 port multiplex with COM port.
The GPIO & COM port provides a connection for PTZ devices or an external
console to control the device. A motion detection or sensor unit can also be
used to send a signal to begin camera recording (when configured in the
DigiViewer Menu settings or compatible 3rd party software).
GPIO Pin Out Configuration
1. GPIN - Input high when opening
the connection; input low when
sinking more than 10mA or
shorting to pin 5 (GND).
2. RXD - COM Port Receive Data.
3. TXD - COM Port Transmit Data.
4. RS485 (A) - Connect an external
PTZ or Alarm device. For PTZ
control both pins 4 & 8 must be
used.
5. GND (System Ground) - The
System Ground is also
connected to the chassis as
frame ground.
6. GPOUT (Automatic Relay) -
When the DigiViewer is
configured to use the GPIN or
Motion detection to trigger alarm
devices, the “Relay Out” must be
turned on.
7. GPOUT (Automatic Relay) - When the DigiViewer is configured to use the GPIN or Motion
detection to trigger alarm devices, the “Relay Out” must be turned on.
8. RS485 (B) - Connect an external PTZ or Alarm device. For PTZ control both pins 4 & 8 must
be used.
9. BNC Type (Video Out) - Use the GPIO cable provided with this camera to directly output the
video to a monitor.
