NetworKam provides a very flexible general I/O interface to combine with the user’s security devices 

such as sensors, alarms, lighting or door locks. The general I/O terminal block has six pins for device 

control. These pins can be divided into two categories based on their functions, including RS485 and 

digital inputs and outputs.   

 

If the device connected to COM has an RS485 interface, wire two control lines to pin 5 and pin 6. After 

switching to RS485 on the configuration page, the PT control commands will be directed through pin 5 

and pin 6. If the distance from the controlled device is too far to allow accurate function, an external 

power source may be used to pull high the RS485 signal. 

 

NetworKam provides one digital input and one relay switch. Pin 1 and pin 2 can be connected to external 

sensor and the state of voltage will be monitored according to the programmed scripts in configuration. 

The relay switch can be used to turn on or off external devices.
