GPIO (General Purpose Input/Output Ports)
The device has seven GPIO pins that operate at TTL digital signal levels and can be set to high or low level (Push-Pull). The direction of the pins can be input or output (adjustable). The signal levels are the following:
| Input voltage (V) | Output voltage (V) | Max. current (mA) | |
| Logic low level | 0 – 0.8 | 0 – 0.5 | 30 |
| Logic high level | 2 -5 | 4.5 – 5 | 18 |
- Plug pin assignment 1-6: Configurable, 7: 5V (max. 500 mA); 8: Ground
- The recommended cable for the connectors is the AWG24 (0.2 mm2 diameter) or the generally used ‘alarm cable’ with 4×0.22 mm2 wires.
The maximum total current for the six GPIO pins is 180 mA, the max. supported input/ output voltage is 5V.
RS-232
The switcher provides a 3-pole Phoenix® connector for bi-directional serial communication.
The signal levels are the following:
| Output voltage (V) | |
| Logic low level | 3 – 15 |
| Logic high level | -15 – 3 |
Plug pin assignment: 1: Ground, 2: TX data, 3: RX data
OCS (Occupancy) Sensor
The switcher is supplied with a 3-pole Phoenix® connector (male), which is for connecting an OCS sensor.
Plug pin assignment: 1: Configurable; 2: 24V (max. 50 mA); 3: Ground
| The signal levels for the Pin 1 | Input voltage (V) | Max. current (mA) |
| Logic low level | 0 – 0.8 | 30 |
| Logic high level | 2 -5 | 18 |
The occupancy sensor connector and the GPIO port are not compatible with each other because of the voltage level difference, please do not connect them directly.
Setting a Dynamic IP Address (DHCP)
- Keep the Audio out button pressed for 5 seconds; all front panel LEDs start to blink.
- Release the button, then press it 3 times quickly. DHCP is now enabled.
Lock / Unlock Buttons
Press the VIDEO OUT1 and AUDIO OUT buttons together (within 100 ms) to disable/enable front panel buttons; front panel LEDs blink 4 times when locking / unlocking.
