Building security video subsystem with the use of Stretch (VRC6004, VRC6008, VRC6416) video capture cards one can install Sensor-Relay cards in order to connect external sensors and executive devices (relays) to the Server.
Connect Sensor-Relay card as follows:
Change the SW1 switch on the Sensor-Relay card in accordance with the table.
Sensor-Relay card | SW1 (1) | SW1 (2) |
Sensor-Relay card 1 | OFF | OFF |
Sensor-Relay card 2 | ON | OFF |
If sensors need power supply (active sensors), then set the J6 jumper to 2 and 3 contacts, otherwise – to 1 and 2 contacts (passive sensors).
The SW2 switch is used for the RS485 interface configuration. |
Sensor-Relay card is now connected.
