The digital ports of the GSV-8 can be equipped with predefined functions, e.g.
The triggering of a single measurement,
The triggering of a measurement as long as the port is active,
The indication of a threshold value overshoot,
and much more.
If two or more GSV-4 or GSV-8 are to be synchronized, this can be achieved by configuring the devices in master / slave mode.
The desired data frequency is set on the device configured as the master.
The devices configured as slaves send measured values at the request of the master.
The (internal) data frequency on the slave must also be set to at least as high as on the master. Otherwise, no measured values are available in the requested frequency. The slave then sends the same measured value several times.
With the GSV-8 only the ports 13 ... 16 can be configured for the master-slave mode.
The article "GSV-8DS Sync-cable" the IO Port 16 is used (PIN13). Reference ground GND is PIN 5.
