Daisy Chaining Multiple GPI and Tally Interfaces
The GPI and Tally Interface supports 8 GPIs and 8 GPOs at a time, which should be enough for
most live television situations. However, if you have more than 8 cameras then you may want to
daisy chain a second or third GPI and Tally Interface.
The GPI and Tally Interface has two ethernet ports so that you can connect one port to a
Videohub and use the other port to link other GPI and Tally Interfaces together.
1
Connect power to the first GPI and Tally Interface.
2
Connect a standard RJ45 ethernet cable from your Videohub or network to the
ethernet IN port on the GPI and Tally Interface.
3
Connect power to the second GPI and Tally Interface.
4
Connect a standard RJ45 ethernet cable from the ethernet OUT of the first GPI and
Tally Interface to the ethernet IN port on the second GPI and Tally Interface.
This can be repeated for as many GPI and Tally Interfaces as you need as long as power is
supplied to all units in the chain.
Sometimes it can get confusing to know which GPI and Tally Interface you are working with
when you have several connected. Select the GPI and Tally Interface in the Videohub Control
Panels pane and click the Identify button. The LED next to the ethernet IN port on the selected
device will light up.
Daisy chain multiple GPI and Tally Interfaces using ethernet.
Power must be supplied to each individual unit in the chain.
