VS-910RS Substation Interface Card
VS-910RS
The VS-910RS Substation Interface Unit is used to connect the Full-Duplex Substation by way of 2 sets of twisted pair cables. Up to 16 Full-Duplex Substations can be connected per unit. The VS-910RS has 2 speech paths, either of which can be used for substation paging.
