Installation ~ Networking Units

A G-Link network supports ✍ connection of a maximum of any combination of 8 AP400s and AP800s. It also supports up to 16 additional AP10s, for a maximum of 24 telephone

lines.

G-Link connections

Using the G-Link connectors, you can connect up to eight AP800/400s and 16 AP10 units, where the total number of microphone inputs does not exceed 64. Make connections between units in daisy-chain fashion using the short RJ-45 jumper (provided). If your units are further apart (maximum distance 20 feet), use category- five twisted-pair cable (10 BaseT).

For a single-unit system, no connection is required in either G-Link In or G-Link Out connectors.

Figure 2.4. G-Link Network Connections

To create a G-Link network

1.Insert a G-Link terminator (provided) in the G-Link In connector of the first unit in the network.

2.Connect the RJ-45 jumper cable (or Cat. 5 twisted-pair cable) to the G-Link Out connector of the first unit and to the G-Link In connector of the second unit. Continue connecting units in the same fashion.

3.Plug the G-Link terminator in the G-Link Out connector on the last unit to complete the network connections.
