Device IDs
Once your physical G-Link network is established (and if you have more than one AP
unit at a site), you need to specify unique device ID numbers for each AP400 on the
network. As shipped from the factory, all AP400 units default as device ID “0”. Set
device ID numbers for each unit at your site by manipulating the front-panel LCD.
To set the device ID
1. Press the System button, then scroll to Device ID.
2. Press Enter, then scroll through the eight (0–7) options.
3. Press Enter to select the appropriate device ID. Repeat this process for each
AP product on the G-Link network.
If the same Device ID is assigned to more than one unit of the same type on
the G-Link network, Meter LED “+12” will flash red and Meter LED “0”, “-4”,
“-30”, and Mic 4 will flash green on the affected units. To correct the problem,
change the device ID on one of the units.
Device types
Device IDs are automatically assigned a device type. AP400s are always device
type “3” (AP800 device types are “1”, AP10 device types are “2.”). The device
ID # selected is added to the device type “3” to generate the unique address for
that unit. For example, the first AP400 unit in your G-Link network would be
identified as “30”, “3” being the Device Type, and “0” being the Device ID.
Mixer mode
Once your physical G-Link network is established and unique G-Link device ID
numbers for each AP400 on the network are established, the mixer mode must be
set. There are three mixer-mode settings: master-single (default), master-linked, and
slave.
• Master-single must be used when only one AP400 is used in a system.
• Master-linked denotes the master AP400 unit when more than one AP400 is
on the network; only one AP400 can be designated as master-linked when
multiple AP400s are used in a system.
• Slave is used for all networked AP400s that are not designated as master-
linked or master-single. If two AP400s are part of the same system, set one
with the master-linked parameter. Set the other with the slave parameter.
