12 Installation ~ Networking Units

✍ If the same device ID is assigned to more than one unit on the E-bus network,

the Meter LED “+12” will flash red and the Mic LEDs “1,” “2,” “4,” and “8” will flash green on the affected units. To correct the problem, change the device ID on one of the conflicting units.

Device IDs

Once your expansion bus connections are made (and if you have more than one PSR1212 at a site), you need to set up a unique expansion bus device ID number—a network address—for each PSR1212 on the network. As shipped from the factory, all PSR1212s are set to device ID 0.

To assign device IDs

1.Press the front-panel Enter button, then scroll through the menu until the System menu is visible.

2.Press Enter, then scroll through the menu until Device ID is visible.

3.Press Enter, then scroll through the eight (0–7) options. When the desired device ID is visible, press Enter to select it. (You can also set the device ID in the Unit Properties window of G-Ware software. See page 25.)

4.Repeat this process for each PSR1212 on the expansion bus network.

	You can also use G-Ware
✍ to select		a mixer mode.

Mixer mode

There are two mixer mode settings: slave (default) and master. A master unit is not required in a networked system and in most installations, all units will be slaves. Master units ignore audio from upstream units. This prevents audio from being received from units above the master unit in the network. However, global control of the system is still maintained by whichever PSR1212 or XAP 400/800 unit is connected to a control device through its RS-232 or RS-485 ports. Control is not affected by master/slave designations.

In Figure 2.5, the third unit in the network is a master. It prevents the audio from the first and second units from being passed down the network chain. Likewise the second master unit in the network will not pass on the audio from the unit before it. The third unit provides system-wide control through a connection to its RS-232 port.

To select a mixer mode

1.Press the front panel Enter button and scroll through the menu until System menu is visible. Press Enter to select the menu.

2.Scroll through the System menu and select Mixer Mode.

3.Select the mixer setting you want to use. Repeat for additional units.
