Bussing The Units; Connecting Via Rs232 - Polycom EF2201 Application Note

To do this, apply power to the Vortex EF2280 that needs to have its device ID
changed. Enter the front panel System Settings by pressing the "up" button on the
front panel until System Settings is shown on the LCD. Press the "enter" button to
enter this menu tree. Continue pressing the "up" button until the device ID of the
device is shown. By default, each device is set to Device ID 00. Press "enter" on
the front panel to make the device ID number flash. Press the "up" button to
increase the device ID to 01. Press "enter" again to make the device ID stop
flashing and to save the new device ID. The device ID has now been set to device
ID 01.

Bussing the units

Once the device ID's are set properly, the devices can be bussed together using
the supplied EF bus cable. Each device's EF bus out connector should be
connected to the next device's EF bus in connector. Please note that the last
device should NOT be connected back to the first device and that bus terminators
are not required with Polycom Vortex devices.
Once the devices are connected, the remaining devices may be powered on.
After several seconds, the devices will boot up and display the default LCD menu.
If a Device ID conflict message is shown on the LCD, it means that more than one
of the same type of Vortex product has the same device ID. Please double-check
the device ID's and recycle power on the devices.

Connecting via RS232

Finally, once the devices are bussed together, the Conference Composer design
file may be uploaded to the linked devices. Connect an RS232 cable from your
PC to the RS232 port on one of the linked Vortex devices. To specify which
RS232 port will be used, left click on the device chain, as shown in Figure 24, and
select the appropriate transport (such as Com 1, Com 2, etc.) as shown in Figure
25.
