The following steps are typically used to set up the EF2280:
• Connect a microphone to each of the 8 mic/line level inputs. The mic/line
input accepts mini-Phoenix connectors. See "Connector Pinouts" on
page 58 for pinouts of Phoenix connectors.
• Connect one line output to an amplifier or powered loudspeaker.
• If RS-232 remote control is desired, connect the RS-232 R
port of the EF2280 to the remote control device, such as an RS-232 inter-
face to a touch panel or a COM port on a personal computer.
Note.
If you are linking multiple Vortex devices, you must use the
EF bus to link the units.
• Connect the external power supply to the P

When considering which Device IDs can be used for which Vortex device,
decide how many devices have the ability to
busses, and how many have the ability to transmit on the P Bus. The EF2280,
for example can only transmit on the W, X, Y, and Z busses while the EF2241
can transmit on the W, X, Y, and Z busses as well as the P bus. Up to 8
devices can transmit on the W, X, Y, and Z busses. Similarly, up to 8 devices
can transmit on the P bus. Note that the EF2241 counts as one of both types.
Vortex Devise
Up to 8 Vortex EF2280 devices can be linked together at one time (See Device
IDs on the EF Bus above). Each unit in the chain must have a unique Device
ID. Use the EF Bus to link multiple Vortex devices together.
The following steps should be followed to connect the EF Bus:
1. Set a unique Device ID for each device. The Device IDs range from 00 to
07.
2. Power off all units.
3. Connect the RS-232 remote control device to any Vortex device in the
chain.
4. Connect the provided Cat-5 cable between the EF B
device, and the EF B
Note.
The EF Bus must be connected so that the EF Bus In of one
box is connected to the EF Bus Out of another. Connecting
the EF Bus In to another EF Bus In (or Out to Out) will not
work.
5. Connect another Cat-5 cable between the EF B
device and the EF B
6. Power on all units at the same time.
