INSTALLATION

•Connect speaker output to loudspeaker.

•If RS-232 remote control is desired, connect the RS-232 REMOTE CONTROL port of the EF2241 to the remote control device, such as an RS-232 interface to a touch panel or a COM port on a personal computer.

•Connect the LINE RJ11 jack to an analog telephone line.

•Connect the PHONE RJ11 jack to an analog telephone set (optional).

•Connect the external power supply to the POWER SUPPLY INPUT jack of the EF2241.

•Set the country code on the EF2241. By default the phone interface will be dis- abled until you select a country code for the telephony interface. This can either be done with the front panel LCD menu, or the RS-232 interface. The country code only needs to be selected the first time or when the country of the installa- tion is changed.

DEVICE IDS ON THE EF BUS

When considering which Device IDs can be used for which Vortex device, decide how many devices have the ability to transmit on the W, X, Y, and Z 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. All devices that can transmit on W, X, Y, and Z must have unique device IDs. Vortex devices of the same type must have unique device IDs. If the device IDs of linked Vortex devices are the same, the front panel LCD screen will display “EFBus Error: Dev. ID Conflict”.

CONNECTING MULTIPLE VORTEX DEVICES

Up to 8 Vortex devices in combination 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 Vortex 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 BUS OUT of the first device, and the EF BUS IN of the second device.

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 BUS OUT of the second device and the EF BUS IN of the third device, and so on.

6.Power on all units at the same time.
