Power Connections

The switching power supply is designed to operate properly from any AC power source 100–240V, 50/60 Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only an IEC 320-type input cordset approved for the country of use. Power to the unit is controlled by the front-panel Power switch.

An auxiliary AC “jumper” (pass-through) outlet is provided on the rear panel, and a ”jumper” power cordset is included, to simplify power connections by “daisy-chaining” together an array of AEW receivers and antenna distribution units. Maximum output from the auxiliary AC outlet is 500 watts; it is fused internally. Do not exceed the 500W power limit. Do not connect high-current devices, such as power amplifiers, to this outlet.

Rear Panel Controls and Functions (Fig. B)

Front-mount Antennas

BNC-to-BNC connectors and jumper cables are included with the unit to permit mounting antennas on the front panel.

•BNC-BNC through-panel connectors: Remove the nut and lock-washer from each connector. Install the connectors from the front into the two panel holes. Note that the flat on the threaded section must be aligned with the flat in each panel hole. Secure each connector from the back with its lock-washer and nut, tightening the nut firmly.

•BNC-BNC cable jumpers: Connect the jumpers to the rear antenna jacks first; then attach them to the BNC connectors on the front panel. Make certain the bayonet twist-rings are fully latched on the connectors at both ends.

4.CHANNEL “B” ANTENNA INPUT: Attach the “B” antenna here, or extend it with a low-loss antenna cable. (Antenna and cable not included.) The antenna input jack also is capable of providing +12V DC output on its center pin at up to 250 mA to power in-line RF devices.

5.CHANNEL “B” ANTENNA POWER SWITCH: Enables or disables +12V DC on the Channel “B” Antenna Input connector (#4).

6.CHANNEL “B” CASCADE OUTPUT: Directional coupler provides RF output to additional distribution systems operating in the same frequency band. Each cascade output should be connected to only one other unit’s input, and no more than three distribution units total should be “daisy-chained.”

7.CHANNEL “B” DISTRIBUTION OUTPUTS: Four jacks provide RF distribution to receivers operating in the same frequency band. Each output should be connected to only one other antenna input, without “daisy-chaining.” Unused outputs do not require termination.

8.CHANNEL “A” ANTENNA INPUT: See #4 above.

9.CHANNEL “A” ANTENNA POWER SWITCH: Enables or disables +12V DC on the Channel “A” Antenna Input connector (#8).

10.CHANNEL “A” CASCADE OUTPUT: See #6.

11.CHANNEL “A” DISTRIBUTION OUTPUTS: See #7.

12.DC OUTPUT JACKS: Provides 12V DC (center positive) at up to 500 mA from each jack to power receivers. Connect the included ATW-RDCN cables here to supply 12V DC to up to four ATW-R310 (or like-powered) receivers.

13.AUXILIARY AC OUTLET: An auxiliary AC pass-through outlet and included IEC “jumper” power cordset simplify making power connections to an array of AEW receivers and antenna distribution units. Maximum output from the auxiliary AC outlet is 500 watts; it is internally fuse-protected.

14.AC POWER INPUT: IEC-type connector for 100V–240V AC, 50/60 Hz power input. No adjustment for mains voltage/ frequency is necessary.

15.REAR RACK MOUNT: Mounts are provided at the rear of the side panels to permit attachment to rear rack rails in racks so equipped.
