Rear Panel Controls and Functions (Fig. B)
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 pro12V 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 di12V 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 di12V 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.
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.
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.
