Rear Panel Controls and Functions (Fig. B)
3.
AC POWER: IEC-type connector for 100V to 240V AC power input. No adjustment for mains voltage/frequency is necessary;
connect an IEC input cordset approved for the country of use.
4.
FUSE HOLDER: To check or replace fuse, disconnect the AC cordset and carefully remove the holder with a small
screwdriver. Replace fuse only with the same type 250V 2.5A.
5.
DC OUTPUT JACKS: Provides 12V DC (center
positive) at up to 350 mA from each jack to power receivers. Connect
the included ATW-RDCP polarity-inverting cables here to supply 12V DC (center
negative) to up to four ATW-R73
(or like-powered) receivers.
6.
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 pr12V DC output on its center pin at up to 250 mA to power
in-line RF devices.
7.
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 input, and no more than three
distribution units total should be “daisy-chained.”
8.
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.
9.
CHANNEL “A” ANTENNA INPUT: See #6 above.
10. CHANNEL “A” CASCADE OUTPUT: See #7.
11. CHANNEL “A” DISTRIBUTION OUTPUTS: See #8.
Accessories Included
1 120V power cordset, 10 BNC-to-BNC
1.5' interconnect cables, 4 ATW-RDCP
DC polarity-inverting 1.5' interconnect
cables, 2 rack-mount adapters
(installed), 4 self-adhesive feet.
Optional Accessories
ATW-RDCN:
Non-polarity-inverting DC
interconnect cables (set of four). For
use with receivers that have center
positive DC jacks.
ATW-RA1:
Rack-mount antenna kit
brings antenna inputs to the front of
unit for ease of setup, or when unit
is enclosed in a metal rack. Includes
a pair of adjustable-length antennas
suitable for UHF or VHF use.
