(unit 1), while the lower transmitter is
designated as transmitter B (unit 2). The
uncrated cabinet (with transmitters) weighs
approximately 75 kg (165 lbs). The cabinet
also contains:
- a type 'N' RF coaxial connector (J1),
which is used as the RF output
connection point for the RF feed cable
- an ac power duplex receptacle (J2)
- a dual transmitter interface assembly
(unit 3)
- a computer remote control unit (unit 4,
optional)
- interconnecting wiring
Refer to Figures 2 and 3 for electrical
schematics of the dual transmitter system.
Refer to Figures 4 through 6 for assembly
detail and dimensional information of the
NARB15 cabinet.
3. THEORY OF OPERATION
The theory of operation presented in the
ND500II instruction manual describes the
operation of both transmitters A (ND500II-
11x-x20) and B (ND500II-01x-x20). The
following provides a brief description for
transmitters that are connected in a
main/standby dual installation. See Figure
2A or 2B for interconnecting detail. See
Figure 3 for the electrical schematic of the
dual transmitter interface PWB (3A1).
3.1 Normal Operation: When the ‘main’
transmitter, selected by MAIN XMTR A/B
switch 3S2, is turned on and producing a
satisfactory RF output, the following will
occur:
(a) 15V will be applied from the main
transmitter (1A11J4-13 or 2A11J4-13),
through the dual transmitter interface
PWB (3A1J4-11 or 3A1J5-19) to the
standby transmitter (1A11J4-20 or
2A11J4-20), as the 'standby off' control
signal.
(b) If transmitter A is selected as the 'main'
transmitter, the main/standby relay in
transmitter A's harmonic filter will be
energized and will connect transmitter
A’s output to J1 (RF OUT) as the RF
output to the antenna system.
(c) If transmitter B is selected as the 'main'
transmitter, the main/standby relay in
transmitter A's harmonic filter will be de-
energized and transmitter B’s output will
be connected to J1 (RF OUT) as the
output to the antenna system.
(d) The selected 'main' transmitter will
provide 15 V and the manually
controlled slewing commands (ATU
CONT) for the antenna system's antenna
tuning unit via the dual transmitter
interface assembly (unit 3).

Issue 1.0 Information Sheet
(e) The selected 'main' transmitter will be
providing the 'audio out' (RMT AUD)
sample via the dual transmitter interface
assembly (unit 3).
(f) If transmitter A is selected as the 'main'
transmitter, an open collector SHTDN ALM
(B)signal will be applied to 3A1J5-23
from A11J4-17 ('shutdown') of
transmitter B.
(g) If transmitter B is selected as the 'main'
transmitter, an open collector SHTDN ALM
(A) signal will be applied to 3A1J4-23
from A11J4-17 ('shutdown') of
transmitter A.
3.2 Shutdown/Changeover: If the
selected 'main' transmitter is shutdown
because an abnormal condition was sensed
for more than 20 seconds (maximum pre-
settable time period is 80 seconds), or for
any other reason, the following will occur:
(a) The +15 V power supply in the selected
'main' transmitter will be switched off,
removing +15 V from A11J4-13 of the
main transmitter and from A11J4-20 of
the standby transmitter via the dual
transmitter interface assembly (unit 3).
The standby transmitter will turn on.
(b) If transmitter A is selected as the 'main'
transmitter, the main/standby relay in the
transmitter A's harmonic filter will de-
energize and route the 'standby' (B)
transmitter's output to J1 (RF OUT) as the
RF output to the antenna system.
(c) If transmitter B is selected as the 'main'
transmitter, the main/standby relay in the
transmitter A's harmonic filter will
energize and route the 'standby' (A)
transmitter's output to J1 (RF OUT) as the
RF output to the antenna system.
(d) The 'standby' transmitter will provide 15
V and the manually controlled slewing
commands (ATU CONT) for the antenna
system's antenna tuning unit via the dual
transmitter interface assembly (unit 3).
(e) The standby transmitter will be providing
the 'audio out' (RMT AUD) sample.
(f) If transmitter A is selected as the 'main'
transmitter, an open collector SHTDN ALM
(A)signal will be applied to 3A1J4-23
from A11J4-17 ('shutdown') of
transmitter A, causing a ground to be
applied to RMT CHGOV ALM outputs
3A1J1-8 and 3A1TB3-6, indicating the
standby transmitter is on.
(g) If transmitter B is selected as the 'main'
transmitter, an open collector SHTDN ALM
(B)signal will be applied to 3A1J5-23
from A11J4-17 ('shutdown') of
transmitter B, causing a ground to be
applied to RMT CHGOV ALM outputs
3A1J1-8 and 3A1TB3-6, indicating the
standby transmitter is on.
