These same operatingparameters may also be selectively
altered using various control switches located-on the
DMP.Also, two separate 7-segment displayunits indicate
(in hexadecimal notation =-$#) the current auxiliary
primary operating station channels ($1 through $F
Channell through 15,and $0 Channell).
1.2 DMP 4O-CONDUCTOR INTERFACE CABLE
The DMP comes with a separate 40-conductor ribbon interface cable, a separate 8-conductor metering cable with
"modular" connectors, two separate voltage probes and
a set of housing rods that may be extended and inserted
into the mounting rails inside the station cabinet. Refer
to Figure 2 for the locations of the connectors used for
the CONTROL (11201), METER (11202), + voltage
probe (11203), and - voltage probe (11204). Refer to
Figure 3 for a view of the DMP with its front panel re-
moved.
The 40-conductor interface cable connects the station
EXPANSION connector J800 (located on the top of the
control tray housing) to the DMP CONTROL connector
J1201. This cable provides interface lines which connect
power, audio and digital signals between the station control board, other control modules within the station, and
the DMP. There are four types of signal lines provided,
as follows:
•• audio line
., dedicated logic line
., multiplexed logic (MUXbus) lines
., power and ground lines
SELECT AUDIO (Pin 32) - Audio line
The Select Audio signal, originating on the station control
module, is the audio input for the local speaker amplifier
circuit in the DMP. Any of the following audio signals will
be present on the select audio line when it is properly
gated by the control circuits in the station: primary receiver audio, secondary receiver audio, transmit audio from
the remote wire line, and automatic station LD. and
alarm tone audio. The Select.Andio line is connected to
the wiper of the VOLUMpcontrol on the control tray
front panel. Therefore, the debias level and ac level on
the line vary depending onthe VOLUME control setting.
The DMP employs an audio power amplifier circuit to
provide up to 5watts of local service audio from the Select
Audio signal, through the DMP internal 4-ohm speaker.
The audio power amplifier circuit can be disabled with
SPEAKER ON/OFF switch S121O,located on the face of
the DMP. By connecting an optional microphone
(HMN1001) to CONTROL Jack J812 on the front panel
of the station control tray, the transmitter can be locally
keyed and modulated, or intercom with the remote control.console operator can be accomplished.
EXPANSION RE5ET (Pin

e.EXPANSION RESET signal is a shared logic line
12) -
Dedicated Logic line
whiChallows a clean, coordinated start up of the station
co:fltro1module and any other interconnected modules or
e~t~rnal equipment (such as the DMP). The EXPAN-
~QN RESET signal is active low at power-up, or when
station control module switch S801 is put into the TEST
position, or when t~ station control module is reset by
its watchdog timer circuit, or when another control module receives a command to reset the station. Also, normal
MUXbus operation is suspended while the watchdog timer circuit generated RESET signal is active low. The
MUXbus data strobe line DS, is held inactive and the
MUXbus address and data lines do not follow their normal patterns.
IMPORTANT
While the EXPANSION RESET line is
active low, no module except the station
control module should write to the MUXbus data lines. Otherwise, the station control module may fail its self diagnostic
tests, and remain reset indefinitely.
Multiplexed Logic (MUXbus) lines
The multiplexed logic (MUXbus) lines consist of the following signals:
* Four Address lines (BAO-BA3) - Pins 13-16
•• Four Data lines (BDO-BD3) - Pins 17-20
•• Data strobe (DS) - Pin 22
All DMP MUXbus lines are referenced to audio ground
(logic ground is not used). The four address and the four

data lines define 16 words of 4~bits each, or 64 total bits
as shown in Table 1. These bits form a multi-directional
digital communications path. The bus is multiplexed to
conserve interconnections (64 connections reduced to 9)
and to increase future expansion capability. The data
strobe and the four address lines are driven bythe
control module. The data lines are.inverted and open collector driven in both the station control module and the
DMP. This allows the station control module and the
DMP to drive the same bit in a nondestructive, wired
"OR" fashion.
The MUXbus timing diagram is shown in Figure 4. The
address lines are incremented once, approximately every
310microseconds. The address changes when data strobe

The proper indications are the same as those obtained using a Motorola Portable Test Set or TEK-5F Meter Panel,
as described in the MSF5000 Base Station and Repeater
Instruction Manual. A specific meter position is selected
by using the METER selector switch S1208 on the face of
the DMP. When METER selector switch S1208 is in the
"10 V" or "25 V" position, the meter monitors the voltage probes and is calibrated to read full-scale voltage (in-
stead of full-scale microamperes).
IMPORTA.NT
When measuringthe.power amplifier circuits, via J503, meter REVERSING switch
S1209 must be placed in the "-" (or re-
verse) position. METER REVERSING
switch S1209 is normally in the"
+"
(or
forward) position when the DMP is con-
nected to either J413 or J210 (TX or RX
Metering, respectively).

1.3 DMP 8-CONDUCTOR METERING CABLE
The 8-conductor metering cable connects the DMP METER Jack J1202 to either the station TX Metering or station RX Metering Jack. The TX and RX Metering Jacks
(J413 and J21O, respectively) are both located on the station RF Tray front panel. The PAMetering Jack (J503) is
located on the PA Distribution Board, within the station
Power Amplifier Deck. This cable provides interface lines
which connect five metering lines and a meter common
line to the DMP, as shown in Table 2.
1.4 VOLTAGE PROBES
The two voltage probes plug into two jacks provided on
the bottom edge of the DMP: RED =

with a reversible blunt or pointed tip.
2. METERING FACILITIES
The DMP provides a measured indication for the signals
listed in Table 2 on a 0-50
J.l.A
full-scale meter (MI201).
3. DIAGNOSTIC FACILITIES
3.1 GENERAL
The right hand portion of the DMP contains the switches
and displays required to monitor and manipulate the operating parameters of the station. These functions are
made possible by connecting circuits of the DMP to the
MUXbus of the station EXPANSION connector (J800).
3.2 CHANNEL DISPLAY
The CHANNEL display consists of two 7-segment LED
packages that are used to display the station's current aux-
iliary operating channel (left-most unit) and its current
primary operating channel (right-most unit). The primary
operating channel is the channel currently selected for
the station transmitter and primary receiver. The auxilia-
ry
channel may have several uses, one of which is that it
would be the selected channel of the secondary receiver
in a 2-receiver station. The operating CHANNEL display
changes each time the station changes operating channel,
or the operating channel is changed via the channel select
switch on the station control tray. The auxiliary CHANNEL display changes only when a change of operating
channel occurs.

3.3 STATUS DISPLAY
The Station Parameter Status Display Matrix consists of
eight 8 element LED packages located behind the re-
cessed sceened panel of the DMP. The screening identifies each of 641vlUXbus bits, via a specific mnemonic designation, as shown in Thole 1.
The STATUS DisplaY.Pl"()vides a visible indication of the
major portion of the main control related activities that
are occurring at any timejn. the station. These include various push-to-talk signals, the state of the squelch circuits,
the presence of properly coded squelch signals, the station channel, the station-level alarms and "wild" card
functions, as well as specialized activities such as Chan-
nel-Scan or DVP operation.
NOTE
To check to see if all the LEDs in this section of DMP are functional, momentarily
switch the ENIER DATA-TEST switch to
the TEST position. AU 64 LEDs in the
STATUS display area should light, and the
two-digit CHANNEL display should indi-
cate $FF.
The STATUS Display indicates the active control conditions within the station with a corresponding illuminated
LED. The absence of an expected condition can be readily
observed as the station is operated, leading to rapid identification of a defective area.
An active condition is also cleared when the ADDRESS
switch is moved to a different address, and the ENTER
DATA switch is used to activate a MUXbus bit at the new
address.
For example, suppose it is desired to verify that the proper
alarm tones would be sent by the station in the event of
a PA failure. To simulate this alarm condition using the
DMP, set the ADDRESS switch to 12 (the row containing
the PA alarm signal) and flip the data switch up (for the
column containing this signal (D1). Flip the ENfER
DATA switch, illuminating the LED in the status display
for PA alarm and activating a simulated PA failure alarm.
If the station is working properly, two beeps will be heard.
If the Dl switch is turned to the OFF position and the EN-
TER DATA switch is activated, the PA alarm LED will
tum off, and the alarm beeps will cease. Likewise, if the
ADDRESS switch is moved to address 1, and the D1
switch is left in the up position, then when the ENTER
DATA switch is activated, the PA alarm LED will turn off,
the alarm beeps will cease, the LOCal PTf LED will illuminate, and the station will key up.
NOTE
"Status only" bits, when activated by the
DMP, will cause their corresponding LED
to light, but will not affect a change in station operation. The station causes these
LEDs to light when it has successfully accomplished a certain function.
4. MUXBUS BIT DEFINITIONS
To simulate an active condition in the station using the
DMP, select the address or row in the display containing
the particular signal with the ADDRESS switch. Next, set
one of the data switches DO through D3 corresponding to
the column in the display containing the signal. Momen-
tarily switch the ENTER DATA-TEST switch to the ENTER DATA position and the condition will become active. To clear the condition, return the data switch to the
OFF position and flip the switch to the ENTER DATA
position once again.
CAUTION
It is recommended that the DMP be disconnected from the control tray (via J8oo)
during station power up. This prevents the
station from being initially activated in a
possible undesirable function. However, if
the station is powered up with the DMP
connected, and an undesirable condition
does occur, place the four DATA switches
to the OFF position, and then toggle the
ENTER DATA switch. This will deactivate
the four DMP data bits applied to the
MUXbus Data Line and remove the undesirable condition
4.1 INTRODUCTION
The following paragraphs provide definitions for each of
the 64 operating parameters (MUXbus Bits) displayed by
the DMP. Each of these bits may have their state changed
by the DMP. Each paragraph title gives the MUXbus Bit
mnemonic, definition, and row-column address required
for access (in the form: #, D#), respectively.
4.2 SP XMIT (SPECIAL TRANSMIT) 0, D3
The SP XMIT bit indicates that the deviation and/or the
rf PA power should be either boosted or cut, defined by
information in the station control module code plug. The
default condition in the station control module code plug,
upon activation of this MUXbus bit, is deviation control.
This bit will only have an effect during a PIT. The activation of this bit, by itself, will not key the station.
4.3 SCAN (SCAN ENABLE) 0, D2
The SCAN bit forces the station control module to enable
the primary receiver as a scanning receiver. The station
must be ordered with the Channel-Scan option in order
for this feature to operate. Only the primary receiver can
scan.

4.4 T ALM DS (TOTAL ALARM DISABLE) 0, Dl
The T ALM DS bit mutes all alarm tones until this bit is
deactivated. This bit will deactivate the station control
module alarm bits on the Reverse "Wild Card" bits 1
through 4, but will not affect the other Reverse "Wild
Card" bits on the MUXbus. Pulsing T ALM DS for 25
msec or longer will release S ALM DS, if active.
active. LIN PTT stays active if a higher-priority PTT is active. LIN PTT is inactive when RBITOC is encoded, unless the RBITOC is caused by the Line PT T TOT timing
out. If the station is so equipped, LIN PTT switches the
antenna switch to its transmit state. Line, Local, and Repeater PTT priorities are set for each channel by station
control module code plug qualifiers
4.8 LOC PTT (LOCAL PVSH- TO-TALK) 1, Dl
4.5 S ALM DS (SELECTIVE ALARM DISABLE) O,DO
The S ALM DS bit is meant to support a "nuisance avoidance" alarm feature. The console operator can mute inprogress alarm tones without fear of missing any new
alarms. For example, initially all alarm bits (Reverse
"Wild Card" bits, addresses 12 & 13) and S ALM DS are
inactive. An alarm condition activates an alarm bit, and
alarm tones are heard. The wireline control pulses
S ALM DS active for 25 msec or longer in response to a
remote control console command, and the alarm tones
are muted. If the alarm condition were to disappear, the
corresponding alarm bit would be deactivated, S ALM DS
would be cleared, and no alarm tones would be heard
since no alarm bit is active. If, instead, a second alarm bit
were activated while the first alarm was active, S ALM DS
would be deactivated and alarm tones for both alarms
would be heard. The wireline control could re-enable
S ALM DS, then alarm tones for both alarms would be
muted. S ALM DS does not deactivate the MUXbus
alarm bits, but merely mutes the alarm tones.
4.6 RPT PTT (REPEATER PUSH-TO-TALK) 1, D3
The RPT PTT bit keys the transmitter, modulating with
RX 1 Audio if no higher-priority PTT is active. If a high-
er-priority PTT is active, the station control module deactivates RPT P1T. If the repeater PTT time-out timer
(TOT) times out, RPT PTT will be deactivated, and the
transmitter will dekey. If repeater knock down (RPT KD)
goes active while RPT PTT is active, RPT PTT will be
deactivated, PL reverse burst or DPL turn off code
TOC) will be encoded if appropriate, and the transmitter
will dekey. RPT PTT is active during repeater drop-out
delay. RPT PTT is inactive when RBITOC is encoded.
The station control module turns on RPT P1T, if repeater
audio activity exists on Receiver 1, and if RPT KD is inac-
tive, and if no higher-priority PTT is active. "Repeater
audio activity" is set for each channel by station control
module code plug qualifiers. These qualifiers determine
what combination of the four MUXbus bits RX P L DS,
Rl PL DT, RPT USQ, and AUX DET are ANDed to ob-
tain RPT
are set for each channel by station control module code
plug qualifiers.
4.7 LIN PTT (LINE PUSH-TO-TALK) I,D2
PTf.
Line, Local, and Repeater PTT priorities
(RBI
The LOC PTT bit keys the transmitter, modulating with
Local Audio if no higher priority PTT is active. LOC PTT
says active if a higher priority PTT is active. LOC PTT is
inactive when RBITOC is encoded, unless the RBIT OC
is caused by the Local PTT TOT timing out. If the station
is so equipped, LO C PTT switches the antenna switch to
its transmit state. LOC PTT is active if the PTT switch is
depressed on the local microphone plugged into the station control module front panel CONTROL connector
J812. Line, Local, and Repeater PTT priorities are set for
each channel by station control module code plug qualifiers. The front panel XMIT switch on the station control
module will activate TX PL DS and key the station without activating the LOC PTT bit on the MUXbus. This key
will be without PL, DPL, or audio (silent carrier). As
thusly defined,itis not a true P1T, and can be overridden
by any other PTT
4.9 INTCOM (INTERCOM) 1, DO
The INTCOM bit is active if the remote control module
INTERCOM switch is actuated. When INTCOM is active, the station control module treats LOC PTT as an Intercom P1T. Local Audio is gated to the wireline (out-
bound wireline) when a local PTT is generated, but the
transmitter is not keyed. When LOC PTT is not active,
remote control console audio (inbound wireline) is gated
to the 112-watt local audio amplifier.
4.10 TX PL DS (TRANSMIT PLIDPL DISABLE) 2, D3
The TX PL DS bit mutes encoded PL or DPL. The Trans-
mit PL Strip wireline option utilizes this bit. If PL or DPL
is being encoded when TX PL DS goes active, then
TOC will be generated before muting PL or DPL. This
bit will also be set active whenever PLI DPL encoding is
disabled, such as during an auto ID transmission, or if the
front panel XMIT switch on station control module is activated.
4.11 TX ACT (TRANSMITTER ACTMTY) 2, D2
The TX ACT is a status only bit, and indicates that the
transmit rf channel (outbound) is ready. TX ACT goes active after a keyup, when the transmitter power output has
stabilized. In the event of a PA failure on keyup, TX ACT
stays inactive (doesn't glitch). TX ACT goes inactive
when the station control module dekeys the PA. TX ACT
is inactive during RBITOC.
4.12 RX2 ACT (RECEIVER 2 ACTMTY) 2,
RBI
m
The LIN PTT bit keys the transmitter, modulating with

68P81114E03
The RX2 ACT bit indicates whether second receiver audio should be used. The second receiver control module
7/15/90
Page 7
responds to an active RX2 ACT by gating deemphasized,
PL-stripped audio from the second receiver to the RX2
audio line. From there, it is mixed with line audio (outbound wireline) by the station control module. RX2 Audio is also mixed with select audio (local speaker) by the
station control module.
audio (outbound wireline) and select audio (local speak-
er) lines. The attenuation is accomplished by means of a
potentiometer on the second receiver control module.
Therefore, RX2 audio can be fully muted, if desired.
4.19 R2 PL DT (RECEIVER 2 PLlDPL DETECT) 4, D2
4.13 RX1 ACT (RECEIVER 1 ACTMTY) 2, DO
The RXI ACT bit indicates whether the primary receiver
has audio present with the proper qualifiers to unmute receiver audio. This condition is set for each channel by four
qualifiers in the station control module code plug. These
qualifiers determine what combination of the four MUX-
bus bits RX PL DS, Rl PL DT, Rl UN SQ, and AUX DET
are ANDed to obtain RXI ACf. The station control module responds to an active RXI ACT by opening the RXI
audio gate. This gates RXI audio to both the line audio
(outbound wireline) and select audio (local speaker) lines.
RXI audio is also gated to the station control module repeater audio gate. If the station is transmitting due to a
RPT PTT, then the repeater audio gate will be open and
RXI audio will be gated, via the IDC circuit, to the TX
modulation audio line.
4.14 RX PL DS (RECEIVE PLIDPL DISABLE) 3, D3
The RX PL DS bit causes the station to revert to carrier
squelch only operation for purposes of determining status
of RXI ACT and RX2 ACf. The Monitor and Receiver
Squelch OnlOff wireline functions utilize RX PL DS.
Also, the station control module front panel PL Disable
switch activates RX PL DS.
4.15 Rl PL DT (RECEIVER 1 PLlDPL DETECT) 3, D2
The Rl PL DT bit is active when PL or DPL coded
squelch is being detected via Receiver 1.
The R2 PL DT is active when PL or DPL coded squelch
is being detected via Receiver 2.
4.20 R2 SQ LV (RECEIVER 2 SQUELCH LEVEL) 4, D1
The R2 SQ LV bit changes the carrier squelch threshold.
When R2 SQ LV is active, the second receiver is operat-
ing with "loose" squelch.
4.21 R2 UN SQ (RECEIVER 2 UNSQUELCH) 4, DO
The R2 UN SQ bit is a status only bit, and is active when
the Receiver 2 audio carrier squelch circuit on the second
receiver control module detects activity. R2 UN SQ is
used for audio gating (refer to RX2 ACT). The second receiver can neither key the repeater (activate RPT
nor modulate the transmitter.
4.22 GD TN DT (GUARD TONE DETECT) 5, D3
The GD TN DT bit becomes active whenever high level
guard tone is detected from the TX Audio signal (inbound
wireline) by the tone remote control module. In stations
with an antenna switch, the station control module re-
sponds to an active GD TN DT by switching the antenna
switch to its transmit state. The TX Audio signal is muted
(on the station control module) while GD TN DT is active, in order to prevent remote control tones from being
transmitted.
4.23 AUX DET (AUXILIARY DETECT) 5, D2
PIT),
4.16 Rl SQ LV (RECEIVER 1 SQUELCH LEVEL) 3,
The R1SQ LV bit changes the carrier squelch threshold.
When Rl SQ LV is active, the primary receiver is operat-
ing with "loose" squelch.
4.17 Rl UN SQ (RECEIVER 1 UNSQUELCH) 3, DO
The Rl UN SQ bit is a status only bit, and is active when
the Receiver1audio carrier squelch circuit on the station
control module detects activity. Rl UN SQ is used for audio gating (refer to RX1ACT), not for repeater keying
(refer to RPT
4.18 R2 MUTE (RECEIVER 2 MUTE) 4, D3
The R2 MUfE bit causes the second receiver control
module to attenuate the audio driving the RX2 audio line,
so that Local or RXI audio can be heard on both the line
7/15/90
PIT).
nt
68P81114E03
The AUX DET bit indicates that an optional decoder is
detecting. The optional decoder may be connected to either Receiver1or Receiver 2 audio. AUX DET can be
used to activate TXl ACT , RX2 ACT, and RPT
a manner similar to the Rl PL DT and Rl UN SQ qualifiers.
4.24 RPT KD (REPEATER KNOCK-DOWN) 5, Dl
The RPT KD bit disallows a repeater PTT. Also, this bit
forces an existing active RPT
4.25 RPT USQ (REPEATER UN SQUELCH) 5, DO
The RPT USQ bit is a status only bit, andisactive when
the Receiver1repeater carrier squelch circuit, located on
the station control module, detects activity. This bit

4.26 ACC DIS (ACCESS DISABLE) 6, D3
The ACC DIS bit is a status only bit, and is active when
the Access Disable station control module switch is actu-
ated. ACC DIS active indicates that the following five
functions are inhibited: 1) Auto ID; 2) Alarm tones; 3)
Time-out timers;4)Repeater
mary receiver; and, 5) Wire line commands including Line
P1T. When Access Disabled, the station operating channel is selected with the CHANNEL select switch, located
on the front panel of the remote control module. The previous station operating channel is "remembered" by the
station control module and reinstated when the Access
Disable switch is deactivated. If there is no remote control
module connected as part of the station (repeater only operation) the DMP channel display will show
station control module will equate this with Channell operation.
4.27 EX DA DT (EXTERNAL DATA DETECT) 6, D2
The EX DA DT bit, when active, can cause the station
control module to mute TX, and/or local, and/or RXI
(Repeater) audios, under code plug programming control. This bit can allow or disallow selected mixing of these
audios with TX data audio onto the TX modulation audio
line. Which of the three audios is muted depends on
which PTT is keying the transmitter. The intent is to op-
tionally prevent audio from mixing with TX Data audio.
Whether or not mixing occurs is determined by a qualifier
for each channel in the station control module code plug.

and
AUX C8, AUX C4, AUX C2,&AUX Cl
(AUXILIARY CHANNEL)9,D3 TURU9,DO
These eight bits determine up to two sets of channels for
the station. A channel is a station state which chooses predefined groups of station parameters such as transmit and
receive frequencies and coded squelch code. The channel
parameters are defined in the station control module
code plug. Also, the station control module code plug
contains the transmit, primary receive, and Channel-Scan
parameters. The (second receiver control module) code
plug contains the second receiver parameters. The TX/
RX Channel occupies Address 8, Bits 3-0. The Auxiliary
Channel (Second Receiver and Channel-Scan) occupies
Address 9, Bits 3-0. Optionally, the bits making up the
two channels can be re-grouped to form two different
channels, in which one channel has more. than four bits.
In this optional configuration, the TX/RX Channel least
significant bit (LSB) is at Address8,BitO.If more than
four bits are required to form the TX/RX channel representation, then those bits are taken from the auxiliary
channel assignments beginning with bit 0 of address 9.
The Auxiliary Channel then starts (LSB) with the next
available bit after the last defined TX/RX channel bit and
continues to bit 3 of address 9. If the two channels are to
be independent, then they cannot share any bits. This
means that the sum of the numbers of bits for the two independent channels must be eight or less.
4.28 DW SEL (DIGITAL VOICE PROTECTION

The DVP SEL bit selects either the primary DVP code
or the secondary DVP subcode from the DVP control
module.
4.29 DW C/C (DIGITAL VOICE PROTECTION
CODED/CLEAR) 6, DO
The DVP C/C bit, when active, enables the encryption
and decryption functions of the DVP control module.
Therefore, voice is transmitted "coded". When inactive,
this bit disables the encryption and decryption functions.
Therefore, voice is transmitted "clear".

4.33 REVERSE "WILD CARD" PARAMETER BITS
Use of the reverse "wild card" bits (8 bits total, addresses
12 &
13)
requires the "wild card" module which resides
in the Control Option Tray. The "wild card" inputs (four
per card) activate or deactivate the appropriate Reverse
"wild card" MUXbus bit in response to a status signal external to the station. The eight reverse "wild card" MUX-
bus bits also have an additional definition. They are con-
sidered alarms which, when activated, translate to alarm
tones and are sent to the remote control console via the
outbound wireline. Optionally, the alarm tones may also
be transmitted. The alarms are tone bursts (beeps). The
four bits in Address

itors cause the station control module to write to these
bits which, in tum, send the alarm tones.
NOTE
If the four internal alarm bits of address 12
are activated by the DMP, or some other
control module connected to the MUXbus, then the alarm beeps will be activated,
but the actual internal alarm condition will
not be simulated. For example, if the PA
Fail alarm bit (RW2 PA) were to be activated, two alarm beeps would be sent, but
the PA itself would not be forced to dekey.
The station control module code plug contains information
which determines whether an internal alarm gets written to
the MUXbus, and also if all of the reverse "wild card"
MUXbus bits will be enabled to activate alarm tones. Thus,
all 8 bits can be configured as external alarm inputs, if desired. The maximum number of internal alarms is four.

failed. A successful keyup or a station control module reset
is required to clear the alarm. The alarm may be active when
the transmitter is de-keyed, due to a prior failure. PA Fail
means that one or both of the station control module PA
status lines (pA On or PA Full Power) are inactive
msec after the start of a keyup, or for
ously during keyup, thereafter. RW2 PA is not activated by
the station control module if the PA is not keyed at full pow-
er due to the station control module personality EPROM
rf power cut option. If the station control module service
jumper (JUB01) is installed, the station control module will
activate RW2 PA regardless of the PA status lines. This is
a reminder that the rf power amplifier is operating in a nonstandard manner.
RWl BAT
DO
This bit is the battery revert internal station alarm parameter activated by the station control module. RWI BAT is active when the station battery charger power supply indicates
that the station has lost ac power and has switched to emergency battery backup. RWI BAT becomes inactive as soon
as proper ac power is restored to the station.

Use of the Forward "Wild Card" bits (up to 8 bits on addresses 14&15) require the "wild card" module (four outputs per card) which resides in the Control Option Tray. Remote wireline control activates these bits. The "wild card"
control module responds by activating a relay closure or an
open collector output. These closures and/or outputs can
then be used to control equipment external to the station.
