GENERAL INFORMATION
Midian’s TRC-400 is a tone remote controller with Harris’ G-Star ANI and ENI display decoding with dialing
capabilities in DTMF, 5-Tone, Pulse Tone and 2-Tone. The TRC uses EIA and Industry standards for monitor,
guard, and F1-F16 function tones. Midian also adds F17 for additional function control when used with Midian’s
TTC-1. The built-in display shows the frequency/function selection, real-time clock and the decoded ANI/ENI with
Alias.
The TRC comes standard with an internal microphone and speaker. A gooseneck microphone (TRC Option A) or
handset and cradle (TRC Option C) are also available. The standard configuration is for a 2-wire and single line
system. A 4-wire option (TRC Option F) or a Line 2 option (TRC Option E) is available for these types of systems.
Midian’s TRC can be used with Midian’s TTC-1, tone remote adaptor, or another manufacturer’s tone remote
adaptor that uses EIA and industry standard F1-F16 function tones.

HARDWARE INSTALLATION
Be certain to follow standard anti-static procedures when handling any of Midian’s products.
Getting Started:
The TRC has a number of adjustment potentiometers and configuration jumpers. These have been adjusted and
configured at the factory for a typical installation. However, audio levels should be verified and adjusted (if
necessary) at the time of installation. Also, the configuration jumpers should be inspected prior to installation to
verify that they are in the right configuration. Jumper descriptions appear in the jumper settings section with a
quick reference table.
Line Interface
The line interface connector PL1 is a 10-pin RJ-45 style connector in the center of the back panel. A standard 4-
pin RJ-11 cable will plug into the RJ-45 and connect to the center 4-pins that are needed for 2-wire or 4-wire
interfaces. The remaining 6 pins are for use with a telemetry radio or microwave E&M options and for future
interoperability options.

Supervisor Operation: When using the supervisor option (TRC Option E), the supervisor TRC is connected to
the line via pins 2 and 3. The remaining TRC’s pins 5 and 6 are connected in parallel to the supervisor’s TRC pins
4 and 7. To enable these remotes, the supervisor relay must be engaged by pressing the * and # keys
simultaneously.
Diagram 3.3 – Supervisor Wiring
Telemetry Radio: Rather than connecting the TRC to a dedicated line to communicate with the tone remote
adaptor, telemetry radios can be used for communication. If connecting to a telemetry radio connect PL1 as
follows to the radio:
PL1-3: PTT Output: Connect to the PTT of the radio. Jumpers JP210 1-2 and JP208 1-2 should be installed.
PL1-6: TX Audio Output: Connect to the mic-hi input of the radio. Install JP205 2-3.
PL1-7: RX Audio Input: Connect to a point in the radio providing flat receive audio. Install JP11 1-2 & remove
JP204.
PL1-9: Battery: 15 volts through a 100 Ohm current limiting resistor (R216).
PL1-10: Ground: Connect to the ground of the radio.
Microwave: Connect the 4-wire audio to the TX and RX sides of the microwave. If the M lead is desired install
JP208 1-2 and JP10 1-2. Connect the microwave’s M lead to PL1 Pin 3 for an open collector to ground. If using
an external relay to control the microwave’s M lead you may use Q205 to provide 12 volts and install JP207 1-2
and JP208 2-3.

HARDWARE ALIGNMENT
The following procedures assume a good quality dedicated line is being used and the tone remote adaptor is already
installed. The alignments are preset at the factory and should not need to be adjusted during installation. However, if an
adjustment is needed please follow the procedures below.
RX Input Line Level Adjustment:
1. With the dedicated line connected to the TRC, connect a line level meter to the red and green (or yellow & black
with the 4-wire option) in bridging mode. If testing on a bench with no tone remote adaptor available use termination
mode on the line level meter.
2. With the line level meter generating Low-Level Guard Tone at -20 dBm, monitor TP304 with an oscilloscope.
3. Adjust RP306, so that 200 mV p-p is seen at TP304 or 165 mV p-p is seen at TP301. If paralleling multiple remotes,
this alignment should be done with all remotes attached.
TX Output Line Level Adjustment:
1. With the dedicated line connected to the TRC, connect a line level meter to the red and green in bridging mode. If
testing on a bench with no tone remote adaptor available use termination mode on the line level meter.
2. Set RP201 to 90%.
3. Push and hold the SEND key on the TRC to generate the Low-Level Guard Tone.
4. Adjust RP202 so that the line level meter shows the Low-Level Guard Tone at -20 dBm. If paralleling multiple
remotes, this alignment should be done with all remotes attached.
RX Notch Filter Alignment:
1. Generate the 2175 Hz Low-Level Guard Tone to the TRC.
2. Turn RP303 fully clockwise.
3. Monitor TP303 with a Sinadder. The sensitivity of the Sinadder should be adjusted to hear the tone.
4. Adjust RP302 until the tone is at it’s most diminished point.
5. Adjust RP303 until the tone fully diminishes.
6. Repeat steps 4 and 5 until no tone remains.
TX Notch Filter Alignment:
1. Unplug the internal microphone from the TRC, install JP101 1-2 and turn RP102 fully clockwise.
2. Push and hold the SEND key on the TRC to generate the 2175 Hz Low-Level Guard Tone.
3. Monitor TP103 with a Sinadder. The sensitivity of the Sinadder should be adjusted to hear the tone.
4. Adjust RP103 until the tone is at it’s most diminished point.
5. Adjust RP102 until the tone fully diminishes.
6. Repeat steps 4 and 5 until no tone remains.
7. After aligning the TX notch filter, remove JP101 and plug back in the internal or gooseneck microphone.
7

Handset Ear Level (TRC Option C Only):
1. With a field radio talking on channel to the TRC, adjust RP304 to a comfortable level.
Harris’ G-star Decode Level Alignment:
The PLL comes adjusted from the factory. However, in the event it becomes necessary to readjust the phase-lock loop,
perform the following steps:
1. Ground TP506.
2. Monitor TP505 and adjust RP503 for 18 kHz.
3. Remove the ground from TP506
4. Monitor TP505 and adjust RP502 for 25.6 kHz.

Freq: 01 Fire 1
PWR - LINE/SUP SEND - F1/F2
ABC
2 DEF 3 1 FREQ INTER
Power/Volume Switch: On the right side of the TRC, there is a switch which acts as the power and volume
switch. The switch is in the power off position when turned fully clockwise past the click. Turning the switch
counter-clockwise past the click turns the power on to the volume control. At this point the volume is in the low
position. Turning the switch further counter-clockwise increases the volume.
LCD: The 2-line LCD displays the time and unit ID on the first line and the frequency selection and frequency
alias on the second. When a dialing sequence is performed the second line is cleared and the dialing sequence is
displayed. Channel changes are also shows between parallel remotes.
LED 1 (PWR - LINE/SUP): This LED is a bi-color LED. The LED will glow red when the power is on to the TRC. It
glows orange when Line 2/Supervisor mode is active.
LED 2 (SEND - F1/F2): This LED is a tri-color LED. The LED will glow red during transmit of Freq 1 and orange
during transmit of Freq 2. It glows green when Guard Tone is detected from a parallel tone remote.
FREQ: The FREQ button acts as the frequency select and the function select key. Pressing this key followed by
0-17 will select the associated frequency or function. When using the TRC with Midian’s TTC-1 tone remote
adaptor both frequency and function tones are available. When using the TRC with another manufacturer’s tone
remote adaptor the frequency tones are selectable.
INTER: Pressing the INTER key will allow intercom communications between several connected tone remotes
without transmitting over the radio. When the INTER key is pressed and held, the audio is routed on the line
without the Guard Tone activating the transmitter. Other tone remotes on the same line will hear the audio
automatically. No cross mute is available in intercom mode since there is no Guard Tone present.
MONITOR: Pressing the MONITOR key will allow the user to monitor the channel before pressing the SEND key
to make a call. If a conversation is heard then another co-channel user presently “owns” the channel and should
not be interrupted.

OPERATION
The TRC has 4 operating modes:
Control Mode: This is the normal operating mode. It allows for remote control of a base station equipped with a
tone remote adaptor such as Midian’s TTC-1.
ANI Review Mode: This mode is for viewing the last 10 ANI’s stored in the ANI log.
Call Mode: This mode is for encoding DTMF, 5-Tone, 2-Tone or Pulse Tone.
Menu Mode: This mode is for configuring the TRC programmable features.
Control Mode:
In Control Mode the LCD display the time and ID of the last ANI received on the first line. On the second line the
selected frequency is displayed along with the programmed alias for that channel. If using with other Midian
TRC’s (revision G and higher), the paralleled remotes will also show the channel change on the display.Note:
Upon decoding of an ANI the LCD will toggle briefly between Control Mode and ANI Review Mode.
12:00 ID: 1234
Freq: 01 Fire 1
Frequency versus Function: The F1-F17 tones are referred to, industry wide, as Function Tones, but are used
as frequency selector tones to control the base station radio channel selection. Midian, with it’s TTC-1 tone
remote adaptor can use the Function Tones for either frequency selection or for controlling a function for remote
monitoring and control. These functions can be used for turning on/off a scrambler in the TTC-1, controlling voice
prompts from the TTC-1, or providing outputs from the TTC-1 to the TTC Option A (wild card module) for remotely
controlling equipment. If using the TRC with the LCD Option (TRC Option I) the TRC will display the Frequency
and the Function. For example, Frequency 1 can be selected while controlling Function 5 and the display will
show “Freq: 01 Func: 05”. A frequency and function should not share the same Function Tone. For example, if
only channel 1 and 2 at the base station need to be controlled (F1-F2), this leaves F3-F17 for use as function
control. If 16 channels need to be controlled at the base station (F1-F16), this leaves F17 for use as function
control.
Frequency Selection: To change the channel of the radio (F1 up to F16), press the FREQ button followed by a
single digit number for F1-F9 or a double digit number for F01-F16. When the Function Tone is selected, the TRC
sends the High-Level Guard Tone followed by the selected Function Tone to the tone remote adaptor to change
the channel of the radio. If using with other Midian TRC’s (revision G and higher), the paralleled remotes will also
show the channel change on the display.
Function Selection: To control a function press the FREQ button followed by a single digit number for F1-F9 or a
double digit number for F10-F16. When the Function Tone is selected, the TRC sends the High-Level Guard Tone
followed by the selected Function Tone to the TTC-1 to command the function control. Note: The selection of a
function does not cancel any frequency selection. If the TRC is on Frequency 1 and Function 5 is selected, the
tone remote adaptor will remain on Frequency 1.
Transmitting: After selecting the desired Function Tone for frequency selection, pressing and holding the SEND
key will generate the High-Level Guard Tone followed by the continuous Low-Level Guard Tone. The user speaks
into the microphone of the TRC and the voice goes out over the Low-Level Guard Tone.
12

Monitor: Prior to transmitting or dialing, the user should Monitor the channel to see if there is activity on the
channel. If there is activity, the user should wait until the channel is clear. Pressing the MONITOR button sends
the High-Level Guard Tone followed by the Monitor Function Tone to the tone remote adaptor giving it a
command to open the squelch of the radio. Depending on the tone remote adaptor this can be momentary or
latched. If momentary, the tone remote adaptor will close the squelch of the radio after a set amount of time. If
latched, the squelch will remain open until the tone remote adaptor receives a second Monitor command from the
TRC.
Receiving: When a field radio keys up, the tone remote adaptor passes the voice down the line to the TRC. The
voice will then be passed through to the internal speaker of the TRC.
Line 2/Supervisor Capability (* + #): If the TRC is ordered with TRC Option E, then the TRC is equipped with
the Line 2/Supervisor Capability. Line 2 is used for toggling between 2 different base station radios and
Supervisor is used to shut down any paralleled remotes. Pressing the * and # keys simultaneously activates the
Supervisor or the Line 2 mode depending on the options installed in the unit. Pressing the keys again deactivates
the Supervisor or the Line 2 mode. When activated LED 1 changes from red to orange.
Memory Dialing: The TRC supports up to 9 memory dials (1-9). Press and release the * key, followed by the
desired 1-9 number key for 1 second.
Last Number Redial: The TRC can recall the last sequence dialed by pressing and releasing the * key followed
by the SEND key.
ANI Review Mode:
Pressing FREQ and INTER at the same time while in Control Mode will change the mode to ANI Review Mode. In
this mode, the ANI is shown first on the first line followed by the timestamp. The second line shows the alias of
the decoded ANI, if programmed.
1234 12:00
< John Smith >
When ANI Review Mode is brought up the last incoming ANI is shown first. Pressing the FREQ scrolls the log to
the next most recent ANI in the log. Pressing INTER scrolls the log to the newer entries in the ANI log. When
there are additional older ANI’s to be displayed then the < icon is shown to the left. When there are additional
newer ANI’s to be displayed then the > icon is shown to the right.
If the status feature is enabled and a status is received with the ANI, then the ANI will alternate every 2 seconds
between the ANI and the status message.
To return to the Control Mode press FREQ and INTER simultaneously or press the CLR # key.
Call Mode:
To enter call mode press the MENU key and CALL will be displayed on the LCD. Press the SEND key to select
the CALL function.
Direct Dialing: Once in the call mode as above, simply press the numeric keys of the desired dialing sequence
and press SEND.
Database Dialing: Once in the call mode as above, simply press the INTER key to scroll right through the
database until the desired ID is found. Once found, press the SEND key. If while scrolling the desired ID is
passed by, press the FREQ key to scroll left.
13

Speed Dialing: Speed dialing can be done in the Control Mode or ANI Review Mode. The speed dials (or
memory dials) are set up in the Menu Mode of this manual. The TRC can have 9 speed dial memory locations set
up in memory, which are associated with the 1-9 keys. Press and release the * key and the press and hold the
desired 1-9 key for 1 second and the unit will automatically dial the associated speed dial.

Navigating the Menus
Press the key MENU key while in Control or ANI Review Mode to place the unit into Menu Mode. Upon entry to
Menu Mode, you will be in the Main Menu. The top line of the display indicates this. The bottom line displays an
item available for selection. When MENU is first selected the first available selection is for the CALL command.
The FREQ and INTER keys become scroll keys just as they do in ANI Review Mode. The scroll right symbol on
the right side of the display indicates that additional items are available. Press the INTER (SCROLL >) key to view
the next available item. The scroll left symbol will then appear, indicating that the FREQ (SCROLL <) key may be
used to go back to the previous item.
To select the displayed item, press the SEND key (the SEND key is the ENTER key in menu mode). Upon
selection, the name of the item will appear on the top line of the display. The bottom line will present additional
items for selection. Press the CLR key to return to the previous selection.
When in menu mode, the number keys become menu shortcut keys which allow you to quickly jump to certain
menus without scrolling. For example, pressing MENU followed by a <5> jumps directly to the Console Setup
menu. One exception to this is the 0 key, which jumps directly to the call mode without having to press MENU.
The other shortcut keys require the MENU key be pressed first if not already in Menu Mode.
Numeric VS. Alphanumeric Data
There are two different data entry modes available on the TRC. Numeric entry is the default mode when calling a
unit. As numbers are entered, they appear on the bottom-left of the display. Pressing the MENU key while in
numeric entry mode changes the mode to Alphanumeric. In alphanumeric mode, you may type in letters and
numbers as shown in the table below. This allows you to type the name of a user in the database without having
to scroll through the names. Alphanumeric data appears on the bottom line of the display as it is entered. You
may make alphanumeric call entry the default mode by changing the Data Entry Mode setting in the CONSOLE
SETUP menu.
Entering Alphanumeric Data
Before you can add names to the database, you must learn the scheme for entering alphabetic characters using
the numeric keypad. All of the letters of the alphabet appear above the numbers on the keypad. For example, the
letters ‘A’ ‘B’ and ‘C’ appear on the <2> key.
Alphabetic characters are entered by pressing 2 digits. The first digit is the key with the desired letter appearing
on it. The 2nd digit is the position of the letter on that key. For example, the code for the letter ‘C’ is 23 since it is
the 3rd letter on the <2> key. The letter ‘T’ is the 1st letter on the <8> key, so its code is 81.
To enter numeric characters in alphanumeric data entry mode, press the <0> key followed by the desired digit.
Punctuation characters such as comma <,> and <-> do not appear on the keypad. Special codes have been
assigned to allow entry of those characters. Please refer to the following chart.
Note: Alphanumeric mode cannot be used to enter user ID's (ANI's). In alphanumeric mode, numbers are treated
the same as letters
.
A=21 I=43 Q=72 Y=93 7=07 - =15
B=22 J=51 R=73 Z=94 8=08 = =16
C=23 K=52 S=74 1=01 9=09 * =17
D=31 L=53 T=81 2=02 0=00 / =18
E=32 M=61 U=82 3=03 , =11 # =19

G=41 O=63 W=91 5=05 _=13
H=42 P=71 X=92 6=06 +=14
16

Entering Special DTMF Digits: The TRC supports the following special DTMF 'digits' in numeric entry mode: *,
#, A, B, and C (D is not supported). These are entered using 2-key sequences as follows:
