OPERATING A TW-60
INTRODUCTION
Thank you for choosing this Clear-Com product.
“Radio interoperability” is the ability of public safety providers – law
enforcement, firefighters, EMS, emergency management, public utilities,
transportation and other personnel – to exchange voice communications on
demand, in real time. It is the term that describes how radio communications
systems should operate between and among agencies and jurisdictions that
respond to common emergencies. Communication should be achieved regardless
of the brands, model numbers, or frequency ranges of the radio equipment used.
The TW-60, in conjunction with an associated Clear-Com matrix
communications system, can be installed with an existing Land Mobile Radio
communications system to provide interoperability.
Please read this manual completely to better understand the functions of the
TW-60. This manual is to be used in conjunction with the manuals supplied for
the associated Clear-Com matrix communications system. For questions not
addressed in this manual, contact your dealer, distributor, or Clear-Com directly.

• Receive Level Adjust: Used to adjust the receive level of the base station
two-way radio when there is no external volume control on the base station
radio.
Note: The receive level is set at the factory and should be adjusted only if the
remote radio does not have its own volume adjustment. The default is 12
o'clock, (1/2 rotation).
• Transmit Level Adjust: Use the TRANSMIT LEVEL ADJUST volume control
to set the level of the intercom's audio as heard at the remote station radio. The
factory default is 12 o'clock, (1/2 rotation).
• Transmit Delay: This rotary switch enables and adjusts the key up delay
available for each two-way radio. The available settings are shown in Table 1.
• Audio LED: This green LED illuminates when the system has sensed audio
from another channel and is supplying audio to this channel to be retransmitted.
• Key LED: This red LED illuminates when this channel is keying its associated
transmitter.
• Level LED: This bi-color red/green LED indicates audio levels received into
the system. Use this indicator to adjust the volume control on the two way radio
to match the system levels. The LED turns red when the signal is too high. Note
that proper audio levels cause the LED to light green when speaking, but flash
red about 10 percent of the time.

Refer to Table 3.
TRANSMIT DELAY
For each of the four interface channels, a knob is provided on the front panel to
set the amount of time that audio will be delayed before it is transmitted. The
Transmit Delay is adjustable as follows:
POSITION ACTION
0 Delay is off, speech transmits immediatley
0.25 Delay is 0.25 seconds
0.5 Delay is 0.5 seconds
0.75 Delay is 0.75 seconds
1Delay is 1 second
1.5 Delay is 1.5 seconds
2Delay is 2 seconds
2.5 Delay is 2.5 seconds
3Delay is 3 seconds
4Delay is 4 seconds
5Delay is 5 seconds
Auto Delay is adjusted automatically
Table 1: Transmit Delay Switch Positions
In many trunking radio systems, the delay from keying a transmitter to having a
voice channel ready for use may be variable. The Automatic Transmit Delay
setting is useful in this situation to provide the minimum delay necessary for a
complete voice transmission. When set to automatically delay the transmitted
voice, the TW-60 listens for the tones the two way radio is producing and delays
the transmission of the voice until the tones stop.

You can wire the TW-60 to
a wide variety of two-way
radio audio and control
connections.
INSTALLING A TW-60
There are eight basic steps to installing the TW-60 Public Safety Radio Interface:
1. Wire cables for connecting the TW-60 unit to radios.
2. Install the TW-60 unit in an equipment rack.
3. Connect the the TW-60 unit to power,
4. Connect the TW-60 unit to radios.
5. Connect the TW-60 unit to a Clear-Com matrix,
6. Connect the TW-60 unit to general-purpose outputs (GPIs).
7. Adjust tranmsit levels.
8. Verify operation of the system.
CONNECTION TO RADIOS
In order to accommodate the widest variety of 2-way radios, each interface
channel of the TW 60 has a 9-pin DB-9F connector which can be wired to a
wide variety of two-way radio audio and control connections. Wiring diagrams
for many two-way radios are supplied as examples of cable wiring. (See
addendum sheet) This will allow you to make a cable that will operate with your
particular radio(s). Each connector socket is labeled on the TW-60's back panel
as Two-Way Radio.

Table 2: Two-Way Radio DB-9F Connections
The combination of setup switches, connector wiring and front panel "Transmit"
and "Receive" level controls assures correct level matching to virtually any radio.
A relay provides the required "Push-to-Talk" transmitter "keying" of the radio.
This relay is activated when the Clear-Com matrix communications system
TW-60 PUBLIC SAFETY RADIO INTERFACE
2-1
commands it. The relay contacts, in conjunction with the cable wiring chosen,
allow for correct transmitter keying to virtually any type of radio.
In addition to the following table, refer to the Block Diagram section of this
manual for a simplified diagram showing the Two-Way Radio connections to the
DB-9F connectors.
WIRING THE TWO-WAY RADIO CABLE
To connect the base-station radio to the TW-60, you must build your own
custom connector cable. This involves several steps:
1. Obtain or make a cable using the kind of plug that fits your radio. Use single
conductor shielded wire for each cable. Miniature type stereo cable is a good
choice. Solder these cables to the DB-9 connector as shown in Example 1.
This cable length should be kept less than 5 feet. A good source of molded
connectors for your radio would be an external microphone or earphone
which can be purchased from your radio supplier. You will need to cut off the
microphone or earphone as it will not be needed.
2. The next step will be to set the type and level of microphone. The TW-60 has
three Setup Switches for each interface channel that can be set for specific
types of microphones. The three illustrations that follow show how the
TW-60 switches and the male DB-9 connector on the channel cable are
configured for most radios. The section that follows, "Setup Switches," gives
instructions for setting the TW-60's Setup Switches.
3. The most difficult setting is often getting your particular radio to key properly.
Every radio has a different method of externally keying its transmitter. To
determine how to set the jumpers and wire the connector, you need to know
what type of external microphone is used in your radio, or you need to
experiment. Below are three examples of how to key the transmitter. If you are
unsure of which wiring to use, try all three, one at a time. Pins 2, 3, 4 and 7
are the relay contacts in the TW-60. If your radio model is not listed in the
addendum sheet and you have tried all three examples, but you still can't
make the two-way radio work properly, call customer service and we will help
you get the system working.
SETUP SWITCHES
Table 3 shows the location of the Setup Switches on the back panel. There is one
set of three for each of the four channels. The switches are set to ON when they
are in the down position and are set to OFF when they are in the up position.
Output Level Switches: Set switches 2 or 3 to ON to lower the signal level to the
two way radio's microphone input. The switches change the levels, as shown in
Table 3. In general, set switch 3 to ON for most low-level mics (for example,
electrets): set both switches 2 and 3 ON to further reduce the input level for
dynamic type mics.
TW-60 PUBLIC SAFETY RADIO INTERFACE
2-2
Transmit Key Switch: For some two-way radios, a dedicated power path may be
needed to activate the Transmit function. If so, set switch 1 to ON, as shown in
Table 3.
SWITCH 1 SWITCH 2 SWITCH 3 FUNCTION
Off Off Mic input range is + 11 dBv to - 20 dBv
Off On Mic input range is - 26 dBv to - 48 dBv
On On Mic input range is - 30 dBv to - 57 dBv
On Provides a dedicated power path to key Transmit
Off Removes power path
Table 3: Setup Switch Positions
RACK MOUNTING
The unit requires 1.75 inches (44 mm) (1RU) of rack space. It requires no
additional free rack space above or below it for ventilation. The station is 5.25
inches (133 mm) in depth and requires at least 2 1/2 inches clearance in the rear
for connectors and cables. The single-piece front panel has integral "rack ears".
This adds stability and strength. Take care not to over tighten the rack mounting
screws as this can mar the front panel.
CONNECTING THE TW-60
Make the necessary back panel connections to the TW-60:
1. Plug the power cord into the IEC receptacle of the TW-60 and connect the
power cord to an unswitched AC outlet.
2. Connect the two-way radio cables from the DB-9F connectors on the TW-60
to each two-way radio.
3. Using 730239 cables, connect the Channels 1 through 4 Matrix Audio
Connectors of the TW-60 to the appropriate connectors on the Clear-Com
matrix. As can be seen in Table 4, four of these cables are needed for each
TW-60 unit.
4. Using a 730240 or a 730241 cable, connect the GPI cable from the DB-9M
connector on the TW-60 to the DB-25F GPI connector on the Clear-Com
matrix. Use the cable shown in Table 4 for each TW-60 unit. Each cable
serves two units.

VERIFYING OPERATION OF THE TW-60 SYSTEM
After the interconnections have been made, and programmed with the
Clear-Com matrix communications system as described in its manuals, it is now
time to check that everything is working properly:
1. Using the documentation supplied with the Clear-Com matrix
communications system as a guide, place all of the radio interfaces into one
group.
2. Turn on the base station two-way radio and the remote radio. Make sure you
have fresh or fully charged batteries. With the external jacks on the base
station removed, make sure the radios can communicate with each other.
3. Set all the Receive Level and Transmit Level controls on the TW-60 to their
mid position. Set the Transmit Delay Switch for each channel to 0.
4. Turn on the TW-60 using the power switch on the back panel. The green
power indicator on the front panel should light and the red fault indicator
should be off.
5. Set the base station two-way radio volume control to approximately zero
volume. Key the remote radio associated with the base station radio.
Gradually increase the volume control on the base station two-way radio until
the green Audio light on the channel associated with that radio lights. The
volume control should be set to the minimum level that will light the green
Audio light with the sound of the radio unsquelching.
6. Repeat the previous step for each radio on the other channels.
7. When the volume controls have been correctly adjusted, keying any remote
radio should result in the Audio LED lighting on the associated TW-60
channel and also in the Transmit Key LEDs lighting on the other TW-60
TW-60 PUBLIC SAFETY RADIO INTERFACE
2-5
channels. The transmit indicator on the base station radios (if any) on these
channels should also illuminate.
8. Now verify that when any remote radio is keyed, the others can all hear the
transmission. To avoid feedback, it is helpful to have the remote radios some
distance away or in another room. The Transmit Level controls on the TW 40
adjust the volume to the remote radios. If the audio heard on any remote radio
is too loud or too weak, adjust the Transmit Level control for that radio on its
associated TW-60 channel. While speaking on the remote radio, the Transmit
Level LED on the other channels should be flashing green with some
occasional red. You may need to adjust the Setup Switches on the
transmitting channel to set the audio signal to the level needed by the mic
circuit of that radio. Adjust switches 2 and 3 as described in Table 3.
9. You should now be able to communicate from any remote radio to the other
remote radios. Pressing the talk key on each remote transmitter should key any
other base station transmitter channels in the same group. Note whether the
key up time of any given channel prevents the first words from being received.
If the first words are missed on any channel(s), turn the Transmit Delay
Switch for that channel to add more audio delay. Adjust for the minimum
delay that consistently transmits the first words promptly and correctly. For
trunking radio systems which have an inconsistent delay that varies depending
upon conditions, set the Transmit Delay Switch to Auto.
10.If there are other TW-60 units in the system, program each one using the
above steps. When all have been programmed, verify that any radio channel
on any TW-60 can be retransmitted onto all of the other channels on all of
the TW-60 units.
