Introduction
Before you begin, you will need to have a copy of KPG-49D and programming cable
available to program the mobile radio. Also, you will need a copy of the Pyramid 2012
programming software and FY-1 programming cable to program the 2012.
** In older versions of Pyramid Communications 2016 and 2012 units, you will need to
replace the PTT transistor with a standard NPN (2N4401) transistor. Without this
modification, you will experience no transmit audio out of the Kenwood 80 Series
version-2 radios. (2012 PTT transistor Q2, 2016 PTT transistor Q3)
Programming the Pyramid 2012/Merlin
The mobile data terminal needs to be programmed to accommodate the polarities of
signal that the Kenwood mobile will provide it.
If you have not already done so, install the programming software on to your PC by
following the instructions in the 2012/Merlin service manual.
Start running the Pyramid 2012/Merlin programming software on your PC. From the
Data pull down menu, under the System Data screen, program the unit as shown the
figure below.

Programming the Kenwood TK-x80 Series Mobile
To begin programming your TK-x80 series mobile for use with the Pyramid
Communications Model 2012/Merlin mobile data system, you will need to first create a
new profile using your KPG-49D programming software.
Radio Format
When programming the radio select trunking or conventional, make sure that you set the
Radio Format correctly upon creation of your new profile. See figure below.
+--------------------------+
¦ Radio Format ¦

¦ 2. Trunking ¦
+--------------------------+
Programming Optional Features
From the Edit pull down menu, select Optional Features. Depending on your
application, most of the parameters in the Optional Feature menu will be left at default.
Although this may be the case, in order to enable a data terminal interface you must
program Com 2 (Internal Port) as AUX Hook/PTT. This enables the external PTT from
the data terminal. See the figure below for more information.

+---------------------------------------- +
Programming the Talk Group information for a 2012/Merlin MDT
When using the TK-x80 series radio in mobile operation along with a Pyramid
2012/Merlin, it is desirable to use a separate talk group for data aside from voice
communication. In order to do this, it is necessary to add a talk group for data to the
system. The figure below depicts a typical talk group configuration.

Programming the Pyramid 2016
Programming of the Pyramid 2016 base modem is done through the console interface.
Typically, the parameters are set in the Pyramid Console software, and then automatically
sent to the 2016. If you are using Manning NavComp Inc’s RasTrac MX software for
you console interface, all configuration is done within the RasTrac I/O processor that
runs on your PC simultaneously with the RasTrac mapping software. Consult your
RasTrac manual for more information.
The figure below shows how a typical Pyramid Console software would be set up when
connected to a 2016 and TK-x80 series radio. To access the Modem Parameters menu,
select Configure from the pull down menu.
+------- Modem Parameters -----+

Understanding Base Channel Change
In order to understand the operation of data channel change you have to realize that the
mobile units are using a dedicated PassPort/LTR ID code for data and a separate
PassPort/LTR ID code(s) for voice communication. When the MDT sends a message, the
mobile radio is switched to the defined data PassPort/LTR ID; after the transmission is
complete, the radio reverts back to the voice ID code. The 2016 base unit receives and
responds on the data PassPort/LTR ID code.
A problem arises when the dispatcher needs to send an outbound message (e.g. GPS Poll,
Text Message, Horn Honk, etc.). At most times, the mobile units are idle and therefore
on the voice PassPort/LTR ID code. When a message from the base is sent, it is sent on
the data PassPort/LTR ID code, thus the targeted mobile unit does not receive the
command from the dispatcher because it is listening on a different PassPort/LTR ID code.
To overcome this obstacle, the 2016 can be configured to change to the voice
PassPort/LTR ID code when sending outbound, base originated messages. As with all
base modem installations, a dedicated radio is required for the 2016 base modem.
Configuring your 2016 for Voice Channel Change
There is a simple wiring harness change is needed to enable the 2016 to activate the
channel change line out of the 2016 Base Modem. From the 2016 wiring harness,
connect the Teal wire ground. This activates the Grey wire as the Voice Channel Select
line.
Crimp a Molex pin onto the Grey wire from the Pyramid Communications Model 2016
wiring harness and connect to the Kenwood KCT-19 Pin 15. See figure below of Molex
pin layout.

Programming the Talk Group information for a 2016 Base Modem
The following is an example of how to setup your Kenwood 80 series radio for voice
channel change on base initiated messages. Group 1 is the data channel. This is the
channel that all messages from mobile units will be received on. Group 2 is the channel
that all of the voice traffic will be occurring.
When the 2016 base modem keys up the base radio to send a outbound message, the
radio will be switched to Group 2;after the transmission it will immediately revert back
to Group 1 to listen for messages from any MDT unit.
Follow the screen shots below to program the Kenwood radio for group change.

Supporting the Kenwood KDS-100 /w Merlin AVL
Modifications To Kenwood TK-x80 Mobile Radio
When you are installing both a KDS-200 Data Head and a Merlin 2017 AVL unit onto
the same radio, some modifications have to be made to get all proper signals to the KCT-
19 connector. When you are connecting a KDS-100 without a Merlin AVL unit to a
radio, you normally use a KCT-34 option connector. In this case you will be using a
KCT-19 option connector kit. You will have to perform the following modifications to
the KCT-19/Radio to connect all required signals to the KCT-19 output:
1) Remove the Red wire from pin 2 of CN1 and solder this wire to pin 3 of CN2 in
the TK-x80 radio.
2) Remove the Orange wire from pin 3 of CN1 and solder this wire to pin 2 of CN2
in the TK-x80 radio.
3) Be sure to install the “E” lead of the KCT-19 into CN-4 of the TK-x80 radio.
Once the above modifications are complete, you will have all necessary signals available
for both the KDS-100 and the Merlin AVL at the KCT-19 15 pin connector. From this
point you will need to install the 7525-10-1044 “Y” cable to split the necessary signals
between the KDS-100 and the Merlin AVL. Plug the 7525-10-1044 “Y” cable into the
KCT-19 from the radio.
KDS-100 Modifications
The KDS-100 connects to the KDS-100 side of this 7525-10-1044 “Y” cable. Your
KDS-100 will need to be programmed for “PC” mode.
Merlin AVL Modifications
The Merlin connects to the 2017 Merlin side of the 7525-10-1044 “Y” cable. No changes
are made to the interface of the Merlin AVL to the KCT-19 vs. the interface of a Merlin
AVL to a 7525-10-1044 “Y” cable.
1) Rather then inserting the Grey wire from the Merlin AVL into pin 15 of the
Kenwood Connector, Insert the Grey wire from the Merlin AVL into pin 1 of the
Kenwood Connector.

15
Modifications To Kenwood TK-x80 Base Radio
When you are installing both a 2016 Base Modem and the interface to the PC for
FleetSync Data, some modifications have to be made to get all proper signals to the KCT-
19 connector. You will have to perform the following modification to the KCT-19/Radio
to connect all required signals to the KCT-19 output:
1) Remove the Red wire from pin 2 of CN1 and solder this wire to pin 3 of CN2 in
the TK-x80 radio.
2) Be sure to install the “E” lead of the KCT-19 into CN-4 of the TK-x80 radio.
Once the above modifications are complete, you will have all necessary signals available
for both the 2016 Base Modem.
Note: With this modification, instead of inserting the Grey wire from the Merlin AVL into
pin 15 of the Kenwood Connector, Insert the Grey wire from the Merlin AVL into pin 1 of
the Kenwood Connector.
From this point you will be feeding your PC with two separate serial data signals, one
from the 2016 base modem and one from the PC output of the TK-x80 radio, providing
the FleetSync data to the PC.
