INTRODUCTION

10
Raider Installation and Operation Rev. 1.4.2
The Raider is easy to install. Six connections into an existing DCS (Digital Coded Squelch)
compatible repeater are required. There are repeater interface diagrams in the back of this manual.
Trident also offers factory built interface cables for easy connection to your repeater. Ask your
Trident sales representative for a list of available repeater interface cables.
Unpacking and Mounting
The Raider comes covered in plastic bubble wrap. Inspect the unit for any shipping damage. If any
damage is noticed, please contact Trident Micro Systems immediately.
The Raider should be mounted in a system rack located near the repeater that is to be used, adjusting
the mounting ears to fit (adjustment should not be required for standard EIA racks). Secure the unit
using 4 rack screws.
Power
Clean DC voltage (free of noise and transients) between 11 and 16 volts should be applied to the
Raider. A wall transformer capable of at least 1 amp will work fine. The Raider draws 750mA. If
the DC voltage drops below 10 volts, a low voltage reset circuit will interrupt the flow of current and
the unit will not function. The Raider will begin functioning again when the voltage rises above 10
volts.
A 2amp 3AG fast blow fuse is mounted on fuse clips on the PCB. On the circuit side of the fuse
is a Metal Oxide Varistor (like a zener diode). If a spike over 18 volts enters the unit it is clamped
by the Metal Oxide Varistor at 18 volts until the spike passes or the fuse blows.
Power Indicator
On the front panel of the Raider is a green LED marked POWER. This LED lights up when DC
power is applied to the unit. If the LED does not light up, check to see if the fuse is blown.
Grounding
Grounding is essential for the Raider to operate properly. Make sure the unit is securely mounted
to the rack and that the rack is securely connected to the building ground.
Terminal Emulation
The Raider uses the TELEVIDEO 920 terminal emulation commands. Please configure your
computer terminal program to TVI-920. If your current program does not have this emulation,
Trident recommends the T-Comm Communications program or other compatible program such as
ProComm Plus®. The display may appear distorted and unreadable if the proper emulation mode
is not selected.
INSTALLATION

11
Raider Installation and Operation Rev. 1.4.2
Repeater Connector DB-25 Female Pinout
Receiver Discriminator Input - Pin 1
Connect the repeater receiver discriminator to Pin 1. The Raider will handle up to 16 volts DC on
this input. Signals from 50mV to 1 volt can be accommodated.
It is very important that a connection be made directly to the discriminator IC or detector. Since
the LTR® data is very low frequency, AC coupling may not provide accurate data response. With
most repeaters the nominal voltage on the discriminator is 2 to 5 volts DC. There are repeater
interface diagrams in the back of this manual to aid you in making the direct connection to the
discriminator.
EXT RDD Input - Pin 2
The RDD is jumper controlled. Select internal monitoring to check for a foreign tone on the input
of the repeater (factory shipped) or it can be connected to an external receiver (active low carrier)
which can monitor the output of the repeater (jumper W1). Refer to Appendix E for more
information on connecting an auxiliary receiver to the Raider using External RDD.
TX Audio Output - Pin 3
Connect the repeater TX Audio Input to Pin 3. The transmit audio that goes to the repeater
transmitter is adjustable from 0 to 1 volt peak to peak. This level is sufficient to drive most
transmitters. The output is AC coupled through a 10μcapacitor.

TX Data Output - Pin 5
Connect the repeater TX Data Input to Pin 5. The transmit LTR data is adjustable from 0 to 1 volt
peak to peak. The output may be either AC or DC coupled depending on the transmitter used. DC
coupling is always preferable to AC coupling. With the TX DATA potentiometer fully "ON"
(clockwise) the DC voltage is between 4.2 and 4.8 VDC with up to 1 volt of AC data. Transmitters
designed to be DCS compatible are usually able to drive the modulator directly. After connecting
the Raider to the transmitter, the RF frequency should be checked and adjusted if necessary.
TX PTT Output - Pin 7
If the repeater PTT line is referenced between 10-14 volts, connect the repeater TX PTT Input to
Pin 7. The push-to-talk output can switch 300mA to ground through an FET transistor.
TX PTT Output - Pin 20
If the repeater PTT line is referenced to +5 volts or low voltages (below 10 volts), connect the
repeater TX PTT Input to Pin 20. Pin 20 is protected by an isolation diode.
Ground - Pin 25
Connect the cable ground to Pin 25. Be sure the Raider is secured to a properly grounded rack.
Power - Pin 13
Clean DC voltage (free of noise and transients) between 11 and 16 volts should be applied to Pin
13. The power received from the repeater or wall transformer that is capable of at least 1 amp will
work fine. The Raider draws 750mA or in the Low Power version, less than 300mA. Contact a
Trident Representative for Low Power or solar applications. Ifthe DC voltage drops below 10 volts,
a low voltage reset circuit will interrupt the flow of current and the unit will not function. The Raider
will begin functioning again when the voltage rises above 10 volts. Note: The Raider has been
designed with a SECONDARY lightning protection system. If the site is located in an area where
lightning is a problem, make sure that good PRIMARY lightning protection is installed. Primary
protection of either gas tube or carbon type is recommended.

Raider Installation and Operation Rev. 1.4.2
The COMM PORT (Communications Port) carries RS-232 signals between the Raider and the modem
or computer. The Raider side of this interface is called DTE (Data Terminal Equipment) and connects
directly to any DCE (Data Communication Equipment) device. A modem is a DCE device.
Direct Connection to Computer
Both, the Raider and the PC are DTE devices and will not communicate with each other on a 1 to
1 (straight through) cable. When connecting the Raider directly to a computer for testing or
programming, a null modem cable must be used. The null modem cable swaps Pins 2 & 3 (send
and receive) in its connection from the computer to the Raider. The only connections needed for
most computers are pins 2 RX Data, 3 TX Data and 5 Circuit Ground.
The Raider uses the TELEVIDEO 920 terminal emulation commands. Please configure your
computer terminal program to TVI-920. If your current program does not have this emulation,
Trident recommends the T-Comm Communications program or other compatible program such as
ProComm Plus®. The display may appear distorted if the proper emulation mode is not selected.
About Modems
A "modem" (modulator-demodulator) is a device that converts RS-232 signals to tones that can
be passed over telephone lines. This allows digital communication devices like the Raider to send
information from a remote site to your local phone line. As key strokes are entered on your
keyboard the computer converts them to ASCII data (American Standard Code for Information
Interchange). The ASCII data is then converted to a serial bit stream similar to the data that goes
back and forth between the mobile and trunk system. This serial bit stream is converted to a series
of RS-232 voltage levels that are fed into the modem (+12 volts = 1 and -12 volts = 0). The modem
sends a different tone for each voltage level it receives (2200Hz for 1 and 2100Hz for 0).
When the modem on the "other end" sends a character, two more frequencies are introduced into the
communication stream so that data can be passed in "full duplex" (both directions, simultaneously). The
sending modem converts these tones into RS-232 voltage levels and passes them to your computer. The
computer decodes the ASCII data and displays it on the screen as characters for you to read.
A dial-up phone line at the remote site, a modem connected to the Raider and a modem capable
of auto-dialing connected to your computer are required in order to make remote contact with the
Raider. The modem at the Raider site should be set to "auto answer". When you want to
communicate with the Raider, you must instruct the modem connected to your computer to dial the
phone line connected to the Raider's modem. When the Raider's modem sees the ringing it will
answer the phone and start the data communication between your computer and the Raider.
Certain modems tend to behave unreliably under the adverse conditions sometimes occurring at
a radio site (unreliable AC power, lightning and extreme temperatures). For those reasons, Trident
recommends using the Trident Tuff-Modem at all radio sites. The Tuff-Modem is controlled by
a special microprocessor which is much more reliable under the extremes of site conditions. The
Tuff-Modem requires +12v DC and may be supported by the Raider's power supply.

14
Raider Installation and Operation Rev. 1.4.2
T-NET Connectors and the T-NET Data Bus
The T-NET Connectors are RJ-45 jacks and require 8 Conductor shielded cables running 1 to 1.
They enable the Raider(s) (and Marauders) to be daisy chained together forming a local area
network (T-NET) that allows trunking and other data to pass between channels.
The units at each end of this chain must have jumpers W6, W7, W8, W9, W23 and W24 in place
for proper termination. All other units in the chain should have these jumpers removed. Not having
proper termination can seriously hamper trunk system operations. Jumpers not in use should be set
on one pin as a means of storage, making them readily available at a later time. Refer to page 24
for Raider Jumper Locations and Factory Default Settings.
Note: Any ONE of these units, in the BEFORE or AFTER diagrams, may be set to generate sync.
Each unit has two LEDs on the front panel that show activity on the T-NET Data Bus. These LEDs
are labeled TALK and LISTEN. The TALK and LISTEN LEDs will flash in unison at a steady rate
on the Network Master Raider indicating that that particular unit is generating sync for the data bus
(see Setting SYNC on page 18). The LISTEN LED on all Slave Raiders (units not generating sync)
will flash when they hear the Network Master Talk. Each Slave Raider's TALK LED will flash once
for every 40 LISTEN flashes. Make sure that each Slave controller is talking and listening. It takes
up to 45 minutes for the Network Master to update the Slave controllers with any database
information.
Note: If either TALK or LISTEN LEDs of the Network Master or Slave units are steadily ON, it
is an indication of a jumper, cable or termination problem.
Note: The SYNC LED on the front panel of the Network Master and all Slave units should be
steadily ON. If this LED is blinking, it is an indication of a termination problem or that more than
one unit is generating sync.

Final Connections
When all connections are complete there should be one data bus with properly terminated units,
a modem connected to the Network Master, and each Raider connected to its repeater. The modem
must be connected to the Network Master, the unit that is generating sync. The following diagram
shows how a four channel system should be connected. Your system may have up to 20 channels
in series.
Note: If a Raider must be powered down, it is recommended that the unit be disconnected from
the data bus. If the data bus is not longer than ten feet it is unlikely that leaving an unpowered unit
on the bus would cause any adverse effects. Regardless, it is still not recommended. It is not
unusual to find data buses up to 40' in length. The capacitance found in such data bus lengths with
an unpowered Raider is likely to distort the data, prohibiting the system from operating within
specs.

Repeater Levels - Adjustments
There are six potentiometers to the immediate right of the T-NET connectors for the adjustment
of communication levels.
CW LEVEL
Adjusts the Morse Code ID level. The Morse Code ID is your repeater station identification which
is transmitted every 30 minutes.
RPT AUDIO
Adjusts the Repeater Audio level to the transmitter. This is the master control.
TONE LEVEL
Adjusts the level of the CTCSS tones being sent to the transmitter.
TX DATA
Adjusts the level of the LTR and DCS data being sent to the transmitter.
SQUELCH LEVEL
Adjusts the Internal Squelch threshold. Activity of the internal squelch circuit is displayed by the
CARRIER LED on the front panel.
RX DATA
Adjusts the receiving level of LTR and DCS data being applied to the internal decoder circuitry.

Raider Installation and Operation Rev. 1.4.2
SWITCH 2 Dipswitches
The following sections describe the functions of the Raider's dipswitches.
Data Inversion Switches
The four Data Inversion switches are a subset of the SWITCH 2 switches and are marked with the
word INVERT over them. These switches may be set in different combinations to accommodate
a variety of repeater information formats.
TX DTA
This switch sets TX LTR data polarity. Used if the transmitter inverts data.
RX DTA
This switch sets RX LTR data polarity. Used if the receiver inverts data.
TX DCS
This switch sets TX DCS data polarity. Used if the transmitter inverts data.
RX DCS
This switch sets RX DCS data polarity. Used if the receiver inverts data.
Setting the Repeater Number - 1, 2, 4, 8 and 16
The Raider's home repeater number must be set to a value of 1 through 20. This setting must be
unique and not copied by another channel in the same system. Set the desired repeater number with
the five numbered switches, 1, 2, 4, 8 and 16. The number/name of each switch is the binary value
of the switch and may be set as follows: Turn "on" (DOWN) each switch that is needed to produce
a total value equal to the number of the desired home repeater. See example below.
Note: Switches may be changed hot. You need not reset the power.
Example:
The desired repeater number is 13. Switch 1 = value 1
Turn "on" (DOWN): Switch 4 = value 4
Switch 8 = value 8
repeater #13

18
Raider Installation and Operation Rev. 1.4.2
The AREA Bit
The Area Bit is set to 0 in the factory. When two separate systems have overlapping coverage with
identical frequencies (co-channeled) the Area Bit can make one system distinguishable from the
other. Set one system's Area Bit to 0 and the other system's Area Bit to 1. This prevents mobiles
homed to one system from accessing the neighboring system. Care should be taken to make sure
that all mobiles on each system have been programmed with the corresponding Area Bit.
AREA Switch "off" (UP) = 0
AREA Switch "on" (DOWN) = 1
Setting SYNC
Any ONE of the Raiders in the T-Net Data Bus, regardless of its position (1st, 2nd, 3rd, etc.) may
have sync enabled. The Raider that has sync enabled is automatically designated the "Network
Master". All other Raiders in the chain are referred to as Slave units. Sync must be enabled in one
unit (and only one unit) on the data bus in order for bus communications to function properly. These
operations include validation, logging interconnect airtime and allowing communications with the
Raiders via modem.
SYNC Switch "off" (UP) = use sync from data bus
SYNC Switch "on" (DOWN) = generates sync for T-NET data bus
BAUD Rate
The Raider's RS-232 port can communicate at two common speeds (baud rates) of 1200 or 2400
baud. The Network Master Raider baud rate should be set to the same rate as the modem that is
interfaced to that system. For example, when using the Trident Tuff-Modem (1200 or 2400 baud)
the Raider's BAUD switch should be set in the "on" (DOWN) position for 2400 baud if the Tuff-
Modem is set at 2400 baud.
BAUD Switch "off" (UP) = 1200 baud
BAUD Switch "on" (DOWN) = 2400 baud
LGC SQ
This switch holds the Logic Squelch open when turned "on" (DOWN), enabling carrier test signals
to be repeated.
TX TEST
This switch puts the channel into a busy test mode when turned "on" (DOWN). A 255 LTR Busy
ID is transmitted, which busies out the channel.

19

Test Point - TP1
TP1 RX DATA
This test point is used to read the RX DATA level. Check for 200mV RMS with the repeater
receiving a full quieting signal modulated with a 100Hz tone deviating at 1kHz (800Hz for 12.5kHz
operation).

QUICK START
What Is Quick Start?
Quick Start is the procedure by which the Raider may be quickly set up with basic level adjustments
to get the unit on the air. For those of you who wish to set up the unit with greater precision, please
proceed to the ALIGNMENT PROCEDURE on page 26.
The Raider should be connected to the repeater and disconnected from other logic units. All
dipswitches should be "off" (UP). The repeater should be "on" giving power to the Raider.
Note: All references to dipswitches, test points and potentiometers are made by the component's
name imprinted on the back of the chassis. If the component is not accessible from the back of the
Raider, i.e., the part is inside the chassis, mounted on the PCB, it will be referred to by its PCB
silkscreen name.
Note: You may wish to refer to the Raider Jumper Location and Raider LED, Potentiometer and
Test Point Location charts at the end of the Quick Start section.
