Installation
SECTION 2 - INSTALLATION
This section describes the installation of the SL50 and SL60 including mounting, wiring, and
connections. A post installation check-out procedure is included at the end of this section.
PRE-INSTALLATION INFORMATION
Always follow good avionics installation practices per FAA Advisory Circulars (AC) 43.131A, 43.13-2A, AC 20-138, and AC 20-67B, or later FAA approved revisions of these
documents.
Follow the installation procedure in this section as it is presented for a successful installation.
Read the entire section before beginning the procedure. Perform the post installation checkout before closing the work area in case problems occur.
INSTALLATION OVERVIEW
A successful installation should start with careful planning including determination of
mounting location for the SL50/60, antenna mounting, connections to microphones, speakers,
and headphones, cable routing, and other required modifications. Once the mounting location
has been determined, prepare the mounting frame for installation. It may be easier to complete
the wiring harness and attach the connectors to the mounting frame before installing the
mounting frame.
INSTALLATION CONSIDERATIONS
MOUNTING CONSIDERATIONS
The SL50/60 is designed to mount in the avionics stack in the aircraft instrument panel within
easy view and reach of the pilot. The standard package includes a mounting frame for ease of
mounting, connections, and service of the unit. Allow an additional one inch clearance to the
rear of the mounting frame for connectors and cables.
For typical installations, the SL50/60 does not require external cooling. When mounting the
unit, leave a clearance of 1/8 to 1/4 inch between avionics to allow for air circulation.
MINIMUM SYSTEM CONFIGURATION
The minimum system configuration and external connections requirements are described in
the System Configurations section on page 4.
HELICOPTER REQUIREMENTS
The SL60 is qualified for helicopter installation with certain mount tube and SL60
configurations (see Section 4 - Limitations).
EQUIPMENT MOUNTING
Once the cable assemblies have been made, attach the 15 and 37 pin d-sub and coaxial cable
connectors to the rear connector mounting plate and the mounting frame as illustrated in Figure 4
and
Apollo SL50 / SL60 Installation Manual
9
Installation
Figure 5. Route the wiring bundle as appropriate. The rear connector plate should be attached to
the mounting frame before installing the frame in the instrument panel. The rear connector
plate can be used to tie down the cable assemblies. Use the supplied edge guard to protect the
cable from sharp edges. Connect the shield grounds directly to the connector mounting plate.
Once the cable assemblies, the connector mounting plate, and the mounting frame are
assembled, install the mounting frame assembly in the instrument panel. Be sure to use low
profile head screws so the unit will slide in and out freely. Attach the front of the mounting
frame to the instrument panel. Use support brackets to attach the rear of the frame to the
aircraft.
MOUNTING TUBE INSTALLATION
Care must be taken when installing the mounting tube to ensure you can properly insert and
secure the unit. There must be a minimum vertical spacing of 0.040 inches between units to
prevent interference with the cam locking mechanisms. Mounting tubes with clearance
dimples help maintain the proper clearance. The mounting tube must be installed with the
clearance dimples pointing up.
Figure 3 - Full Stack Mounting Tube Spacing
The mounting tube should be flush to the instrument panel and allow sufficient clearance for the
back of the bezel of the unit to mount flush to the mounting tube. Sufficient clearance must exist
in the instrument panel opening to allow ease of insertion and removal of the unit. If the back
10
Apollo SL50 / SL60 Installation Manual
Installation
of the unit bezel does not mount flush to the mounting tube, the connector may not
engage fully.
Secure the mounting tube to the instrument panel structure. Mounting screw heads must not
protrude into the mounting tube. Be sure to use the appropriate screws so the unit will slide in
and out freely. The screws attaching the mounting tube to the instrument panel structure must
not interfere with the insertion of the unit. Failure to prevent interference will result in damage
to the unit or prevent its insertion. Take care that the mounting tube is not distorted when it is
attached to the instrument panel and structural supports. Shims may be necessary to properly
install the mounting tube. If the mounting tube is distorted out of square, the unit may either bind
when being inserted or the cam lock may not engage.
UNIT INSERTION
Position the cam lock as shown below. The front lobe of the cam should be vertical. The cam
lock mechanism should be fully unscrewed (turned counter-clockwise). Slide the unit into the
frame. Turn (clockwise) and carefully hand-tighten (4 in-lb max.) the cam lock mechanism
using only the 3/32" hex driver provided in the installation package. Using a larger tool than
the one provided makes it easy to exceed the allowable torque on the cam lock resulting in
damage to the unit. The unit will be pulled into the frame securing the unit and the connectors
will fully engage. Do NOT overtighten. The back of the bezel must only be flush to the
mounting tube. If the cam lock is hard to turn or the unit does not seat fully, the unit is
probably binding and the mounting tube should be checked.
UNIT REMOVAL
To remove the unit from the mounting frame, turn the screw counter-clockwise with the hex
driver to unscrew the cam lock mechanism. The unit will begin to pull away from the
mounting tube. Turn the screw until slight resistance is felt and then pull the unit from the
frame. Do not exert excessive turning force at the end of the cam lock travel or the unit
may be damaged. With the cam lock fully disengaged, pull the unit straight out holding onto
the sides of the bezel. It is not recommended that you pull the unit out by the rotary knobs. No
special extraction tools are required, if the mounting tube is properly installed.

ELECTRICAL CONNECTIONS
The SL60 installation kit includes 15 and 37 pin dsub shells and crimp contacts, the SL50 has
only the 37 pin shell. The crimp contacts are specified for 20 to 24 awg wire. Make the crimp
connections with a crimp tool as specified in the Special Tools Required section on page 7.
All wires should be 20 to 24 AWG unless otherwise specified. Wiring diagrams are included
in Figure 8 through Figure 11.
POWER
The SL60 requires two power connections, one for the GPS navigation side of the unit, the
other for the comm. Make the power connections to the unit using 20 awg wire.
The GPS navigation power input is internally fused at 3 amps. A separate 2 amp (maximum)
circuit breaker or fuse should be installed for downline overload or short circuit protection.
The comm power input (SL60 only) is internally fused at 7 amps. A separate 5 amp
(maximum) circuit breaker or fuse should be installed for downline overload or short circuit
protection.
Note: Circuits should be protected in accordance with guidelines in AC 43.13-1A,
chapter 11, section 2, paragraph 429.
Warning
When connecting power to the GX unit, reversing the polarity of the connection
will blow the internal fuse. The internal fuse is soldered onto the circuit board
and requires repair at the factory.
AVIONICS OUTPUTS
The SL50/60 includes full avionics outputs for CDI/HSI indicators, autopilot, and
annunciators. These outputs are to be connected as appropriate for the particular installation.
The CDI/HSI outputs may be connected to a dedicated CDI or HSI or to a shared indicator
using an appropriate switching relay. The avionics outputs available are listed in the Avionics
Outputs specification on page 31. Connect the annunciator outputs to lamp indicators as
described in the specifications. The minimum connections required for different installations
are listed in the System Configurations on page 4.
If a switching relay is used to make connections to a shared CDI/HSI, it should be a minimum
of an eight pole relay box with an appropriate selector switch with annunciation. Since the
SL50/60 is not approved for approach operation, the ILS enable signal from a connected ILS
receiver can be connected to automatically switch the indicators back to the nav receiver when
an ILS frequency is selected.
SERIAL INTERFACE
The SL50/60 includes an RS-232 serial port for making optional connections. The serial port
can be used for connecting to such devices as the Apollo 360 map, the Apollo SL40 comm, an
Argus moving map display, or a Stormscope.

When making connections to the SL50/60, use a three conductor shielded cable. Make RxD,
TxD, and signal ground connections to the 37 pin connector. Connect the shield(s) to the rear
of the mounting frame on the connector plate. The shield leads must be < 1.25 inches. See
Figure 5.
Complete serial interface specifications are included in Appendix E.
SIMULATOR SELECT INPUT
The simulator select pin on the 37 pin connector must be connected to ground on pin 25. If
left unconnected, the unit will operate in the built-in simulator mode.
SPEAKER AND HEADPHONE OUTPUTS (SL60 ONLY)
Connect the speaker and headphones to the output pins on the rear connector.
MICROPHONE INPUTS (SL60 ONLY)
Microphone input connections should be made using a twisted pair shielded cable. Attach the
signal ground to the mic ground pin on the rear connector and connect the shield to the rear
connector plate.
TRANSMIT KEY INPUT (SL60 ONLY)
The TxKey input on the rear connector must be pulled low to ground to enable the transmitter.
This input should be connected to a microphone or yoke mounted momentary push button
switch.
INTERCOM SELECTOR SWITCH (SL60 ONLY)
The SL60 includes a voice activated intercom function that can be enabled by an external
control switch. This is an optional connection.
When making connection for the intercom selection, connect the intercom selection input to a
remote mounted normally open switch. A momentary toggle or alternate action switch can be
used. Connect the other terminal of the switch to ground. The intercom function is enabled
when the input is pulled low to ground. The monitor function is inhibited when the intercom
function is selected.
REMOTE FLIP/FLOP INPUT (SL60 ONLY)
The SL60 includes a remote flip/flop input. This is an optional input can be connected to a
remote mounted (such as on the yoke) momentary push button switch which pulls the input
low to ground.
ANTENNA INSTALLATION AND CONNECTIONS
COMM ANTENNA (SL60 ONLY)
The SL60 requires a standard 50W vertically polarized antenna. Follow the antenna
manufacturer’s installation instructions for mounting the antenna.
14
Apollo SL50 / SL60 Installation Manual
Installation
The antenna should be mounted on a metal surface or a ground plane with a minimum area of
18 x 18 inches. The antenna should be mounted a minimum of two feet away from GPS
antennas.
The comm antenna should also be mounted as far apart as practical from the ELT antenna,
preferably one on top and the other on the bottom of the aircraft fuselage. Some ELTs have
exhibited re-radiation problems generating harmonics that may interfere with GPS signals.
This can happen when the comm (SL40 or any other comm) is transmitting on certain
frequencies such as 121.15 or 121.175MHz, which may cause the ELT output circuit to
oscillate from the signal coming in on the ELT antenna coax.
The antenna coax cable should be made of RG-142B or a comparable quality 50W coax.
Assembly instructions for the rear coax connector are included in Figure 6.
GPS ANTENNA
The mounting location and cable connections for the GPS antenna are very important. The
antenna should be mounted no closer than two feet from VHF comm transmitter antennas, six
inches from other antennas emitting less than 25 watts, and two feet from higher power
antennas. Special care should be taken to ensure that the GPS antenna is not mounted in close
proximity to antennas that may emit harmonic interference at the L1 frequency of
1575.42MHz. Refer to the antenna installation manual for installation instructions.
The connectors are included in the installation kit, and are intended for use with RG-142B
size coax cable. If using a different diameter coax, alternative connectors may be required.
Assembly instructions for the connectors are included in Figure 6 and Figure 7. RG-142B
cable can be used as long as the length is less than 20 feet. For longer lengths, use a low loss
50W coax.
Suggestion: Temporarily locate the GPS antenna with coax connected to the SL50/60 and
check the GPS performance as described in the GPS Operation and Position test in the Post
Installation Checkout on page 24. Once a suitable location has been verified, then
permanently mount the antenna.
Note: If using a GPS antenna that was already on the aircraft, or if mounting the antenna
closer than two feet from a comm antenna, conduct the GPS Operation and Position test in
the Post Installation Checkout on page 24. If the SL50/60 passes the test, then moving the
antenna is not necessary.
Once the antenna mounting position has been prepared. route the coax cable from the antenna
to the SL50/60. Proper selection of coax cable and assembly of connectors is critical to GPS
signal performance. The cable loss from the antenna to the SL50/60 should be limited to a
maximum of 4db. Minimize the coax length for optimum performance and DO NOT coil
excess cable. Leave only enough for service loops. The coaxial connectors and adapters, such
as TNC to BNC, add additional loss to the cable and should be considered when computing
the maximum 4db loss. A typical loss of 0.2db can be used for each connection. The typical
cable loss for 20ft of RG-142B coax with a connector on each end is 4db.
During the post-installation checkout, susceptibility to harmonics of VHF comm transmitters
will be evaluated. If problems arise, then better isolation, or distance, may be required
Apollo SL50 / SL60 Installation Manual

Installation
between the GPS and comm antennas, or a notch filter may be installed in series with the
antenna coax of the VHF comm transceiver to reduce or eliminate the harmonic interference.
A notch filter for this use (part #162-1059) is available from II Morrow.
Note: The SL60 performance has been verified in typical installations and has not shown to
have problems with the built-in comm interfering with the GPS when installed according to
the recommended installation guidelines.
If a VHF comm transmitter causes problems with the GPS on the selected frequencies as
listed in the post-installation checkout, the problem may be due to the ELT. This can be
verified by disconnecting the ELT antenna coax at the ELT unit. If the ELT is found to cause
the problem, then contact the ELT manufacturer or replace the ELT.

e) Repeat for each comm transmitter.
f) If the SL50/60 is susceptible to VHF comm transmitter interference, then better
isolation, or distance, may be required between the GPS and VHF antennas. With
some comm transmitters, a notch filter may be required in series with the VHF
comm antenna coax at the rear of the comm unit.
Note: Older VHF comm transmitters may emit higher levels of harmonic interference
causing greater problems and may be more difficult to deal with.
Interface Checks
The interfaces to other equipment, such as the SL40 or a moving map display, should be
checked. Refer to the SL50/60 user’s manual for this part of the checkout. Make sure the other
equipment is connected and switched on.
To check the serial data output connections, verify the data from the SL50/60 can be displayed
on the other units, such as a moving map display or the SL40.
VHF COMM CHECKOUT (SL60)
Receiver / Transmitter Operation
Tune the unit to a local frequency and verify the receiver output produces a clear and
understandable audio output. Verify the transmitter functions properly by contacting another
station and getting a report of reliable communications. Check the remote flip/flop.
Antenna Check
The antenna VSWR can be checked using an inline watt meter in the antenna coax using
frequencies near both ends of the band. The VSWR should be < 2:1, and is not to exceed 3:1.
A VSWR of 2:1 will cause a drop in output power of approximately 12%, and 3:1 causes
approximately a 26% drop.
Sidetone Level Adjustment
The sidetone volume was preset at the factory to a typical audio level. The level can be
adjusted using one of the built-in system functions. To adjust the sidetone level:
1. Press SYS, rotate the LARGE knob to the “COM RADIO INFO:” page, and press ENT.
2. Rotate the LARGE knob to the “SIDETONE LEVEL:” page.
3. Rotate the SMALL knob to adjust the sidetone level. The sidetone level is displayed in a
range of 000 to 255, with 255 the highest level. The sidetone level can be adjusted during
transmit.
Comm Flight Test Check
A flight test is recommended as a final installation verification. The performance may be
verified by contacting a ground station at a range of at least 50nm while maintaining an
appropriate altitude and over all normal flight attitudes. Performance should be checked using
low, high, and mid band frequencies.
FINAL SYSTEM CHECK
The SL50/60 GPS navigation functions should be complete at this time. The final check
includes checking database, entering a direct to waypoint, and checking the navigation

functions. Start with the unit turned on and operating in the normal mode. Refer to the user’s
manual for operating instructions.
1. Verify a valid position is displayed.
2. Check the database to ensure it is for the right coverage area and is not expired. To
check the database:
a) Press SYS, rotate the LARGE knob to the “SYSTEM INFO” page, and press ENT.
b) Rotate the SMALL knob to display the database information. The database name,
expiration date, and version will be displayed.
3. Enter a direct to waypoint. Press the DIRECT-TO button, use the LARGE and SMALL knobs
to select a nearby waypoint, then press ENT. Or use the nearest search function to select
a waypoint.
4. Verify the bearing and distance to the selected waypoint.

Periodic Maintenance
APPENDIX B - PERIODIC MAINTENANCE
The SL50/60 unit is designed to not require any regular general maintenance except as
included in this section.
LITHIUM BATTERY REPLACEMENT
The internal keep alive battery will require replacement after 4 to 6 years. Regular planned
replacement is not necessary. The SL50/60 will display a “low battery” message when
replacement is required. Once the low battery message is displayed, the battery should be
replaced within 1 to 2 months. If the battery is not replaced, the internal ram memory and the
system clock information will be lost.
To replace the battery, remove the SL50/60 from the aircraft, remove the top cover, and
replace the battery. Make sure to insert the battery in the correct polarity. Replace the top
cover, re-install the unit in the aircraft, and verify unit operation.
Battery replacement should be done only by the II Morrow factory or by a trained technician.
Note: The battery is to be replaced only with II Morrow part #148-1702, or a
II Morrow approved equivalent.
Caution
The battery may explode if mistreated. Risk of fire, explosion, and burns. Do
not recharge, disassemble, heat above 100°C, or incinerate.
Dispose of batteries promptly. Keep away from children.
Be sure the battery is inserted in the right direction.
EQUIPMENT CALIBRATION
The SL50/60 design requires very few adjustments or calibration to be made. In fact, there are
no internal manual adjustments.
REFERENCE OSCILLATOR
The reference oscillator frequency should be checked approximately every 3 to 5 years to
ensure the units transmit frequency is within allowable tolerance.
The oscillator frequency can be checked by connecting the transmitter output through an
appropriate load to a calibrated frequency counter. The transmit frequency should be within
15ppm of the selected channel frequency. Contact the II Morrow factory for instructions on
adjusting the frequency if required.
CLEANING THE FRONT PANEL
The front bezel, keypad, and display can be cleaned with a soft cotton cloth dampened with
clean water. DO NOT use any chemical cleaning agents. Care should be taken to avoid
scratching the surface of the display.

The comm data is output using the following format.
$PMRRC<msg_id><msg_data><chksum><cr>
The checksum is computed by an 8 bit addition of the msg_id and msg_data characters,
ignoring carry if any. The resulting 8 bit checksum is converted to two ascii characters by
taking the upper and lower nibbles, adding 30h to each, and placing the most significant

The above example message outputs a ground frequency type, 121.900 MHz.
Remote VOR List
The following two commands work together in allowing remotely connected devices to
provide a list of VOR frequencies to the SL30. The remote device will send a sequence of
Remote VOR Input commands (message identifier 20). When all of the VOR Input
commands have been sent, the remote device should send a Remote VOR List Trailer
command (message identifier 21) to terminate the list. The transmitted list will not be
considered complete by the SL30 until it receives the trailer message. The unit will maintain
a single remote VOR list, so each list received will replace any previous list. There may be up
to twenty entries in the remote VOR list. Any entries past twenty will be ignored.
Remote VOR Input
This input is used to input VOR frequency data used for the remote recall function.
The data consists of five characters for the VOR station identifier followed by two characters
defining the VOR frequency.

characters, then the trailing characters will be filled with spaces. Station
Identifiers are restricted to using ASCII characters 0-9 and A-Z.
mk ..................Frequency: m = MHz, where m = desired MHz frequency – 30h, with the
desired frequency ranging from 108 to 117, or 3Ch to 45h; k = kHz, where
k = (desired kHz offset / 25 kHz) + 30h, with desired frequency range of
000 to 975 kHz in 50 kHz steps, or the even numbers from 30h to 56h.
Note that the field will be checked to ensure that it is in range and a valid
VOR frequency. Frequencies used for localizers, which are in the range of
108.10 to 111.95 MHz, will not be accepted in this message type.
Example message:
$PMRRV20UBG<Sp>E@<chksm><CR><LF>
VOR station identifier is “UBG ”, VOR frequency is 117.400 MHz.
Remote VOR List Trailer
This input command marks the end of a VOR list sent by a remote device.
Message format:
“V” Message Class. This is a VHF NAV message.
“21”
Message Identifier
Example message:
$PMRRV21<chksm><CR><LF>
Indicates the start of a remote VOR list.
REMOTE LOCALIZER LIST
The following two commands work together in allowing remotely connected devices to
provide a list of localizer frequencies associated with an airport to the SL30. The remote
device should first send the Remote Localizer List Header command (message identifier 22),
followed by a sequence of Remote Localizer Input commands (message identifier 23). The
SL30 maintains a single remote localizer list, so each new list received will replace any
previous list. Subsequent receptions of localizer lists for the same airport are ignored. There
may be up to twenty entries in the remote Localizer list. Any entries past twenty will be
ignored.
Remote Localizer List Header
This input command marks the beginning of a Localizer list sent by a remote device. It
specifies the five character airport identifier associated with the localizer frequencies in the
list.
Message format:
“V”.................Message Class. This is a VHF NAV message.

aaaa................ Airport identifier. Note that if the airport identifier is less than four
characters, then the trailing characters will be filled with spaces. Airport
Identifiers are restricted to using ASCII characters 0-9 and A-Z.
Example message:
$PMRRV22SLE<Sp><chksum><CR><LF>
Indicates the start of a remote localizer list associated with the airport “SLE ”.
Remote Localizer Input
This input is used to input Localizer frequency data used for the remote recall function.
The data consists of three characters to identify the runway associated with the localizer,
followed by two characters defining the frequency.
Message format:
“V” ................ Message Class. This is a VHF NAV message.
“23” ............... Message Identifier.
iiii .................. Station or Runway identifier. This field will provide an identifier for the
localizer which can be either the actual station identifier or a string
indicating the runway associated with the localizer. The station identifier
can be up to four characters long. A runway identifier will typically be
two numbers that indicate the runway direction followed by the character
“R”, “C”, or “L” to differentiate between parallel runways (right, center,
and left). Note that if either type of identifier is less then four characters,
then the trailing characters will be filled in with spaces. Identifiers are
restricted to using ASCII characters 0-9 and A-Z.
mk.................. Frequency: m = MHz, where m = MHz frequency – 30h, with the desired
frequency ranging from 108 to 111 MHz, or 3Ch to 3Fh; k = (desired kHz
offset / 25 kHz) + 30h, where the desired frequency ranges from 000 to
950 kHz, or the even numbers from 30h to 56h. Note that the field will be
checked to ensure that it is in range and a valid localizer frequency.
Frequencies used for VORs, which can also be found in the range of
108.10 to 111.95 MHz, will not be accepted in this message type.
Example message:
$PMRRV2331<Sp><Sp>><<chksm><CR><LF>
Identifier is “31 ”, indicating a runway, and the localizer frequency is 110.300 MHz.
