navigation. This section defines the minimum requirements.
VFR GPS NAVIGATION INSTALLATION
When installed for VFR operation, the SL50/60 requires only the following minimal
connections.
·an A-33 GPS antenna
·power input
The SL50/60 can also be connected to other external devices such as:
·an external non-numeric indicator, such as a CDI or HSI
·external lamp annunciators including “MSG” and “PTK”
·an “OBS/HLD” external annunciator (with switch)
·an autopilot
·a moving map display connected to an RS-232 serial output
When the SL50/60 is installed for VFR, a placard stating “GPS Limited to VFR Use Only” or
an FAA approved equivalent statement must be placed next to the primary indicator
IFR GPS NAVIGATION INSTALLATION
When installed for IFR operation, the SL50/60 requires connections to several external
indicators. The minimum connections for IFR operation is as follows.
·an A-33 GPS antenna
·power input
·an external non-numeric indicator, such as a CDI or HSI
·external lamp annunciators including “MSG” and “PTK”
The following additional connections are recommended, but not required.
·an “OBS/HLD” external annunciator (with switch)
The SL50/60 can also be connected to other external devices such as:
·an autopilot
·a moving map display connected to an RS-232 serial output

Introduction
Apollo SL50 / SL60 Installation Manual 5
COMM TRANSCEIVER - SL60
For standalone installations, the comm requires connections to:
·a standard comm antenna
·a microphone (or microphones)
·a speaker or headphone
·power input
These items may be installed dedicated to the SL60 comm, or by connection to an audio
panel.
DATABASE UPDATES
The SL50/60 includes a built-in Flybrary database stored in flash memory. The database can
be updated through the RS-232 connection on the rear of the unit using a PC. The Waypoint
Manager program (available from II Morrow) is required.
The database can be updated by removing the SL50/60 from the aircraft and connecting it to a
PC and providing a 10 to 40 volt DC power source. A cable assembly (see page 45) is
available from II Morrow for this purpose.
To update the database. connect the SL50/60 to power and the PC. On the SL50/60, press SYS,
rotate the LARGE knob to select the “DATABASE UPDATE:” page, then press ENT. Follow the
Waypoint Manager instructions for downloading the new database. The SL50/60 will display
the programming status, when it is complete, and if an error occurs.
Contact the II Morrow factory for information on databases available for the SL50/60.

Installation
Apollo SL50 / SL60 Installation Manual 9
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) 43.13-
1A, 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 check-
out 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

Installation
10 Apollo SL50 / SL60 Installation Manual
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

Installation
Apollo SL50 / SL60 Installation Manual 11
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.
