1. GENERAL INFORMATION
1.1 ABOUT THIS MANUAL
This manual describes the installation of the Apollo SL70R transponder. It is intended
for use by persons certified by the Federal Aviation Administration (FAA) to install air-
craft avionics.
Provides GENERAL INFORMATION about the Apollo SL70R unit. TSO
certification information is also included in this section.
Includes INSTALLATION and checkout procedures.
Includes complete POST-INSTALLATION AND CONFIGURATION PROCE-
DURES.
Includes TROUBLESHOOTING information.
Includes LIMITATIONS for the equipment and installation.
Includes PERIODIC MAINTENANCE requirements.
Includes SERIAL SPECIFICATION information.

1.2 APOLLO SL70R DESCRIPTION
The Apollo SL70R is an incomplete system and when connected to an appropriate host,
will function as a TSO-C74c, Class A2, mode A/C transponder. The SL70R, in addition
to providing replies to ATC interrogations, can provide altitude reporting, squawk code
selection, and has built-in self-test and diagnostics.
1.2.1 GENERAL FEATURES
•small footprint
•remotely mounted
•full range input supply voltage
•altitude reporting
•gray code or RS-232 serial data altitude input
•RS-232 altitude data output
•built-in self-test and diagnostics
•host controlled

1.2.2 SYSTEM INTERFACES
1.2.2.1 SERIAL INTERFACE
The SL70R includes an RS-232 serial port which is used to control the transponder from
a host.
When making serial connections to the SL70R, use a shielded two or three conductor ca-
ble. Make the RxD, TxD, and serial ground connections on the 37 pin D-sub connector.
Connect the shield to the rear of the mounting frame on the connector plate.
1.2.3 HOST FAILURE
If the host stops sending altitude data to the SL70R, or upon power up if the SL70R does
not receive data from the host, then within 60 seconds the SL70R will enter Host Failure
Mode. In this mode, the SL70R will revert to altitude reporting (Mode C) using the cur-
rent squawk code. If the power is cycled the squawk code will revert to the default VFR
squawk code.
If the SL70R is configured for gray code altitude input, the transponder will continue to
transmit altitude data. If the SL70R receives altitude data from the host, in the event of
host failure, no altitude data will be transmitted.
If the host resumes normal operation, the SL70R then reports Mode C operation to the
host and altitude reporting resumes if valid serial data is supplied from the host.

2. INSTALLATION PROCEDURES
This section describes the installation of the Apollo SL70R including mounting, wiring,
and connections. A post installation check-out procedure is included in Section 3.
2.1 PRE-INSTALLATION INFORMATION
Always follow good avionics installation practices per FAA Advisory Circulars AC
43.13-1B, 43.13-2A, or current FAA guidance.
Follow the installation procedure in this section as it is presented for a successful installa-
tion. Read the entire section before beginning the procedure. Perform the post installation
check-out before closing the work area in case problems occur.
2.2 INSTALLATION OVERVIEW
A successful installation should start with careful planning including determination of
mounting location for the SL70R, antenna location and mounting, connections to an alti-
tude data source, power, cable routing, and other required modifications.
Once the mounting location has been determined, prepare the mounting frame for instal-
lation. It may be easier to complete the wiring harness and attach the connectors to the
mounting frame prior to installing the mounting frame in the aircraft.
2.3 OTHER REQUIRED MATERIALS
In addition to the materials supplied with the SL70R, the following is required.
•a suitable 2A circuit breaker which the pilot can pull out or disengage must be
used. NOTE: Alternatively, a switch that is within pilot’s reach may be used
in conjunction with a circuit breaker.
•an altitude data source – either gray code or RS232 (host supplied data)
•a standard transponder antenna
2.4 SPECIAL TOOLS REQUIRED
Crimp Tool
A crimp tool meeting MIL specification M22520/1-01 and a positioner/locator are re-
quired to ensure consistent, reliable crimp contact connections for the rear 15 pin connec-
tor. These tools are available from:

2.5 INSTALLATION CONSIDERATIONS
2.5.1 MINIMUM SYSTEM CONFIGURATION
The SL70R requires connections to the following equipment as a minimum:
•power input
•connection to host system
•altitude data – gray code or host supplied serial data
•a standard transponder antenna
2.5.2 MOUNTING CONSIDERATIONS
The SL70R is designed to mount in the avionics bay in the aircraft. The standard package
includes the mounting frame for ease of mounting, connections, and service of the unit.
Allow sufficient clearance to route
cables.
2.5.3 CABLING AND WIRING
Note: The length of cable used for the serial connection between the SL70R and the host should
not exceed 20 feet.
Figure 2-1. Cable Routing
2.5.4 AIR CIRCULATION AND COOLING
For typical installations, the SL70R does not require external cooling.
2.6 EQUIPMENT MOUNTING
Once the cable assemblies have been made, attach the 37-pin D-sub and coaxial cable
connectors to the rear connector mounting plate and the mounting frame. Route the wir-
ing bundle as appropriate. The rear connector plate should be attached to the mounting
frame before installing. The rear connector plate can be used to tie down the cable as-
semblies. Connect the shields on any shielded cables directly to the connector mounting
plate.

Installation Procedures
Apollo SL70R Installation Manual 9
Once the cable assemblies are complete and the connectors are attached to the mounting
frame, install the mounting frame assembly in the aircraft.
The following recommendations are made for fastening the mounting tray to the aircraft.
Note the requirement for some means of locking the fasteners.
Fastener Size: # 8 x 32
Fastener Tensile Strength: 55,000 psi min. (eg MS35206 or AN526)
Washer: # 8 AN960
Locking Feature: Self Locking Nut Plate, Self Locking Nut or Lock Washer (AN365)
2.6.1 UNIT INSTALLATION/REMOVAL
To install the SL70R in the mounting frame slide the unit into the frame and turn the
DZUS fastener clockwise with a DZUS screwdriver. If a DZUS screwdriver is not avail-
able some flat bladed screwdrivers may work. Push the unit fully into the frame, then
turn the DZUS lock.
To remove the SL70R from the mounting frame use a DZUS screwdriver or flat bladed
screwdriver to turn the DZUS fastener counterclockwise. The unit must be pulled out of
the frame by the handle after the DZUS fastener is turned. No special extraction tools are
required.
Figure 2-2. Mounting Tray for SL70R
2.7 ELECTRICAL CONNECTIONS
The SL70R installation kit includes a 37 pin D-sub shell and crimp contacts. 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.

2.8 ANTENNA INSTALLATION AND CONNECTIONS
The antenna should be mounted in a vertical position in an area on the bottom of the air-
craft away from other antennas or landing gear.
The antenna coax cable should be a double shielded low loss cable and must have a cable
loss of < 3 dB at 1090MHz, including connectors. A typical installation should have a
cable loss of 1½ to 2 dB. Several suitable coaxes are RG142B and RG400.
The assembly of the rear panel coax connector included with the installation kit is illus-
trated in the following figure.
