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.
Includes the ENVIRONMENTAL QUALIFICATION FORM.
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.
