Introduction SECTION 1 - INTRODUCTION ABOUT THIS MANUAL This manual describes the installation of the Apollo SL50 GPS and SL60 GPS/Comm units. It is intended for use by persons certified by the Federal Aviation Administration (FAA) to install aircraft navigation devices. It includes installation and checkout procedures for the SL50 and SL60 units to standards described in FAA advisory circulars AC 20-138 (for GPS) and AC 20-67B (for comm).
Introduction Figure 1 SL50 Front Panel Figure 2 SL60 Front Panel 2 Apollo SL50 / SL60 Installation Manual
Introduction FEATURES The GPS navigation features for the SL50 GPS and SL60 GPS/Comm include: · 32 character high-intensity alphanumeric LED display · Automatic display intensity · Back-lit buttons · Simple “Direct-To” navigation · Built-in data base updatable through a serial port · Nearest waypoint search (includes airports, VORs, NDBs, intersections, and user waypoints) · Remote waypoint search · Navigation displays - Lat/Lon to 0.
Introduction · · · · · · · Frequency monitor function Weather channels (only in Americas database) Built-in intercom function Frequency memory and recall functions - from navigation data base - eight last used - eight user stored Two microphone inputs 12 watt audio amplifier Remote flip/flop input SYSTEM CONFIGURATIONS The SL50 and SL60 can be installed in several configurations based upon individual requirements. This includes with or without the comm transceiver, and VFR or IFR GPS navigation.
Introduction 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.
Introduction UNPACKING THE EQUIPMENT Carefully unpack the equipment. Visually inspect the package contents for any evidence of shipping damage. Retain all shipping containers and packaging material in case reshipment is necessary. PACKAGE CONTENTS As shipped from the II Morrow factory, the Apollo SL50/60 package includes most items necessary for installation other than supplies normally available at the installation shop, such as wire and cable ties, and required input and output equipment.
Introduction OTHER REQUIRED MATERIALS The SL50/60 is intended for use with standard aviation accessories. External devices required for various installations are listed in the System Configurations section on page 4.

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.
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.
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.
Installation Figure 4 - Mounting Frame Assembly Figure 5 Cable Routing 12 Apollo SL50 / SL60 Installation Manual
Installation 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.
Installation 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.
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.
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.
Installation Clamp Nut Slip Washer Vee Gasket Step 1. - Slide clamp nut, slip washer, and vee gasket over end of coax. - Strip jacket as illustrated. 0.281 Step 2. Braid Clamp - Comb out braid. - Slip braid clamp on and push back against coax jacket. Step 3. 0.106 0.109 Contact Step 4. Step 5. - Fold back braid wires as illustrated, trim to proper length, and form over clamp. - Strip center conductor as illustrated. - Solder center conductor to contact.

Installation POST INSTALLATION CHECKOUT Once the unit is installed, complete the checkout procedure to verify proper operation. Refer to the User’s Guide for operating instructions. The steps that are not applicable to a particular installation may be skipped. A checkout log sheet is included on page 27 to fill out during the checkout procedure. Make a photocopy of the log sheet for ease of use if desired. The checkout procedure is broken into several groups.
Installation 2. Press SEL (the selection field will start flashing), rotate the SMALL knob to make the desired selection, then press ENT when complete. The available serial port configurations are included in Appendix E. Comm Radio Setup The Test Mode settings may also be used to preset the Microphone (Mic) Gain and the Receiver Squelch levels. Mic Gain Set the microphone gain for microphones 1 and 2 for values from 0 to 255. 1. In the Test Mode, rotate the LARGE knob to select "Gain - Mic 1." 2.
Installation GPS NAVIGATION CHECKOUT Switch on the SL50/60 in the normal mode to complete the this part of the checkout. The SL50/60 will go through a sequence of self tests. The SL50/60 requires a “seed” position, time, and date for the GPS sensor to know which satellites to look for. Once this is entered, it will be saved and updated automatically. If the SL50/60 is moved a great distance without being turned on, the seed position may have to be re-entered. Entering the seed position: 1.
Installation 131.200MHz 131.350MHz 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.
Installation 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.
