If any additional modules are provided with the system, install them at this time using the instructions
provide with the modules.
2.20 Install the EDC-33P:
The EDC-33P (Engine Data Converter) converts all of the analog
engine signals into serial data which is output to the CGR display
via one wire (5V Serial). The EDC unit measures 4.5" long by 3.5"
wide by 2.2" high. There are three 37-pin D-sub connectors that
interface to the various probes, modules or direct connections to
the aircraft.
Mount the EDC on the inside firewall under the aircraft instrument panel or in an equipment bay with the
connectors pointing down. For a twin-engine aircraft the EDC can be mounted on the opposite side of the
firewall of the engine or in the cabin or equipment bay with the connectors pointing down. Use the holes in
the bottom plate of the EDC to mount the unit. Be sure you will have enough room to connect the three D-
sub connector wire harnesses to the EDC. Note: If you run out of channels on the EDC, a second EDC
may be installed and connected to the CGR.

When routing the EDC wire harnesses refer to the Top, Middle and Bottom "EDC Wiring Work Sheets"
found at the back of this manual. Insure no wires obstruct the freedom of travel of any controls.
Note: If the aircraft has an existing CGR-30P installed, the EDC-33P will already be installed in the
aircraft.
