double shielded wires then ground both shields at the GPS/VLOC/ACU with pigtail as
short as possible.

RSM Wiring
The EFD1000 E5 to RSM wiring run is made with a single cable seven (7) conductor
shielded wire. M27500-A24SD7T23 or M27500-22TG7T14 seven (7) conductor shielded
cable can be used. Cable runs longer than 35ft are not recommended.
Ensure that a trap or drip loop is provided to prevent fluids or condensed moisture from
running into wires and cables dressed downward to a connector, terminal block, panel, or
junction box. See AC 43.13-1B Chapter 11.

7.2.6.2
Assembly using M27500-A24SD7T23 Cable
Terminate the aircraft side of the RSM wiring with the Hirose circular connector from
installation kit as shown in Figure 7-2 below. Due to the compact design of the Hirose
connector it may be easier to solder the wires to the solder cups on the bench versus
inside the tail of the aircraft. Use a fine tip soldering iron for this procedure.
1)
Pass the cable through the hood and metal cover. Strip back the insulation to expose the
shielding and wires with the dimensions that are shown.
2)
Stake the metal clamper to the shield in the location shown. A hexagonal crimper such as
the ones used for BNC Coax connector assembly work can be used to crimp it to
approximately 5.2mm outside diameter.
3)
Assemble the two pieces of the connector such that the ring retains the solder cup piece.
Discard the washer as it is not required.
4)
Solder the seven (7) 24 AWG wires to the connector.
5)
Thread metal cover onto connector.
6)
Insert screw into metal cover so that it indents into metal clamper.
7)
Put hood over metal cover.
