SV-XPNDR-261/262 Installation, Configuration, and Testing
11-14 SkyView System Installation Guide - Revision R
Antenna TNC Connector
This section describes the technique for attaching the antenna cable to a TNC connector. A TNC
connector is not supplied with the SV-XPNDR-261/262. The SV-XPNDR-261/262 has a female
TNC connection. Therefore, you will need to source a male TNC connector that is compatible
with the antenna cable type that meets your aircraft’s needs.
A dual crimp style TNC connector can be completed using a wide range of commercial crimp
tools (for example the Tyco 5-1814800-3). The die apertures for the inner pin and the outer
shield should be approximately 1.72 mm and 5.41 mm respectively.
 Strip back the coax cable to the dimensions in the table, as shown in the diagram below.
Slide 25 mm (1 inch) of heat shrink tubing over the cable.
 Slide the outer crimp sleeve over the cable – it must go on before securing the center
contact.

 Crimp the center contact to the cable.
 Insert the cable into the connector – the center contact should click into place in the body,
the inner shield should be inside the body of the connector and the outer shield should be
outside the body.
 Crimp the outer sleeve over the shield.
 Slide heat shrink tubing forward (flush to connector) and heat to shrink the tubing.

Serial Port Setup
Before the TRANSPONDER SETUP menu can be accessed, the SV-XPNDR-261/262 needs to be
set up as a serial device on each SkyView display on the system. To accomplish this:
 Go to SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP.
