Transmitted signals appear on the center contact, and the outer shield is ground
for the 75-ohm coaxial cable you attach to the TX DIN 1.0/2.3 connector.
Received signals appear on the center contact, and the outer shield is ground for
the 75-ohm coaxial cable you attach to the RX DIN 1.0/2.3 connector.
To mate the 45-degree cable connector on to the 1.0/2.3 SPA connector, ensure the sliding barrel on
the connector is pulled back and carefully slide or push the connector on to the mating part on the
SPA board. Then, push the barrel forward.
To unmate and remove the 45-degree cable connector, gently push the rear of the connector and
simultaneously pull the sliding barrel of the connector towards you with your other hand. After the
connector is unmated, you can remove the cable from the SPA.
