Table 10.3 gives pinout information for the event marker/1PPS cable
which is supplied with the 5700 receiver. The event marker/1PPS cable
is only used with the 5700 connectors labeled Port 1 ( for event marker
output) and Port 2.

GPS Antennas and Cables
The antenna that a receiver uses to collect satellite signals is
sometimes called a GPS antenna to distinguish it from a radio antenna.
Radio antennas are used for communication between receivers and
external networks or systems.
Note – To use older models of antennas, such as the Choke Ring or
Micro-Centered L1/L2 antennas, with a 5700 receiver, you need to use an
antenna power adapter and an external power source for the antenna. For
more information, see Antennas, page 32.
