7.3 Crimping GPS Cable
The third-party Global Positioning System antenna (GPS) connects to the BSDU's 15-pin D-type
port. Therefore, the cable from the GPS needs to be crimped to a 15-pin D-type male connector.
Airspan recommends using the Daniels AFM8 (M22520/2-01) crimping tool for crimping the GPS
cable to 15-pin D-type connectors.
