Figure 11: TeraHop Networks Ethernet Network Cabling
Since the Ethernet Switch has MDIX capable ports, crossover cables are not required.
Use straight through cables for all connections. When determining length, leave adequate
extra length to account for future relocation or connector repair.
1. Locate the Gateway Server mobile PC. Connect a CAT-5 RJ45 terminated cable from
the server Ethernet jack to a port on the Ethernet switch.
Note: the specific port used is not critical. All ports are equivalent from a connection
viewpoint.
2. Locate the MMR System mobile PC. Connect a CAT-5 RJ45 terminated cable from
the server Ethernet jack to a port on the Ethernet switch.
Note: the specific port used is not critical. All ports are equivalent from a connection
viewpoint.
3. Locate the THN Gateway Router. This unit is normally located on the roof of the
vehicle on a retractable mast. The outdoor rated Ethernet cable that is provided is
equipped with the correct weatherproof boot for the router end of the cable. Make
sure the boot is properly secured to the GR's connector.
