6.1 DATA INTERFACE CONNECTORS
Three data interface connectors are provided on the face of the trans-
ceiver. The first, the LAN Port, is an RJ-45 connector. The other two use
two DB-9 interface connectors that use the RS-232 (EIA-232) signaling
standard. Note that the connector for
COM1 Port is DCE (Female DB-9)
and the
COM2 Port is DTE (male DB-9).
The transceiver meets U.S.A.’s FCC Part 15, Class A limits when used
with shielded data cables.
6.1.1 LAN Port
The transceiver’s LAN Port is used to connect the radio to an Ethernet
network. The transceiver provides a data link to an Internet Pro-
tocol-based (IP) network via the Access Point station. Each radio in the
network must have a unique IP address for the network to function prop-
erly.
• To connect a PC directly to the radio’s
LAN port, an RJ-45 to
RJ-45 cross-over cable is required.
• To connect the radio to a Ethernet hub or bridge, use a
straight-through cable.
The connector uses the standard Ethernet RJ-45 cables and wiring. For
custom-made cables, use the pinout information below.
