6.1 DATA INTERFACE CONNECTORS
Two types of data interface connectors are provided on the front panel
of the transceiver—an RJ-45 LAN port, and a DB-9 serial port (
COM1)
,
which uses the RS-232 (EIA-232) signaling standard.
The transceiver meets U.S.A.’s FCC Part 15, Class A limits when used
with shielded data cables.
6.1.1 LAN Port
Use the transceiver’s LAN port to connect the radio to an Ethernet net-
work. The transceiver provides a data link to an Internet Protocol-based
(IP) network via the Access Point station. Each radio in the network
must have a unique IP address for the network to function properly.
• 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 in
Figure 6-1 and
Table 6-1 .

6.1.2 COM1 Port
The
COM1
serial port is a standard DB-9 female connector. Connect a
PC to the transceiver via this port with a DB-9M to DB-9F
