5.1 Data Interface Connectors

Three data interface connectors are provided on the face of the transceiver. 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
DB-9).

POTENTIAL
The transceiver meets U.S.A.'s FCC Part 15, Class A limits when used with shielded data cables.

5.1.1 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 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
• 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 5-1 and Table 5-1.
