6.2 DATA INTERFACE CONNECTORS
(Pubs Note: There will be separate sections for the AP and Remote in
the final book. Presently, only the AP is covered.)
Three data interface connectors are provided on the face of the Access
Point 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
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.
6.2.1 LAN Port
The LAN Port is used to connect the radio to an Ethernet network. The
transceiver will provide a data link to an Internet Protocol-based (IP)
data network through the radio network’s Access Point station. Each
transceiver 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 below.
