10/100 Ethernet Connector
The 10/100 Ethernet connector provides the LAN or WAN connection for the IP-223.
Serial Connector
The serial connector (DB9) is used for either of the following:
• To program an initial IP Address into the IP-223 unit, if the IP Address cannot be programmed through the
Ethernet port on the installed system.
NOTE: To communicate with HyperTerminal, the jumper setting must be RS-232.
• To provide serial communication to various radios. Both radio (or line) 1 and radio (or line) 2 are supported on
this connector, with the appropriate splitter cable.
NOTE: You must adjust the position of the jumper, on J35 when using line 1, or on J26 when using line 2, according to
the serial connection type for the radio interface shown below. See “Jumper Positions” on page 25 for more
information.
