Configuring the Serial Interfaces
Overview
To understand the operation of the radio system, it may be helpful to visualize the AP and the
Remotes as being in a single box, with the AP ports on one side and all of the Remotes on
the other side as shown below. In practice, the radios are typically separated by considerable
distances, but thinking of them grouped in the same box is helpful for this discussion.
Most data routing is done at the AP, so the majority of system configuration must also be
performed at the AP. The AP requires configuration of its local interfaces (Ethernet or Serial)
and knowledge of its remote interfaces, which are physically located at the Remote radios.
There are also a few parameters that may be configured at the individual Remote radios.
The AP includes an embedded terminal server that provides access to Remote serial ports via
an IP or serial connection at the AP. In this capacity, it acts as a gateway between IP and
remote serial devices (thus the name “serial gateway”), or a transparent over-the-air serial-to-
serial connection.
Serial-to-Serial Services
When the AP transceiver has remote serial units and is primarily passing RS-232 (serial-
based) traffic, it may be necessary to implement serial-to-serial interface transfers, as shown
in the lower part of the illustration above. Additional information for serial-to-serial wireless
networks is provided in chapter 5 of this manual.
