3.14.3 Diagnostics Port Operation
The Diagnostics Port is used to retrieve diagnostic or network management information about the
LYNX.sc radios by means of a computer connection. This can be accomplished locally or
remotely. Remote diagnostic port connections require either a modem (not included) connection
be made to the serial port, when a local dial-up phone line is available at a radio site, or by means
of direct connection through the AUX DATA port (Service Channel). The use of the AUX DATA
channel can provide a “network management” port where serial interface data is available from all
LYNX.sc radios in a network, provided that they are configured properly for this type of operation.
(This section and Section 3.14.4 describe this further).
The diagnostics port allows connection of either EIA standard RS-232 or RS-422 devices to poll
and receive status of the LYNX.sc radio. This serial port provides similar information to that which
is normally available to a local operator by means of visual alarms and status (front panel LEDs,
ADDRESS, DIP switch settings etc.), including voltage level measurements (such as RSL, PWR)
and alarm port (see Section 3.14.2) status. The diagnostics port can also provide extended
information including some advanced diagnostics and configuration information. Any information
that is available on the far-end terminal is also available at the near-end Diagnostics port (such as
far-end RSL, far-end alarms) by means of bridging the AUX DATA port (as described in Section
3.14.4). A DIP switch is used to define the command protocol for this port as shown in Figure 3-
22. The default setting is for TBOS commands (as described later in this section). The other
setting is for factory use only.
