User Manual Part 2

Lynx.GX Installation and Management
There are two external input alarms, independent of the relay outputs available. From the SysCfg page, you
can set whether an open or closed condition produces an alarm.
See the table of alarms in “Log Tab: Viewing Status and Alarms” on page 62. See “Connectors and Pin
Assignments” on page 46 for ALARM port connector information.
NMS1 and NMS2
There are two Ethernet 10/100 Base-TX connections (both switched) for access to the Network Management
System (NMS) using SNMP, HTTP, or Telnet. Both of these connections auto-negotiate speed and duplex,
and auto-sense MDI or MDI-X connections. On GX radios, the two 10/100BT ports are identical, and can be
used to daisy chain the NMS connections between units at a hub location or to connect to other local Ethernet
devices. See “Providing a Contiguous Management Link” on page 33.
AUX DATA
This is a serial interface port (RS-232) using an RJ-45 connector, supporting speeds from 2400 to 19200 baud
(set through the NMS). This allows auxiliary serial data connection from one end of the wireless link to the
other, completely separate and independent of the main bearer channel. It can be used for separate data
connections for serial devices. See “Connectors and Pin Assignments” on page 46 for AUX DATA port
connector information. Note that the aux data rate must be configured using the Web interface before use.
VF (Voice Frequency)
This RJ-45 connector is used to link two radios at a repeater site for Orderwire operation or to connect to an
external Orderwire system. This allows Orderwire calls to and from any point in the network that is connected.
The circuit is a 4-wire audio (2xTX and 2xRX) configuration. All phones off-hook hear and participate in the
call (behave as a ‘party line’). The NMS provides Orderwire addressing capability for individual radio terminal
signaling. See “Connectors and Pin Assignments” on page 46 for VF port connector information.
