WR44 Series Installation Guide

ANT. WLAN	This male SMA connector is used to fit the wireless LAN diversity
(Aux.)	antenna for improved receiver sensitivity.
	(Models with WLAN option fitted only)
LAN 0, 1, 2, 3	The socket labelled LAN is used to connect the unit to a
	10/100Base-T LAN using the 2-metre STP (Shielded Twisted
	Pair) cable supplied or a suitable alternative. This port is auto-
	sensing for speed and wiring (straight-through or cross-over). To
	comply with EMC requirements it should not be used with non-
	STP cable.

Reset button

This is located on the underside of the unit near the front (just behind the DTE LED), and can be accessed through a 2.5mm hole using pencil tip or similar implement. Holding the reset button down gently for 5 seconds when the unit is powered up and operational (i.e. has finished booting), will cause the factory settings to be loaded into flash before and then re-boot. During this time you will see a pattern of alternating LEDs flashing followed by the normal boot sequence. Do not remove power from the unit during this operation, as corruption of the flash memory may occur.

1.3Optional features.

WR44 series routers are available with a variety of hardware options. At present these are:

1 x ASY	Provides an additional asynchronous serial port using a 25-way D
	connector
3 x ASY	Provides three additional asynchronous serial ports using RJ45
	connectors.
1 x SYN	Provides an X.21/RS422/RS232 synchronous serial port using a
	25-way D connector.
1 x GPS	Provides GPS geo-location capability.
1 x ISDN BRI	Provides an ISDN Basic Rate Interface (BRI) via an RJ45 socket.
	This can be configured either as a TE (terminal endpoint) or as
	NT-1 (network termination). The option also includes an additional
	asynchronous serial port via a second RJ45 socket.
Telemetry 1	General Digital I/O Card.
