General description of the OM1002+
solid state amplifier for 144 MHz VHF band
The OM Power model OM1002+ is a single band, solid state amplifier, designed for duty operation on 2 meter’s amateur band with all modes and no time limit. It is equipped with a new Freescale high rugged N-channel double MOSFET. This amplifier is characterized by compact design, small size and a low weight

LAN Connection
Remote unit is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found atwww.lantronix.com.
Default factory settings of XPORT are:
IP address: 192.168.1.233
Mask: 255.255.255.0
Gateway: 192.168.1.1
These are strictly default settings. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. There is no default user name or password. It is highly recommended to secure web interface with username and password.
For remote control over LAN and monitoring special software is needed. It is available free of change, it can be downloaded from the following address:
