1.2. W nertial GPS The wireless LAN antenna on the RT Range should be removed It may be necessary to disable the wireless LAN in the RT Range to avoid Ethernet conflicts During tests at OxTS it has been possible to run both the RT Range wireless LAN and the RT XLAN at the same time but this cannot be guaranteed See the next section on Error Not a valid bookmark self reference Disabling the RT Range s wireless LAN It has not been necessary to disable the wireless LAN in the old style RT Range cases in order to use the RT XLAN However there may be times when the internal wireless LAN will conflict with the RT XLAN If this happens then the internal wireless LAN in the RT Range should be disabled If the internal RT Range wireless LAN is disabled then clearly label the outside of the box so it is clear that it has been disabled It is very difficult to diagnose a problem with the wireless LAN so clear marking is essential In order to disable the wireless LAN in the RT Range it is necessary to disassemble it The instructions for disassembling both the RT Range Hunter and the RT Range Target are the same These instructions can also be used to enable the wireless LAN if the RT XLAN is no longer being used To remove the front panel from the RT Range Hunter carefully undo the 4 screws on the front panel These usually require a 2mm metric Allen hex key some RT Range systems have been supplied with screws that require a 2 5mm
3. Note Connections to the standard RT Range system are described on page 13 of this manual Although the RT XLAN is weather resistant we strongly recommend that the N Type connector from the device to the antenna is covered with self amalgamating tape to help protect it from moisture When using the RT XLAN with a standard RT Range system or standalone with just the RT it will be necessary to use the Y cable converter kit ordered separately More information about this can be found on page 13 of this manual 10 Oxford Technical Solutions RT XLAN User Manual Inertial GPS Configuration There are no user configuration options on the RT XLAN However it is important to make sure that each unit is compatible with the other units in the environment There are several items to consider e Each RT XLAN will have a label showing its configuration The RT XLAN labelled Base should be used on the Hunter vehicle e The RT XLAN labelled Client should be used on the Target vehicle There cannot be two RT XLAN base units in the same environment There must be one RT XLAN base unit The RT XLAN client units will not communicate with each other unless there is a base present Each RT XLAN has an IP address All the units being used must have different IP addresses Normally the IP address will be in the range from 195 0 0 170 to 195 0 0 175 It is possible to order different IP addresses from OxTS This IP
