Figure 12 – Setup for Insertion of an RMTR unit to the Network
The HHTR must know the serial number of any old RMTR that must be removed from
the network, the S/N of the new RMTR, and the S/N of the EMTR. Following the
configuration of the new RMTR, the HHTR can (without travel on the part of the
installer) acquire the EMTR, update it’s table, reacquire the new RMTR, cause it to
become “unsatisfied” regarding its upload, disconnect, and observe the traffic between
the RMTR and EMTR.
The new RMTR must be inserted in the acquisition list matrix in the appropriate column
(corresponding to the service type.) Within that column, the RMTR must be inserted in
the first available port. This would be the port with the smallest number with a zeroed
serial number.
4.2.4.2.3 EMTR Installation
At some point both RMTRs and EMTRs will be present in the same area. The Serial
Number of every RMTR to be assigned to the new EMTR must be entered, and the
service type of the RMTR known as well. Forced assignments can be made by writing to
the acquisition list table in the EMTR.
If the old EMTR is still functional, the original tables may be uploaded to the HHTR
prior to removal of the old EMTR. After EMTR replacement, the stored acquisition list
may be downloaded to the new EMTR and operation may resume. The installer may wish
to initiate an upload from a nearby RMTR to test the network.
4.2.4.2.4 Site Survey
An RF site survey is a characterization of a particular installation location from a radio
propagation stand point. It’s an essential element for proper operation of an RF data
collection system. Site survey includes a comprehensive test at the customer site that will
analyze the environment and check for any potential interference. Upon completion, the
study will determine best location of antennas and RMTR devices needed for optimal
coverage.
