appropriate scaling factor. The installer must also indicate the number of dials on the
meter. The CCE can use this information to recreate the dial face reading as it is in the
field.
5 CCE SUPPORT
a. If any type of RMTR or appropriate EMTR installation (or change-out) occurs, the
installer is required to update the Acquisition Table in the EMTR. This in turn causes
a flag to be raised in the RCE Inbound Header, and a bit in internal Register #34,
Indicator Alarm to be asserted.
b. The CCE reads the “Port Quantities by Service” internal register #751, and
determines how many ports are in use for each service.
c. The CCE can then self-discover the Serial Number of the RMTR for each port
assignment. The CCE reads the MFG_ID registers (#800-831) and saves the
information in a database for future reference.
d. Other associated information such as RMTR configuration data can be obtained by
additional register reads.
The installer should have independently recorded the serial numbers of any equipment
added or removed to the system. The CCE must support the process of determining the
presence or absence of serial numbers. If equipment is added and doesn’t subsequently
appear in the network, the cause must be evaluated. Some possible reasons are:
1. This is the first equipment (either RMTR or EMTR) in an area. It takes both in the
same area for communication to occur. (A note by the installer should indicate
this.)
2. The equipment is out of range. (An on-site test should have confirmed proper
operation before the installer left.)
3. Unreliable communications. Perhaps RF is not the right solution for this site.
4. Equipment failure. (This should be exceptionally rare in light of the stringent
manufacturing QA and the on-site test by the installer.)
The CCE must compare the list of all units that have been installed to the list of units that
are operational. If the lists are not the same, it needs to be investigated.
The CCE should be able to produce an acquisition list relationship table for use by the
installers. If a given RMTR is to be swapped out, the list allows the installer to reproduce
the (forced) ling-assignments in the original equipment.
6 FCC COMPLIANCE STATEMENT
a. Changes not expressly approved by Distribution Control Systems, Inc. could void
the user’s authority to operate the equipments.
b. Note: The equipments have been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. These equipments generate, use and can radiate radio
