Operating Mode
The NIC will write messages to the meter LCD, which indicate the NIC operating
mode. These messages are intended to appear on the ALT scroll list.
Table 9.2 NIC Operating Modes
Trace Route
With the new meter installed in the system, the ability of the system to interact
with the NIC can be tested with the trace route command.
Testing Communication with a Meter in the Field
Use the headend software to select the NIC target and allow it to return a response
along multiple DCU pathways. The system will report the message latencies along
each path along with the signal strengths. Compare these signal strengths to the
performance specifications in Product Specifications on page 11 and to the DCU
receiver performance specifications. The strongest return pathway should be well
above the DCU’s sensitivity limits described in the DCU Maintenance and
Operation Technical Manual. Other pathways may be near the sensitivity limits.
DCUs which do not appear in the report were too far away to hear the NIC’s
response.
Message LCD Text Meaning
Hot HOT
The NIC has suspended any RF transmission
because it sensed a high operating
temperature. It can still receive messages,
just not transmit them. The NIC will revert
to another mode when it cools down.
Quiet QUIET
The NIC has been placed in a radio-silent
mode for the purposes of meter calibration.
Ship SHIP
The NIC has been placed in a “ship mode”
which will cause it to suppress last gasp and
restoration messages, as well as register in
the network after a power down / power up
cycle.
Shop SHOP
The NIC has been placed in a “meter shop
mode” which will cause it clear certain
histories, suppress last gasp messages, and
register in the network after is power
cycled.
Secure SECURE
The NIC is operating normally and has
security enabled.
Run RUN
The NIC is operating normally and has
security disabled.
