Installation Guide

Network Mode
In Network Mode, the module reports four interrogation cycles daily. Each interrogation
collects six hours of 3,840 buckets of interval and event data. Interval data is configurable
from 1 minute to 1 hour (for example, 160 days of hourly data or 40 days of 15 minute data).
Interval options are 5, 15, or 30 minutes.
Note: Interval data configuration is dependent on the module's firmware version. See
Firmware Functionality on page 1 for more information.
The Cellular 500W Pit Module also sends a local access beacon message every 60 seconds
that allows users to gather contingency readings locally when needed.
Caution: If you perform a switch to Network Mode or switch to Mobile Mode
operation, it results in a loss of interval data.
The Cellular 500W Pit Module does not require an FCC or ISED license when operating using
the 902 to 928 MHz in the ISM frequency band .
When using the cellular modem, the Cellular 500W Pit Module operates in Band 13 (777-787
Tx and 746-756 Rx) and Band 4 (1710-1755 Tx and 2110-2155 Rx) as defined by the 3GPP
LTE standard.
Operating Modes
The pit module has the following operating modes.
■
Factory Mode
–
Pit modules ship from the factory in Factory Mode.
–
The pit module's transmitter is off.
–
The pit module's receiver listens for a programming command.
–
The pit modules attempt to read the register every hour.
–
Last Good Read and Extended event or alarm flags may be set when a register is not
connected.
–
If the pit module reads a connected register, the pit module automatically switches to
Run Mode.
■
Audit Mode
–
Audit mode reduces the normal read latency time associated with standard modes of
operation and is often used after initial installation.
–
This mode is useful in network installations where the normal bubble rate is very slow.
