About the 100W-R and 100WP-R Endpoints
TDC-0951-001 100W-R and 100WP-R Datalogging Water Endpoint Installation Guide 4
Proprietary and Confidential
Battery Life
Powered by two non-replaceable, long-life lithium batteries, the 100W has an expected battery life of 20 years
when the endpoint operates in default Mobile or Fixed Network Operating mode. If the 100W endpoint is
programmed for Hard to Read Mobile Mode, the battery life is reduced to 13 years. To proactively indicate
the battery has reached a <10% useful battery life, a Low Battery flag is set to indicate impending battery
failure. Battery life is 15 years for the 100WP-R when endpoint cable lengths exceed 150 feet.
100W-R and 100WP-R Transmission Modes
The 100W-R and 100WP-R endpoints can be set to transmit in Fixed Network, Mobile High Power, Mobile
and Handheld, or Hard to Read Mobile, and Handheld Mode.
Fixed Network Mode. The 100W water endpoint transmits a high-powered NIM RF message every six
minutes and a contingency SCM RF message every minute.
Mobile and Handheld Mode. The 100W water endpoint transmits a medium-powered SCM RF
message every 9 seconds.
(Optional) Mobile High Power Mode. The 100W water endpoint transmits a high-powered SCM RF
message every 60 seconds.
(Optional) Hard to Read Mobile and Handheld Mode. The 100W water endpoint transmits a high-
powered SCM RF message every 30 seconds. The Hard to Read Mobile and Handheld Mode should only
be used for exceptionally hard-to-read applications.
Note The battery life is significantly affected in Hard to Read Mobile and Handheld Mode. You may use
the 900 MHz Remote Antenna to increase reading range.
An FCC license is not required to read 100W-R and 100WP-R endpoints.
100W-R Operating Modes
1. Factory Mode
100W-R endpoints ship from the factory in Factory Mode.
The endpoint's transmitter is off.
The endpoint's receiver bubbles-up to listen for a programming command.
100W-R encoder models attempt to read the register every hour.
Last good read and cut tamper flags may be set when a register is not connected.
If the 100W-R reads a connected register, the endpoint automatically moves to Run Mode (100W-R
only).
