100W/100W+ and 100WP/100WP+ ERT Module Transmission
Modes
The 100W/100W+ and 100WP/100WP+ ERT module 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/100W+ and 100WP/100WP+ ERT module transmits a high-powered
NIM RF message every six minutes and a contingency SCM+ RF message every minute.
• Mobile and Handheld Mode. The 100W/100W+ and 100WP/100WP+ ERT module transmits a
medium-powered SCM+ RF message every 9 seconds.
• (Optional) Mobile High Power Mode. The 100W/100W+ and 100WP/100WP+ ERT module transmits
a high-powered SCM+ RF message every 60 seconds.
• (Optional) Hard to Read Mobile Mode. The 100W/100W+ and 100WP/100WP+ ERT module
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 100W/100W+ and 100WP/100WP+ ERT module's battery life is significantly affected in hard
to read mobile mode. You may use the 900 MHz Remote Antenna to increase reading range.
An FCC license is not required to read 100W/100W+ and 100WP/100WP+ ERT modules.
100W/100W+ ERT Module Operating Modes
The 100W/100W+ ERT module has three standard operating modes.
1. Factory Mode
• 100W/100W+s are shipped from the factory in factory mode.
• The module's transmitter is turned off.
• The module's receiver is bubbling-up to listen for a programming command.
• 100W/100W+ encoder models will 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/100W+ reads a connected register, the module automatically moves to run mode.
