*RTAF, RTAFH & RTHD sensors have been discontinued and replaced by the RTAFHD3 sensor. Some
Geist R-Series devices may
require a firmware update to allow for proper compatibility with the new RTAFHD3 sensors.
If your Geist R-Series device is using firmware version 2.xx you will want to make sure you are using
firmware version 2.94 or newer.
If your Geist R-Series device is using firmware version 3.xx you will want to make sure you are using
firmware version 3.5.0 or newer.
Please contact Geist Support at 800-432-3219 if you need assistance locating your current version or
upgrading to the new firmware version
RTAFHD3 Compatibility
The (G)RTAFHD3 sensor cannot be utilized in combination with the discontinued (G)RTAF and
(G)RTAFH sensors or (G)RTHD sensors built prior to 2010. If you desire to add (G)RTAFHD3
sensors to an existing installation currently utilizing incompatible sensors, please contact
Customer Service for installation options.
Connecting Remote Sensors
Plug-and-play remote sensors may be attached to the unit at any time via the RJ-12 connectors
on the face of the unit. A splitter may be used to add additional sensors to the GRSMINI-P.
Each sensor has a unique serial number and is automatically discovered and added to the web
page. Up to sixteen sensors may be connected.
The display order of the sensors on the web page is determined by the serial number of each
sensor. Friendly names for each sensor can be customized on the
Display
page.
Note:
The sensor uses Cat. 3 wire and RJ12 connectors. Wiring must be straight-through: reverse polarity
will temporarily disable all sensors until corrected.
Note:
The sensors use a serial communication protocol and are subject to network signaling constraints
dependent on shielding, environmental noise, and length of wire. Typical installations allow runs of up to
600 feet of sensor wire.
Data Logging and Display
All data collected by the unit can be graphed. The
Logging
page allows the user to select graphed
content to be logged. Selected sensor values are logged into the data file at a rate of one point per
minute. The number of selected sensors determines the maximum data logging time span. This
period is calculated and displayed on the
Logging
page. The oldest data will be deleted when the
onboard memory fills up in order to make room for new data.
