communication with the YJACK VIEW

 app and YJACK

 Series of Bluetooth® Sensing devices. If you are 

unsure if your older manifold has been updated or not, there are a few different ways to determine the 
firmware version of your P51-870 TITAN® and whether an update is required. During startup, the 
firmware version is displayed in the lower left-hand corner of the display on your P51-870 TITAN®. If the 
firmware version is V1.40 or earlier, your P51-870 TITAN® will need to be updated. Also, if you access 
the general settings screen on your P51-870 TITAN® 

by pressing the “gear” icon in the upper right

-hand 

corner of the display, manifolds with the updated firmware will display the firmware version, radio 

version, and serial number just above the “EXIT” button in the lower left

-hand corner of the screen. If 

you do not see this text above the “EXIT” button, your P51

-870 TITAN® will need to be updated. 

There are 2 separate firmware updates; one is for the P51-870 TITAN® radio which allows for 
communications with the YJACK VIEW

 app, and the other is for the P51-870 TITAN® circuit board, or 

USB Firmware, which allows for the P51-870 TITAN® to display the readings being broadcasted from the 
YJACK

 tools. If your P51-870 TITAN® is running on firmware version V1.40 or earlier, you can update 

both the radio and board firmware from either a Windows or MacOS computer.
