Description
Helios is a java based diagnostic tool that will allow you to view all data link messages on 500k J1939, 250k 1939 and 1708 data links. What follows
is step by step on how to:
• Obtain a Helios Capture in Vector Format to attach to a case file.
◦ The Helios capture must be zipped to add to the case file.
• Use Helios as a diagnostic tool to view Signals, Faults and more.
Helios is not an effective sniffer. When a module stops communicating it does not "drop off" the sniffer, it stops counting. This can make it
difficult to understand if a module is no longer communicating.
Obtaining a Helios Capture in Vector Format
1. Helios is now available for 500k Baud J1939. You can download the program by going to IK2700065 ‐ EZTech Download Center. Helios for 500k
is item E22 in the Download Center.

rate from the Tools Menu for the vehicle you are working on.

before, or you are using a different com link, you will need to select your com link from the Tools menu. ‐ Figure 3. If you are using Helios for
500k you will need to select the baud rate you want to record.
