Tip of the Day 46: eDART Lynx Port Limits

 

 

There seems to be some confusion about how many sensors each Lynx port on an eDART can handle. Here is the definitive word.

 

    • Each Lynx port can read up to 30 Lynx devices – That’s 60 total on a 2 port eDART.

 

 

 

    • Of those 30 on each port, 14 of them on each port can be output devices: OR2 (“Output Relay 2”) or AO (“Analog Output”)

 

 

 

    • The number of “channels” (e.g. 4 in the Lynx Quad Temperature or 2 in OR2) does not count. Just the number of Lynx devices.

 

 

Additional Points

 

    • The power supplies in the eDART are designed to power all 30 on each port (up to a point). They supplies 2 amps on each Lynx port (4 total).

 

 

 

    • Dividing the sensors equally between each port gives the best sample rates. Usually we encourage one port to go to the mold and one to the machine.

 

 

 

    • This spreadsheet lets you enter the number of each type of sensor on each port and then it computes the sample rate and current load.
