For a project of mine, I am using a MHC0150MN06F3J013FD sensor from tempotronics with the source address of 253. I can reach this sensor using the JFIN channel on this source address with PGN65535. What I would like to do is add another of these sensors which have a standard source address set to 253 and change that source address to, for example, 252. I have looked into the datasheet of the sensor and it seems this should be done by changing Byte 9 on PGN 65240 using a JFOUT channel. My problem however is that I cannot reach Byte 9 because of the maximum length of 8 Bytes per data package of the J1939 protocol. In the IQANDesign datasheet, I can see the multi-packet option available (to send a second package for the source address) for the JFOUT function but in my IQANDesign 5 it does not show up in the property manager. Am I looking in the wrong direction here? Is there a standard function for changing the source address of a connected device?
Thank you in advance!
