RTU3 Issue

[afbezerra]

Hello,

The RTU3 worked for a few months, but now, can't activate the RTU3 (/dev/RS485-3). 

It´s a LM5 Lite+Ext(i.MX6).

Help please.

Lite+Ext(i.MX6) this is firmware, what hardware version is it? See side label.

Have the firmware 20240426

This is firmware version, I'm asking for hardware version which is on the side label of LogicMachine. Do not look for it in the software just check physically on the device.

I think is this:
LM5p2-KC
LM5M3v22BB-EX1CUv22-6ULv23BC-S8G

Run this script once. Then reboot LM. See if it helps.

Code:

require('i2c')

id = 'cr1'
b1, b2, b3 = id:byte(1, 3)

res = i2c.write(0, 0x50, 0x00, b1, b2, b3)
os.sleep(0.2)
res = i2c.write(0, 0x50, 0x70, b1, b2, b3)

It´s working again.
Thanks.
