TWC Manager Power available for all TWCs: None, Slave available, but no power

[revgazza]

I am trying to get TWCManager working. The data connection works as the slave is found. Switch is set to 'F'.
I have also set up an API to get solar data from effigy engage hub and edited the script as appropriate.

However, this is what I am getting when I connect to my TWCManager:

Power available for all TWCs: None
TWC 9119: No power available.

I appear to get heartbeats, but nothing else happens.
Also, I have a red light slowly flashing on the TWC.

Any assistance would be appreciated.

This is what putty displays..

Hi @revgazza,

Does this part just repeat continuously:

It seems that you have a comms problem of some sort, it looks like your TWCManager can see the slave TWC, but the slave TWC isn't getting your replies correctly.

First thing I would check is the connections - is there any issue with the TX connection (from your RS435 terminal)?

Thanks ngardiner.
I am away at the moment, but I'll have a look at that. The RS485 might be the issue. I purchased it from Jaycar Electronics. It is actually a USB Port to RS-485/422 Converter with Automatic Detect Serial Signal Rate. I'll check it with a cro.
