RX,Tx from HPC 300H

[naveen.rabelli]

Hi People,

Since the HPC 300 H controller has Rx, TX signals. I want to use these signals to my Onboard controller( that I have made, using a pic16f877a). My Onboard controller will capture real time data and display on the dash board+logs data RAM.

Have any one done this sort of experiment?, what is the format of the RX, TX signals, or how is the data sent.

Thanks again

I would need,

1.Message format( for Motor Speed, Motor Temp, Controller Temp, Bus Voltage, Phase Current, AH).
2.) Baud Rate Settings
3) Buffer Size of the message
4) Control Comands

Thanks

ok, guys this is the information I have.
I decided to monitor and analyse the data from controller to computer. and found that theres 64 bytes of message sent from controller.

the request message/command message to the controller is
81 7E 00 00 04 00 00 FF FC 0D CC CC CC CC CC CC    
 CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC   
 CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC   
 CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC   
message from the controller looks like this
7E 00 00 04 90 16 07 05 01 E5 FF DD 01 4A 01 D3     
 00 00 00 00 08 00 00 00 01 C2 00 39 FA 65 0D 75 
 56 5D 07 AC 39 1C BF 77 7F 36 4E EB D5 10 BF 9B 
 AD FB 7F FE 3D CE FE BF 6F DB 52 EB 17 CA EF F7   

Hex 07 05 = 1795 RPM; hex 01 E5 =485( 48.5) V; hex 01 4A=330( 33.0) deg C, controller temp; hex 01 c2=450(45.0) deg C, motor temp; hex 00 39 =57( 5.7 amp).....

I guess now, I have to find out the baud rates and check if I can make communicate with the HPC 300H..

Dear naveen,
I´m coming back to your post because I had stucked with the same issue.
See my post from 29.07.2014.
So the I/O on the Controller on Pin 14/15 is an UART not an USB instead.
This means ther is a USB to serial conv.  in PI-400
Witch was the software you had used for the connection , was it the MISVC software ?
Well I will give it a try using a UART but what confuses me is the manual that comes along with this.

regards joerg
