Mitsubishi Datawall S-70HE75CA

prakash

Hi,
I am trying to control Mitsubishi S-70HE75CA datawall.Which is having 4 cubes is loop. First cube's RS-232 input port is connected to NI-4100 and output of first cube is coonected to the RS-232 input of the 2nd cube. Similarly for cube 2,3 and 4. I tried so many commands and combinations but not able to control even a single cube.

commands i am using are,

SEND_STRING dvDatawall,"$30,$30,$21,$0D" //power on

SEND_STRING dvDatawall,"$30,$30,$22,$0D" //power oFF

and i also tried

SEND_STRING 5001:1:0,"'00vP 0',$0Dh" //Power off

Also attaching the protocol file. Command string format and commands are mentioned on the page no 8 and 23 respectively.

anu suggesations plz

Yet another great protocol document!
In one section the command ID is 2 characters long and in another section it is 4 characters long.

I would try this:

SEND_STRING 5001:1:0,"'0001vP 0',$0D" //cube 1 Power off
SEND_STRING 5001:1:0,"'0002vP 0',$0D" //cube 2 Power off
etc.

it is unclear in my brief reading if:

SEND_STRING 5001:1:0,"'0000vP 0',$0D" //all Power off

would do a global power off for all the cubes in the chain. It might be worth a try.

Make sure that the cubes are addressed properly, check baud rates, check the wiring, Ya know all the usual suspects.
