MMSC Debounce Setting
MMSC Debounce Setting
How are command changes sent to the mmsc? I'm trying to increase the debounce rate for the buttons on the mmsc, I get 2-5 hits per press and I'd like to increase the debounce rate. I found this:

MMSC is connected to 2 or more MSC ports; MMSC only used with 2 or more

MMSC display keypad debounce problem (FYI 100882 100884 100737) 
MMSC>r 1 MMSC>setenv DEBOUNCE_DELAY 200000

Do I have to connect to the mmsc through the 8-pin din?

RE: MMSC Debounce Setting

I had exactly the same problem.
The following did work perfectly for me:

1. Disconnect the DIN8/DB9 cable of the Graphics Rack

2. Connect the DIN8 on the TEST port of the MMSC (I tried with other ports but it wasn't successful -> to be understood)

3. Connect the DB9 on your computer/laptop

4. Set serial connection on Putty/MobaXTerm/HyperTerminal with these parameters:
- Baud rate: 9600
- Data bits: 8
- Stop bits: 1
- Flow control: Xon/Xoff

5. Press Ctrl+t
MMSC prompt should be displayed

6. Now you can enter the debounce delay command

I found a really nice and useful post here:
