DSC IT-100 baud rate

2 years ago in Devices / DSC • updated by 2 years ago • 5

Hi guys,

The default baud rate comes as 9600 for the DSC IT-100. Do you have any tips on how to change it to 19200 for virtual keypad?

Could it be done using the key pad PK5500?

Thanks,

Calin

I've found this on a manual. I'm not experienced with DSC, so I'm not very helpful:

The baud rate can be changed by the application by sending a Baud Rate Change (080) command. The IT-100 responds with the Baud Rate

Set (580) command to confirm the change. Recommended Baud rates are listed below.

But I'm afraid I don't know where you can do this step...

Thanks Ricardo, that's where I got stuck. I don't know if these commands have to be initiated on the keybus side or on the RS-232 side of the IT-100 and how to be sent. I contacted DSC and they don't support IT-100 , they provide only the manual. They were supposed to check among their engineers and get back to me but no response.

I guess Comfort Click would know since they've integrated it and it's noted on their website:"NOTE: Baud rate should be set to at least 19200, when using virtual keypad. Before changing the baud rate make sure that DSC node value Connected is set to True."

Wait a second... IT-100 is a product from DSC, and they don't provide support? What the heck is going on?

On the manuals, it refers to the "IT-100 Developer's Guide", where it says what I've posted previously.

I assume, according to the documentation, that the command to change the baud rate must be sent from the ComfortClick to the unit. I believe that this can probably be done by creating a "Basic" device, and create the commands to be sent to the unit (send the 080, confirm the reply, and send the 580 command).

Best regards
