SEND_COMMAND Feedback for Solecis SDX510M?

fogled@mizzou

We've been deploying Massio systems with SDX510 switchers, and it's been working pretty well. But we also want to control these units from regular NX/NI controllers running our own code. The problem I've run into is that the SEND_COMMAND function never returns anything, even with a query. It acts on commands sent to it, but I can telnet into the switch, do a

send_command 5201:1:0, "'?VIDIN_AUTO_SELECT'"

...and I get nothing returned. Documentation claims there should be a response.

To control these with my own code, I'd like some feedback. I can't find any "Verbose" settings to change to get feedback from the switch.

Anyone know how to get feedback from these things?

Thanks,

Joe Hebert

Where are you looking for the feedback? Are you trapping for feedback in the COMMAND: handler of the DATA_EVENT of the device?

the manual wrote:

Requests setting for the Auto Select mode for the video input signal on the switcher.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_AUTO_SELECT'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_AUTO_SELECT'"
Returns a COMMAND string of the form: VIDIN_AUTO_SELECT-<status>.

I haven't tried that yet, this is via a direct telnet session into the switch. Does it just not show up there, it only shows up in the COMMAND handler in a controller device?

I have no experience with the product, just going by what the manual says. Aside from code, feedback should also show up in Notifications in Netlinx Studio. Don?t know about telnet.

True, the replies to send_commands in telnet will only return in data_events as data.text. I find it helpful when debugging/testing to add a section like this:

Data_Event[dvDeviceBeingTested]
{
  String: Send_String 0,"'String reply from dvDeviceBeingTested: ',data.text"
  Command: Send_String 0,"'Command reply from dvDeviceBeingTested: ',data.text"
}
