MOXA Nport 5100 Serial Servers

lbmorse — Fri, 06 Mar 2020 20:25:40 GMT

Have anybody ever used Moxa RS232 Servers to control shutter programming using Isadora? I use them when I'm using Watchout, because there is a more robust set of settings you can change via RS-232 with Pansonic projectors than with straight TCP/IP control... specifically you can change the Shutter Open / Shutter Closed speed on the fly.

In Watchout you send a text string containing the RS232 control commands to the Moxa box via a TCP send message, and then the MOXA box converts the TCP string to a serial command for the projector. I've tried using the TCP Stream Control actor to open a connection to the MOXA box, and then sending the string command through that stream using the TCP Send Data actor, but to no avail.

Has anybody every had any success with this?

That's a lot to keep track of

Definitely one of the reasons that I haven't futzed with my Arduino in a while ;)

@Woland

Sage advice, Lucas. And nice pun too. I'll start experimentations tomorrow, and keep you in the loop!

Well, first take a look at this page:

http://www.commfront.com/RS232_Examples/CCTV/Pelco_D_Pelco_P_Examples_Tutorial.HTM#1 There are some example command strings under "Pelco-D command string examples" You can just double click the Send Serial actor, and paste one of these examples into the dialog box. Then trigger the actor to see if the PTZ responds. If it does, then you'll have to do some work to figure out the messages you want to send. The biggest difficulty is that this protocol requires a checksum -- and, unfortunately, Isadora cannot calculate this for you directly. So it's going to take a bit of work to implement this protocol if you need to go beyond simple messages that are fixed, like the ones in the example above. Best Wishes, Mark
