Are you sure that you are not hitting this defect? http://www.cisco.com/en/US/ts/fn/634/fn63496.html -Keith From: Cisco Developer Community Forums [mailto:cdicuser@developer.cisco.com] Sent: Thursday, March 29, 2012 2:03 PM To: cdicuser@developer.cisco.com Subject: New Message from Stephanie McQuown in Digital Media Suite API - Digital Signs API Forum: Security Certificate Multiple DMPs Stephanie McQuown has created a new message in the forum "Digital Signs API Forum": -------------------------------------------------------------- We are a control system software developer with a customer with about 30 DMPs. All DMPs were not communicating properly, so we thought we would need to update the security certificates. After updating one certificate, about 10 of the DMPs started working. Updating a second unique certificate fixed about another 5. We have read here in the forums that each DMP would need a unique certificate. Any idea why several DMPs would start working when a single certificate was updated? Also is there a way to install a root certificate that would update all the DMPs? -- To respond to this post, please click the following link: or simply reply to this email.

RE: How to send RS-232 commands programmatically from a DMP-4400?

The difference is that when you send the message through the DMP admin interface, you just send the plain hex string. If you prefix the hex string with "rs232.tx_hex=", it does not work. If you leave out the "rs232.tx_hex=" part, the command works successfully. The only time you need the "rs232.tx_hex=" part is when you are creating DMM Advanced Tasks.
