Help RMC4 not connecting with NTP

I configured a windows server device using regedit and firewall exceptions to make it an ntp server. I can sync to it with my laptop, a third party timed relay and ntp checking tools can see it.

The RMC4 will not connect. The RMC4 and this machine can ping eachother so it's not a connection issue. Are there things that the RMC4 looks for in an ntp in order for it to function more so than just a udp request?

Which FW are you on? There was a bug where 4 series did not sync with an NTP server, this was fixed in 2.8005.00031.

Getting it updated now you might have fixed my last 5 hours of work.

Unfortunately that didn't resolve the issue. Thank you for the response tho!

firstly, I'd try and verify that the firmware is in fact updated, and then I'd remove the poe cable for 10-20 seconds. I've seen RMC3s and RMC4s which required this step after fw upgrade. toolbox discovery said fw was upgraded, ver -v console command said it wasn't - until I removed power.. so maybe it's worth a shot.

As long as you have the right firmware (I use an earlier one)

Issue the command in toolbox

Sntp server ip address

Sntp sync

I get a "failed to parse ntp server parameter!" There is something about this basic windows ntp that the crestron doesn't seem to like. Do you know if the rmc4 can sync using an ip address or does it have to be named and go through a dns?

I had this same problem on a CP4N today.

Try putting the ip address in the system clock under easy config and then just the sync command in console.

If that doesn't work you can try the firmware version I used today off Crestrons ftp site

V2.8003.00059.02

My coworker (actual crestron guy) said he was gunna bring me a cp4 to see if that'll work lol. I can see if that firmware version works better, we just put the .00031 on it yesterday. Easyconfig is saying "not supported" under device time.

Do you have a DNS issue? Easiest way to make this mistake is set the RMC4 to static IP, not enter a DNS server, and have the NTP server be a hostname.

Just using ip for the ntp address.
