Getting the Connect Failed when I try to run a transaction.

I tried two different routers with two different ethernet cords. I took over a business from a friend awhile ago and everything was fine up till last week outta nowhere it just gives me a connect fail. I never did any firmware patching or what not. Do help please.

I am looking for a user guide on how to use the Omni 3750 functions. Some how the one that came with it was misplaced. Where can I track one down?

My problem is when i connect my omni 3750 to my linksys wrt160nv3 all wireless is gone. Linksys people couldnt figure it out until i realized this happened when i connected the omni3750. My question is should I get a stronger router or is something wrong here?

I have several 3750′s that have recently started to act “funky.” I can boot a terminal and run a transaction just fine. So long as I run the next one within 5-10 minutes I can go on all day processing without a hitch, via ethernet/ip networking. Now, if I have a 10-15 minute dead period between transactions I will get a comm server error, and I will not be able to run another transaction until I reboot the terminal. I have only had this problem since Monday the 21st of Sept, 2009. Anyone have any ideas? I already tried to contact my isp. None of the computers on my network are having DHCP issues, and the firewall rules haven’t changed. I have moved the devices around to different segments of the network and still, no different. I am using Windows 2008 SBS as my DHCP server.

I have a netgear wireless router and have been unable to connect the 3750 unless I use static IP address and network information. I even tried going direct of of my DSL modem and still had no luck with DHCP. Since I already pulled out the netgear router, does anyone have another suggestions?

One thing that may help is to use static-dynamic DHCP setup in the router. This way the router always assigns the same IP address to the terminal, but the terminal can remain on DHCP.

I’ve good luck using this method with other finicky network components, and it may help for terminals as well.

I have two Omni 3750s. I was struggling to get them to work on my NETGEAR router (using ethernet) – much like many other posts here. I used these same terminals last year (seasonal business) with a different router and it worked well. So, I switched from the NETGEAR back to the BUFFALO that I used last year. Everything is working now.

I have monitored the IPs handed out by the routers DHCP server. It appears to drop the terminal from the list of clients after a few minutes of inactivity. I think that the OMNI is accustomed to requesting an IP from the DHCP for each transaction. I am guessing that the NETGEAR had trouble with that? Not sure, but the difference between the BUFFALO and NETGEAR with all other variables remaining the same is NIGHT AND DAY. Hope that helps someone.

Hi. We are trying to use an Omni 3750 in school stores. The school’s Internet connection has a firewall placed on it, and the district technology specialist says he needs to know the Internet port number the machine uses to open it up on the firewall. Does anybody know this port number it tries to access? Thanks!

I have a 3750 with a static IP address. I am able to ping everywhere, however I get an error that I cannot connect and connection failed. It gives me the error very quickly so I was thinking it may be with the machine setting? The other question is about opening a port on the router. What port needs to be open? I have tried port 443 and DMZ but still no luck.

Any help would be greatly appreciated.

We have a 3750 with a Static IP address. We get ” no line” when we try to run a transaction. We have checked the IP/comm mode and it is set correctly for Commserver primary and Dial backup. We do not have a phone line plugged in, just the Cat 5. When we unplug the cat 5, power down the terminal and replug cat 5, power up terminal and then try the transaction it goes through fine. After about 10-15 minutes later we try a transaction and were back to ” no line”. Any suggestions?
