Email Issues
If you are having trouble connecting to your networked 920i, the problem might be caused by IP addressing or
network firewall issues. First, see the below diagram for a typical network setup:
One of the most common problems is a firewall (or multiple firewalls). In many cases, the firewall simply
doesn’t know the Ethernet address of the 920i. Thus, it is rejected and can’t make it past this point. The remedy is
a firewall configuration by the company’s IT department to add the 920i’s address to the device.
Other common problems occur within mail servers. Local email clients use the Post Office Protocol version 3
(POP3), an application-layer Internet standard protocol, to retrieve email from a remote server over a TCP/IP
connection. If the 920i’s IP address isn’t allowed to relay (send) mail, the message could be rejected. The email
server needs to be manually configured to allow the 920i to do this.
Additionally, the receiving mail server might get an email from the 920i and go back to ask the network’s mail
server if it, in fact, sent the message, which would make it allowable. Since the 920i sent the message, the mail
server replies with “No, it’s not from me” and the email is discarded. Again, a typical IT department is fully
capable of correcting this.
There may also be multiple spam filters existing within the network, any one of which could interpret the
message as coming from a fictitious address. The address from which the 920i sends an email must be added to
the server and added to any third-party spam filters as being a “safe sender.” The address will follow the format
[email protected], where “1” could be any number, depending on how many 920s are installed.
Of course, before the 920i can begin to function on a network, it needs to be assigned an IP address and be
configured. If this has not been done, refer to the following information.
Assigning an IP Address to the 920i
An IP address must be assigned and configured before a network connection is available. The preferred method
is to use Lantronix’s Device Installer, which is located on the Ethernet Configuration CD provided by Rice Lake
Weighing Systems (PN 72763) or downloadable from www.lantronix.com. Ensure you are using the latest
version of Device Installer and consult your company’s IT department for a recommended IP address to assign.
1. Insert the Ethernet Configuration CD and follow the Lantronix Device Installer on-screen instructions.
2. Start the Device Installer program.
