Installation and Setup
WebRelay-10 Users Manual
Mode
This option allows the Ethernet port to be set to
Half Duplex
or
Full Duplex
. Legacy Ethernet
operates in
Half Duplex
mode which means that devices can either send data or receive data, but
not both at the same time.
Full Duplex
means that devices can send and receive data at the same
time. The default setting for this field is
Half Duplex
.
Mail Server (SMTP)
The name of the SMTP (Simple Mail Transfer Protocol) mail server (for example mail.example.com)
or the IP address of the mail server (for example 192.10.10.10) should be entered in this field. There
is no default setting for this field.
Note: If the server name is entered and not the IP address, the address of a DNS server will be
required.
Mail Server Port
This field is used to specify the SMTP Mail Server Port. The default setting is 25, which is the
standard SMTP port.
User Name (If Required)
If the SMTP mail server requires authentication, the user name must be entered here. There is no
default setting for this field.
Password (If Required)
If the SMTP mail server requires authentication, the password must be entered here. There is no
default setting for this field.
Return Email
WebRelay-10 will not receive email messages, but when WebRelay-10 sends email messages, it
must include a return email address. This field is used to specify the return email address. Note that
although WebRelay-10 will send email messages with any email address specified in this field,
some email filters (spam filters) will not allow messages through that include an invalid email
address. There is no default setting for this field.
Email 1 to Email 5
Enter the email addresses of up to five recipients for alarm messages in these fields. There are no
default settings for these fields.
Email Length
Choose either “full” or “short” email lengths. When “full” is selected, all visible fields in the control
page will be included in the email message to be sent out; however if “short” is selected, the email
content will only be a brief description of what triggered the email message.
Remote Reboot
To cause the device to reboot, the following command can be entered into the address bar of the
browser:
http://192.168.1.2/networkSetup.srv?rbt=1
The username and password will be requested
before the reboot will occur, so that only administrators of the device can cause the reboot.
MTU Setting
To change the MTU, manually enter the advSetup.html (case sensitive) page into the address bar.
(
http://192.168.1.2/advSetup.html
). This new setup page will have a text box that will allow the MTU
to be changed. The valid range is 256 to 1476 bytes. MTU is a network parameter that stands for
Maximum Transmission Unit. This defines the max size, in bytes, of the TCP packets sent out from
the device. This normally can be left alone, but there are some circumstances where it might be
beneficial to change it. One of these circumstances is when the device is to be used over a VPN
(virtual private network). VPN's add extra information to TCP packets, if the new packets are too big
to physically travel across the network (greater than about 1500 bytes) then the packets will be split
up. This causes problems for some firewalls and those firewalls will just discard the packets. To fix
this, the MTU can be adjusted until the TCP packets do not get split up.
