TCP Re-transmission Timeout
This feature allows the configuration of the desired TCP re-transmission timeout value. If the
ACK is not received for a packet sent from the XPort device, then the unit will retransmit the
data. The valid range is 500-4000 msec.
TCP Re-transmission Timeout (500 - 4000) (ms): (500) ?

Ethernet Connection Type
The XPort module allows for the Ethernet speed and duplex to be manually configured. Enter
0 for auto-negotiation (default). To select the speed and duplex, enter one of the following: 2
(10 megabit/half duplex), 3 (10 megabit/full duplex), 4 (100 megabit/half duplex), or 5 (100
megabit/full duplex).
Ethernet connection type: (0) ? _
Security Settings (Option 6)
Note: You can change security settings by means of Telnet or serial connections only, not on
the Web Manager. We recommend that you set security over the dedicated network or over
the serial setup to prevent eavesdropping.
CAUTION: Disabling both Telnet Setup and Port 77FE will prevent users from
accessing the setup menu from the network. Disabling Port 77FE also disables
the Web from configuring the device.
Select 6 to configure security settings.
