Configuration 261
Server connected indicates that MVC 2050 has successfully connected
to the server. It means that MVC 2050 received the Assign TerminalID
UNIStim message, which is the last message received by MVC 2050
before a normal session is started.
Recovering: Server unreachable
The Recovering: Server unreachable message generates after MVC 2050
loses connection with the server. It indicates that the UNIStim watchdog
timer has expired and indicates loss of network connection.
Hard Reset
The Hard Reset message indicates that the server has instructed MVC
2050 to reset and clear its UNIStim-related memory. This message maps
directly to a UNIStim message.
Hardware ID
The Hardware ID screen is used to select the MAC address that MVC
2050 reports to the communication server. The MAC address can be
reset.
View the Hardware ID in the MVC 2050 Settings on the Hardware ID tab.
Hardware IDs are generated by reading MAC addresses from the PDA
Network Interface Card (NIC). When MVC 2050 is used with most server
types, the Hardware ID must be unique.
Some software, such as VPN client software, creates artificial network
interfaces with MAC addresses, which are not unique. Without a unique
MAC address, the following conflicts can occur
• MVC 2050 cannot connect to a server
•
MVC 2050 connects to the server but another device with the same
Hardware ID is disconnected from the server
• MVC 2050 disconnects from the server then automatically attempts
to reconnect
To prevent conflicts with other devices, enable Auto-Create. Auto-Create
fabricates a MAC address with a random value that is unlikely to be
repeated by another device.
Use Procedure 75 “Enabling Auto-Create” (page 262) to enable
Auto-Create.
