Dial Backup for Ethernet Communication

When Ethernet communication is not available, the base to which the terminal is registered will attempt to use dial communication as backup. After a transaction is performed on a terminal/base using dial as backup, the base will attempt to use Ethernet communication for the next transaction.

Note:  When dial backup is used, the terminals (if more than one is registered to a single base) cannot share the dial line. Only one terminal can process a transaction at a time and each transaction must be completed before the next transaction can be attempted.

To allow the communications base to use dial backup, a dial cable must be connected to the communications base, and the appropriate dial parameters (e.g., the dial prefix) may have to be configured.

When the base uses dial backup, the message ETHERNET COMMS ERROR-DIAL USED PRESS OK appears on the terminal. Press the green key to acknowledge the message and return to the READY screen. The base will revert to Ethernet communication for the next transaction.
