When enabled, the Predial option sets the terminal to dial the processor and establish a connection as the card is inserted into the card reader. This provides quicker processing of customer transactions.

When required, this option must be enabled (checked). Option 5 will then be activated. Correct header data must be entered in the data entry dialog box.

CAUTION: Enabling the Communication Header when contacting a processor that does not require this feature WILL prevent any type of transaction from completing. If the Communication Header is required, disabling this feature or having incorrect data in the data field WILL also prevent transactions from processing.

Rule of thumb: If the Communication Header IS required, enable (check) and enter the header data.

If the Communication header is NOT required, disable (uncheck).

By default, the length of terminal sequence numbers is restricted to four (4) bytes of data. However, some processors require extended length terminal sequence numbers to be correctly represented.

Press 6 to toggle between enabled (checked) or disabled (unchecked).

Press ENTER when completed.

This option selects the communication protocol and your processor's requirement that the terminal will be using.

Press 8 repeatedly to cycle though the available selections. Stop on the communication protocol that meets your requirements.

Options include:

• TDL (Triton Dynamic Language - for dial-up)

• TDL w/o EOT

• TCP/IP

• TCP/IP (wireless)

• VSAT

• Cardway

• Radiopad (8-N-1)

• Radiopad (7-E-1 Emulation)

This option specifies the content and structure (format) of messages that pass between the terminal and the host processor during transactions. This setting will depend on your host processor/networks communication requirements.

Press 9 repeatedly to cycle through the available options. Stop on the communication message format that meets your requirements.

NUA Number (Network User Address) The NUA number is equivalent to a telephone number for PakNet/SwiftNet radio networks.

If this number is required, press 0.

Enter the NUA number in the data entry dialog box.

Press ENTER when completed.

When the terminal sends a customer transaction request to the processor, the transaction is performed and a confirmation is sent back to the terminal. If the confirmation is not received, for whatever reason, the integrity of the transaction is in question. The terminal will not confirm the transaction or dispense currency, but will instead attempt to restore the customer's account to pre-transaction condition, essentially reversing the transaction.

By default, the terminal attempts one (1) reversal attempt. If there is a degraded communication path or dispenser malfunction, more than one attempt may be necessary. By enabling this feature (checked), you can set the number of reversal attempts.

A zero (0) represents infinite. If this is entered, the terminal will continue the reversal attempt indefinitely!

Conditions may warrant reversals for other instances of communication failure. In particular, the need to ensure accurate communication of protocol commands and status messages that are not necessarily related to customer transactions may also necessitate use of reversals. This option (when enabled) can be used to reverse the consequences of compromised communication.
