Terminal ConfiguraTion

8. CommuniCaTion proToCol- This option selects the communication protocol and your processors
requirement that the terminal will be using (dial-up, TCP/IP, wireless, etc).
D Press <8> repeatedly to cycle through the available selections. Stop on the communication protocol
that meets your requirements.
9. CommuniCaTion message formaT- This option species 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.
D Press <9> repeatedly to cycle through the available options. Stop on the comunication message
format that meets your requirements.
0. nua numBer (neTwork user address) / hosT response TimeouT- The NUA number is equivalent
to a telephone number for PakNet/SwiftNet radio networks.
For TCP/IP comunications, the Host Response Timeout indicates how long to wait for a response from
the host before timing out and canceling the transaction.
D If this number/time is required, press <0> on the keypad. Enter the NUA number or the Host
response time (in seconds) in the data entry dialog box. Press <enTer> when completed.
f1. enaBle persisTenT reversals- When the terminal sends a customer transaction request to
the processor, the transaction is performed and a conrmation is sent back to the terminal. If the
conrmation is not received, for whatever reason, the intergrity of the transaction is in question. The
terminal will not conrm 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. Option <F2>, “Reversal Attempts”, will be activated to enter
this number.
D Press <F1> to toggle between enabled (checked) or disabled (unchecked).
*F2* Press <F2> and enter the number of reversal attempts in the data entry dialog box. Press <enTer>
when complete.
NOTE: A zero (0) represents “innite”. If this is entered, the terminal will continue the reversal
attempt indenitely.
f3. enaBle reversals for proToCol errors- 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.
D Press <F3> to toggle between enabled (checked) or disabled (unchecked). Press <enTer> when
complete.
