Terminal settings
The PayLink-IP/232
can be configured to manage connecting to and from a terminal using a number of options, as
outlined in the following pages.
Terminal Data Format
•
7 bits even parity (default)
•
7 bits odd parity
•
7 bits no parity
•
8 bits
NOTE:
“Terminal Data Format” refers to the organization of the actual data transmitted by the terminal. The parity
settings indicated here are
not
the same as the modem parity settings.
Message Negotiation
Message negotiation settings are:
•
Send ENQ to terminal to initiate transmission
This setting should be enabled when the payment terminal expects to receive an ENQ prior to sending out trans-
action data. Possible settings are:
Default operation — “Send ENQ”, “Use SYN/SYN/SYN”, “Send ACK” all disabled (see page 15)
Opening a connection — “Send ENQ” enabled (see page 16)
Opening a connection — “Send ENQ” disabled (see page 17)
•
Use SYN/SYN/SYN preamble to establish connection
This setting should be enabled when the payment terminal looks for a synchronization string before the initial
ENQ string.
•
Send ACK to terminal after each received message
This setting should be enabled when the payment terminal expects to receive an ACK after each message
received by the server. Possible settings are:
Data flow — “Send ACK” enabled (see page 18)
Data flow — “Send ACK” disabled (see page 19)
Set InterChar delay
Inter-character delay specifies the maximum time that the PayLink-IP/232 will accumulate data before forwarding
it to its destination. Inter-character delay is a variable that can be set in the range 5-60 ms. By default the inter-
character delay is set to 20 ms.
Transaction ended by:
The PayLink-IP/232 can be configured to end a transaction with a payment terminal under a number of condi-
tions. Possible settings are:
Closing connections — “Server (default)” mode (see page 20)
Closing connections — “ACK from terminal, EOT to terminal” mode (see page 21)
Closing connections — “ACK from terminal, ACK to terminal” mode (see page 22)
Closing connections — “EOT from terminal, EOT to terminal” mode (see page 23)
Closing connections — “EOT to terminal when TCP/IP closed” mode (see page 24)
Closing connections — “ACK to terminal when TCP/IP closed” mode (see page 25)
