Serial port activity is indicated by two status LEDs as described in “Appendix B: Hardware status LEDs” on page 26. Cabling The PayLink-IP/232 looks exactly like the COM port of a PC from the point of view of the payment terminal, and should be hooked up in precisely the same fashion. -

By default, the PayLink-IP/232 ships with no pass- word. - Page 4 From the Configuration Menu you can open screens to view and modify network settings, payment terminal interface settings, host side interface settings, and passwords for the PayLink-IP/232. The radio buttons displayed on this screen indicate the current configuration of the PayLink-IP/232; changing these settings is done by clicking therelevant “Con- figure”...

IP address The IP address for the PayLink-IP/232 will identify the device on the LAN on which it is located. Any conventional IP address can be used. The PayLink-IP/232 ships with its default IP address as 192.168.0.35; ensure that this IP address is accessible on the LAN onto which the PayLink-IP/232 is being installed. - Page 6 If installing the PayLink-IP/232 onto a network where IP addresses are to be assigned by a DHCP server, the “DHCP enabled” checkbox must be set. The PayLink-IP/232 will act as a DHCP client and obtain its IP address from the DHCP server/s on its LAN.

Use this dialog box to change the TCP port number assigned to the PayLink-IP/232. By default the PayLink-IP/232 assigns TCP port 2300 to the PayLink-IP/232; if another device on the network is already using this TCP port number, reassign the PayLink-IP/232 to another TCP port. -

In addition to the parameters above, a “fallback” IP address and IP port can be supplied for each of the payment hosts configured. In the event that the PayLink-IP/232 cannot connect to the primary address for the host, the fallback address will be attempted. -
Page 11: Protocol Configuration
These pages present the protocol configuration settings for the any of the PayLink-IP/232’s payment hosts. The follow- ing can be configured: Server Data Format This setting allows configuration PayLink-IP/232 to match the data format of the server to which data is sent. Settings are: •... - Page 12 Data is sent as raw packets with a user-defined 4-byte header. Each byte is entered as a two-character hexadeci- mal value. The default header setting is 00 00 00 00. Data is passed through the PayLink-IP/232 to the server with- out framing or parsing.
- Page 13 Figure 13: First Data framing Send message as: This dialog specifies encryption options for server connection used by the PayLink-IP/232. By default SSL is enabled. Options are: • SSL 3.0 encrypted data (default) • Data Only - SSL off (no encryption) NOTE: SSL must be enabled for secure payment processing.

To unlock the PayLink-IP/232, it must be given the “unlock password.” To do so, direct a web browser to the address “xxx.xxx.xxx.xxx/unlock.htm” , where “xxx.xxx.xxx.xxx” is the IP address of the unit. At this point the “unlock password”... - Page 15 STX. Start of TeXt character (HEX 02). A flow control character used to delimit the start of a data block or frame. SYN. SYNchronize character.

Page 16: Appendix A: Message Negotiation
By default, the three settings covered under this topic (“Send ENQ to terminal to initiate transmission” , “Use SYN/ SYN/SYN preamble to establish connection” , and “Send ACK to terminal after each received message”) are dis- abled. This means that by default the PayLink-IP/232 operates transparently, passing all negotiation messages directly between the terminal and the payment server. - Page 17 (possibly resulting from SSL negotiation) would lead to the payment pro- cessing server’s ENQ string being received late by the terminal, causing the terminal to time out.

- Page 22 Transaction ended by ACK from terminal, EOT to terminal: In “ACK from terminal, EOT to terminal” mode, the PayLink-IP/232 receives an ACK character from the terminal and responds to the terminal with an EOT character. This shutdown mode is typically used when the terminal requires an EOT to close the connection, but the server is not programmed to send an EOT.
- Page 23 Transaction ended by ACK from terminal, ACK to terminal: In “ACK from terminal, ACK to terminal” mode, the PayLink-IP/232 receives an ACK character from the terminal and responds to the terminal with an ACK character. This setting is used for terminals that end connections after receiving an ACK rather than an EOT (usually supplied by a server).
- Page 24 Transaction ended by EOT from terminal, EOT to terminal: In “EOT from terminal, EOT to terminal” mode, the PayLink-IP/232 receives an EOT character from the terminal and responds to the terminal with an EOT character. This shutdown mode is typically used when you want the termi- nal to close the connection (as when the terminal is performing a batch operation).
- Page 25 Transaction ended by EOT to terminal when TCP/IP closed: In “EOT to terminal when TCP/IP closed” mode, the PayLink-IP/232 sends an EOT character to the terminal if the TCP/IP connection is closed by the server. Figure 24: Closing connections — “EOT to terminal when TCP/IP closed” mode Rev.
- Page 26 Transaction ended by ACK to terminal when TCP/IP closed: In “ACK to terminal when TCP/IP closed” mode, the PayLink-IP/232 sends an ACK character to the terminal if the TCP/IP connection is closed by the server.
