[. . . ] PayLink-IP/Dial Configuration Guide This document describes the configuration features of the PayLink-IP/Dial. Hardware connection On-line connection Network settings Advanced network settings Terminal side configuration Host side configuration Protocol configuration Password configuration Glossary Appendix A: Message negotiation Appendix B: Hardware status LEDs 1. Connect the power supply to the PayLink-IP/Dial and to AC power. The power (red) LED will light to indicate that the unit is receiving power. [. . . ] When the message format requires a Terminal ID, enter it here. This field supports a maximum of 20 characters. Terminal settings The PayLink-IP/Dial 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. The modem will negotiate baud rate downward until it can connect to the terminal. · · · · · · · · 14400 V. 32 bis (SDLC) 12000 V. 32 bis (SDLC) 9600 V. 32/V. 32 bis (with Trellis coding) (SDLC) 9600 V. 32 (no Trellis coding) (SDLC) 7200 V. 32 (SDLC) 4800 V. 32/V 32. bis (SDLC) 2400 V. 22 bis (SDLC) 1200 V. 22/V. 22 bis (SDLC) NOTE: If possible, choose a mode that will minimize negotiation of baud rate between the payment terminal's modem and the PayLink-IP/Dial. Doing so may reduce the total time required to process transactions. If the PayLink-IP/Dial's baud rate is set higher than the baud rate at which the terminal will communicate, unnecessary steps in baud rate negotiation will occur. Terminal ID When the message format requires a Terminal ID, enter it here. This field supports a maximum of 20 characters. A08 PayLink-IP/Dial Configuration Guide Page 10 of 29 Set InterChar delay Inter-character delay specifies the maximum time that the PayLink-IP/Dial 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. Rev. A08 PayLink-IP/Dial Configuration Guide Page 11 of 29 7. Protocol configuration If you choose any of the "Protocol Configuration" buttons from the Host Side Configuration page, a Protocol Configuration screen will appear. Each payment host set up on the Host Side Configuration page can be assigned its own protocol settings. If the terminal is configured for asynchronous communications, the Protocol Configuration screen will take the following form: Figure 8: Protocol configuration (Asynchronous) If the terminal is configured for SDLC communications, the Protocol Configuration screen will take the following form: Rev. A08 PayLink-IP/Dial Configuration Guide Page 12 of 29 Figure 9: Protocol configuration (SDLC) These pages present the protocol configuration settings for the any of the PayLink-IP/Dial's payment hosts. The following can be configured: Server Data Format (Async only) This setting allows configuration PayLink-IP/Dial to match the data format of the server to which data is sent. Settings are: · · · · 7 bits even parity (default) 7 bits odd parity 7 bits no parity 8 bits Message formats (Async only) A selection of message formats are available for communicating with the remote server. The choice of format will depend on the requirements at the remote server. [. . . ] Figure 18: Opening a connection -- "Send ENQ" enabled Rev.

A08 PayLink-IP/Dial Configuration Guide Page 20 of 29 Send ACK to terminal after each received message This setting should be enabled in two general situations: · where the payment terminal expects an ACK string to follow the transmission of data, and the payment processing server does not send that string or, · where delays in transmission time would lead to the payment processing server's ACK string being received late by the terminal, causing the terminal to time out.
