External Serial Device Interface
You can use TPC in conjunction with the following supported card Reader options:
• External ABA Track 2 (magnetic swipe) card reader
• External 125 KHz proximity (HID) card reader
•
External 13.56 MHz contactless smart card reader (Mifare, Legic)
When the reader is attached to TPC, users wave or swipe their card to populate the fields on the Login screen. The
cards must be accurately encoded with the correct user code information. For additional information on card
encoding, refer to the "Configuring TouchPoint Consoles" chapter in the
Equitrac Professional Administration Guide
.
Serial communication between TPC and RS-232 card readers requires configuration of four parameters: Baud rate,
Data bits, parity, and the number of stop bits. Each transmitted character is packaged in a character frame that consists
of a single start bit followed by the data bits, the optional parity bit, and the stop bit or bits.
Option

Baud rate is a measure of how fast data is moving between instruments that use serial
