The Hot Lap Computer Interface (21620) puts all information memorized by the Performance Monitor into format acceptable to the computer. All information, complete with lap and event references can be transferred to the computer. Data transfers easily over the serial cable just like a modem, using simple serial commands. The Computer Interface consists of four parts:
A Race Analyzer program on a 3-1/2 in. floppy diskette. It is in Windows and operates with any IBM PC or compatible computer.
An integrated circuit chip that installs in the 21640 Microcomputer and activates the serial connector for communication with a PC.
A 6-ft long interconnecting cable with 9-pin D connectors on both ends. This cable plugs into the Microcomputer and the serial port on the computer.
A 9-pin to 25-pin adapter for use with computers with a 25-pin D serial connector.
The Computer Interface operates on a 286 or higher IBM or compatible PC with Windows 3.1 or higher, 1MB RAM, VGA or higher graphic capabilities, and a Windows compatible mouse. It requires a hard disk drive with a minimum of 2MB available. It outputs to any windows-supported printer, including dot matrix, inkjet, laser, and Postscript printers. It requires a serial I/O card set up for COM1, COM2, COM3 or COM4. The Race Analyzer is provided on one 3.5 inch HD (1.44MB) diskette and requires a compatible disk drive.
