3.13.1 General ® The Burford Model 2200/2300 Twist Tyer has the ability to communicate with a terminal or a personal computer which is running a terminal emulation program. When the tyer's controller detects an unusual situation or an error, the controller sends diagnostic information to the terminal through its serial port.
Burford Corp. has developed a terminal emulation program specifically for use with the Model 2200/2300 tyers. This program is simply called TERMINAL.EXE and it provides the simplest and easiest way of communicating with the tyer's controller and capturing data to files. The program is already configured for 4800 Baud, Even Parity, 8 Data Bits and 1 Stop Bit.

Most PC's sold today include a copy of Microsoft Windows. Included with Windows is a Terminal program, which can be used to communicate with the ® Burford Model 2200/2300 tyer. This terminal program is not as easy to use with ® ® the Burford...
This is because the tyer must echo your typed commands back to the PC before they will be displayed. The tyer's controller sends some information to the serial port which is intended ® to be displayed on the optional Operator Display provided by Burford Corp. The ® Burford TERMINAL program has been written to recognize the format of these statements and display them in a box near the bottom of the screen.
A cable like the one shown below is necessary to connect between the tyer's serial port and the PC's serial port. The connection point is conveniently located at the rear ® of the tyer head and is labeled “COMM”. This cable is available from Burford Corp. Ask for Part Number 210672.
