SIIG manual Providing Power for EVTEK-5103, http//pdfserv.maxim-ic.com/arpdf/DS89C420.pdf

Providing Power for EVTEK-5103:					1) If the main power input is used, connect the MASCOT 8717 plug
					2) If the auxiliary power input is used, connect a standard 9 V battery
Choosing EVTEK-5103 Operation Modes:
		Switch Position:			Mode	Corresponding Operation Mode:	Terminal
	MSB (*		mid (*	LSB (*	nr.		Response:

(* when seen from the front, MSB switch is the rightmost, and LSB is the leftmost

Implementing Serial Connection:

Connect the EVTEK-5103 Board’s serial port 1 and PC’s available serial port with a cross-connected serial cable

Interfacing the EVTEK-5103 from a PC:

It is recommended to use the “EVTEK-5103 Interface” application, that is specifically made for this purpose. The user guide for the application: START MENU Æ PROGRAMS Æ EVTEK-5103 Æ INTERFACE MANUAL

If using a terminal program instead of “EVTEK-5103 Interface” application:

Use Hyperterminal (not under Windows 2000), or Tera Term http://hp.vector.co.jp/authors/VA002416/teraterm.html

Terminal Program Connection parameters:

	Baud rate = 57600 kbps				Data bits = 8	Flow control = none
	Parity = none				Stop bits = 1	COM port = the one you’re using on PC
	Enter key = CR+LF				Local echo = no	Destructive backspace = yes
	Also, set terminal scrollback buffer to				at least 500 lines for convenience of use.
