all need way of connecting serial (rs-232) signal chip.
most people use cheap usb->ttl rs-232 dongle (about $2.50 on ebay). other option rs-232 ttl converter, consists of db9 connector, max232 chip, , capacitors.
do not connect chip directly rs-232 port on computer. ports can generate +/- 12v blow chip.
