CONNECTING THE UNIT TO A PC FOR PROGRAMMING
In order to program the unit, the unit and a PC (IBM-compatible personal computer) must
communicate via an asynchronous RS232 serial link.
The adaptors shown in the Appendix 1 on page 25 provide this link. A simple adaptor for
the SX450GA like that shown in Figure 10 can be purchased from Wood & Douglas,
product code 01106 1503 A.
If your computer does not have an RS232 serial port, then a USB-to-serial adaptor is
required, described in Appendix 2 on page 27.
The SX450G and adaptor also require a power supply capable of sourcing approximately
60mA.
