SkanWasher 300 User Guide A-1
Appendix A: Serial Communication Option (RS-232)
The SkanWasher 300 is a stand-alone microplate washer but with the Serial
Communication Interface option, it can be controlled by another computer.
An additional kit is required to complete this option. Order catalog number
0200-3966 for RS-232 kit. The protocol for this communication is designed as
a one-character command/reply protocol. The standard protocol contains the
following communications: start, stop,and program selection.
The RS-232 connection on the SkanWasher 300 is a 5-pin connector that is
exchanged for the 3-pin connector used to connect the waste level alarm. The
connector is then used for both the waste reservoir alarm and serial interface.
Both cables can be connected at the same time. The host computer connector
is a female 9-pin D-SUB that can be connected directly to a serial port on a
PC.
