Bio-Rad SmartSpec Plus Spectrophotometer - Manual (Page 14)

The serial port parameters are: 9600 baud rate, 8 data bits, no parity, 1 stop, and
XON/XOFF flow control. These parameters are pre-set in the unit. When using a serial printer
set the printer to the serial port parameters specified above. Please note that the data are sent
from the SmartSpec Plus to a computer or serial printer as hex characters. If your computer or
printer is not set to accept these characters please refer to the instrument’s instruction manual
for correct settings. (For detailed instructions see Section 4.4.)
4.4 PC Serial Connection Instructions
1. Connect RS232 9-pin serial cable from SmartSpec Plus to computer.
2. Using a terminal program (e.g. HyperTerminal), set the connection to 9600 baud, 8 bits-
no-parity-1 stop bit (9600-8-N-1), no flow control.
3. In addition to the actual data transmission/reception parameters, other parameters in
HyperTerminal may have to be set. The correct settings may vary from computer to
computer, but these are settings currently used and offered as an example. It may not be
necessary to implement all parameters. Only the Connect Direct to Com Port is essential.
