PROGRAMMING AND INTERFACING
Reading via RS232 Interface
This is a basic example for setting the 1750 to the 20 kΩ range and taking a reading. Windows supplies
HyperTerminal as a standard accessory and may be used for executing simple RS232 functions.
Set the 1750 resistance range by sending the ASCII string, “R15X”, where “R15” is the command
for setting the resistance range and “X” is the message delimiter.
Send the ASCII character “E” to instruct the 1750 to return a value to the PC. A reading will be
returned followed by a carriage return, <CR> and a line feed, <LF>.
