RS-485 parameters
Using basic programs, such as the Hilgraeve HyperTerminal (included in most Microsoft
Windows software packages), the Turbimax can provide basic communication functions.
You could also use Visual Basic or other programs. The standard communication
parameters are: 8 bits, no parity and 1 stop bit. You can modify these parameters using the
following menus. They will appear only if RS-485 was selected as the output (→  19).

Sample communication
The master computer requests a report from the Turbimax.
• To this end, the master transmits the following to the Turbimax:
– Byte #1 the initial character ":" in ASCII or "3A" Hex
– Byte #2 the address of the Turbimax being queried
– Byte #3, 4 "CR LF" in ASCII or "0D 0A" in Hex
• The Turbimax responds with:
– The same initial character ":" in ASCII or "3A" Hex
– Its address
– The display value for the turbidity content
– The unit
Communication would proceed as follows:
‣
The master computer requests a report from address 1: : 1 CRLF
 The Turbimax, which is located at address 1, responds with: : 001 0.0249 NTU
Desiccant alarm
If the humidity detector in the Turbimax indicates that the humidity of the internal
environment may lead to condensation, the device outputs the warning DESC. If desired,
the desiccant warning can activate the alarms and send 2 mA to the current output.
