PT200MI instruction manual 35
From the RS485 port, input a command “<ENQ>IDXX<CR><LF>”, indicator responds
“<ACK>XX<CR><LF>”, then input a command “SET<CR><LF>”, the display will show “SET”. XX is
the indicator ID set in function F14 above.
The sequence of set-point setting via serial port involves sending a series of parameters followed by
<CR><LF> and receiving a subsequent response from the PT200MI. If an invalid parameter is sent
the PT200MI responds NO? <CR><LF> and a correct entry must be made. When the correct
parameter has been sent the PT200MI send N<CR><LF> to move to the next stage.
Note that commands are case sensitive.
Note that the factory setting for INPUT1 is FUNC and INPUT1 must be connected to COM to
enter the setting mode.
Note: The set-point value is entered as a number without decimal point and must be a multiple
of the indicator step size. i.e. if the indicator maximum capacity is 100.00 and the step is 0.05
and the set-point load is 75.15 enter 7515 for num.
