Hi
I am trying to control a set of relays using RS-232. Per the manual for the relay, I need to send ASCII codes and not ASCII characters.
Basically, I'm trying to send the equivalent of: MSComm1.Output = Chr$(254) MSComm1.Output = Chr$(47) MSComm1.Output = Chr$(29) MSComm1.Output = Chr$(8)
To me this equates to:25447298
I have no idea how to enter this via PEP.
Any help would be appreciated.

To send ASCII values as binary data, you convert to hexadecimal characters of 8 bits (a byte on this OS) and embed these characters into a string.
I am not at a computer where I can lookup the exact format PEP requires but the hex characters are as follows:
\xFE\x2F\x1D\x08
\xFE is hexadecimal for 254 \x2F is hexadecimal for 47 \x1D is hexadecimal for 29 \x08 is hexadecimal padded to 2 characters for 8
Windows Calculator in Scientific mode supports conversions to make your life easier in the future.

Hi Lyndel
Thanks for the reply! Do I need to add this to the ASCII command or can I simply enter the HEX commands directly in the HEX command box?

Enter FE 2F 1D 08 into the Hex box
or
You should also be able to enter the string I posted into the ASCII window as well.

Got it! It was a setting on the circuit board. Switch from PC to Mac control.
Life is good!
