Dear all
Sorry if this has been covered before, I could not find an
exact example matching my need, and format converts are still a
bit hard for me. 

I am trying to write a StreamDevice IOC for a display. 

The format needed by the display is
cmd(MSB) cmd(LSB) charater(MSB) charater(LSB)
Where values are in hex representation 

exampel for a simpel write command (
cmd(MSB)
cmd(LSB) = FF FE)

FF FE 00 39
which will send the charater "9" ascii 0x39 to the display

Is there a simple way to generate such string representations
of numbers from a PV (potentially including scientific
representation). 

Best
