RS232 <=> RS422 (Add on)

One more: If you don't want to use a Max3462 a little converter-circuit would be fine: RS232-EQ GND -----#------------------------------------------------------- GND TX -----+------------------------------------------------------- RX- '------------------------------------------------------- RX+ RX ---, ,--XXXXXXX---------------------------------- TX- \| | 100 Ohm ,------------------------------- TX- |-----------# | *| | | / V | | --- | | | | '-------------'-----------' # -> connection | V -> Diode --- | Log time since I did Ascii drawings :) Gruss H. -- VCF Europa 8.0 am 28/29.April 2007 in Muenchen http://www.vcfe.org/
