Pin Serial
What is the maximum amprage for a serial 9-pin connectors (16550-compatible)?
The normal maximum for a 9 pin 'D' type sub miniature connector is 1 amp per contact, however the typical serial I/O chip is only designed to deliver 50mA per output pin.
The Maximum out voltage for RS232c is + 12v & -12v, although normally there is a 'dead' area between +3v ab -3v to absorb noise on the lines, some higher quality devices will work with a dead area as low as +1v & -1v.
