3 1. RS 232 (MAX 3221) Opto isolated Sub D9 male (use null modern cable for PC connection) 2 Rx In data receive, isolated from rest circuitry 3 Tx Out data transmit, isolated from rest circuitry 5 GND Supply ground potential, isolated from rest circuitry Internally connected: USART0: Rx,Tx 2. Board Supply and Control 6-way box header Pin 1 Pin Supply Supply DC supply voltage negative V 2 + Supply Supply DC supply voltage positive V 3 GND Out Ground potential from circuitry 4 ON In Closed contact to GND turns component on 5 GND Out See pin 3 6 ON In V against Supply turns component on ON and ON can be bypassed by setting the permanent on jumper (is set by default). The result is a logical or of ON, ON and the bypass jumper. 3. DC Supply 2,1mm barrel socket (use alternatively to ± supply above) V GND DIMM-CPU-CB09.odt 3 (10) Lucie Houdet, Dipl. Ing.
