TRANSMIT
NOTE 1: ALL RESISTOR VALUES ARE ±1%.
NOTE 2: C1 = C2 = 0.1m.
NOTE 3: S IS A 6V TRANSIENT SUPPRESSOR.
NOTE 4: D1 TO D8 ARE SCHOTTKY DIODES.
NOTE 5: THE FUSES ARE OPTIONAL TO PREVENT AC POWER-LINE CROSSES FROM COMPROMISING THE TRANSFORMERS.
NOTE 6: THE 68mF IS USED TO KEEP THE LOCAL POWER-PLANE POTENTIAL WITHIN TOLERANCE DURING A SURGE.
