The 4E Network will interface all of our PIC-based Projects to a central computer using RS485. RS485 is similar to RS232 (normal serial) except it allows multiple devices to be connected and uses twisted pairs to for balanced transmission so that much longer runs are possible. These characteristics and the ease with which it can be implemented on a microcontroller are the primary reasons why RS485 was chosen.
