problem 1: What is the relationship between the data rate and the distance which the data can reliably travel on the EIA interface?

problem 2: What does the mechanical specifications, electrical specifications and the functional specifications of EIA-232 describe?

problem 3: According to EIA-449 standard, what is the fundamental difference between Category I pins and Category II pins?

problem 4: Draw the time domain graph for the bit pattern 10110110 as it would show on an RS-422 circuit. Suppose a 1 is 5 volts and a 0 is -5 volts. Draw the complement as well.

problem 5: By using the data in the proceeding problem, suppose that the first and last bits are corrupted by 1 volt of noise. Draw both lines and draw the difference of the complement from the signal.

problem 6: By using RS-423(unbalanced) mode, find out the data rate if the distance between DTE and DCE is 1000 feet?

problem 7: By using RS-423(balanced) mode, find out the data rate if the distance between DTE and DCE is 1000 feet?

problem 8: How much enhancement in data rate can be accomplished over 1000 feet if we move from RS-423 to RS-422?

problem 9: If 0.5 V of noise corrupts a bit on an RS-422 circuit, how many volts would be 1 required to the complementary bit?

problem 10: In which kind of a signal does bit rate equivalents the baud rate?
