Figure 3-11. Modular adaptors

When making modular adaptors, the 3K resistor shown in Figure 3-11

may be eliminated for use with most terminals. The resistor is used to

loop control signals back to the attached device when 4-wire cable is

used and pin 6 is not connected. When using 6-wire cable and there is

a voltage on pin 6, the resistor has no effect and the voltage on pin 6 is

passed through to the attached device.
