Terminating Resistor Configurations | Compaq 5532, 5531, 5525B

Chapter	5	IEEE 1284 Parallel Interface

Host Logic High—Driven by the host. When set to high, the host indicates all of its signals are in a valid state. When set to low, the host indicates its power is off or its signals are in an invalid state.

nInit —Resets init interface from the host.

Terminating Resistor Configurations

The factory equips the printer with several resistors that are used for parallel interface configurations and are suitable for most applications. These 470 ohm pull-up and 1K ohm pull-down terminating resistors are located at RP1 and RP2, shown in Figure 13.

If the values of these terminating resistors are not compatible with the particular interface driver requirements of your host computer, you may need to install resistors with different pull-up and pull-down values.

RP1 Default: 470 ohm
	Alt 1: 220 ohm
	Alt 2: 1K ohm
RP2	Default: 1K ohm
	Alt 1: 330 ohm
	Alt 2: none
