PMAC2A PC104 Hardware Reference Manual

If this socketed resistor is configured as a pull-up resistor (by reversing the SIP pack in the socket), the two parallel 2.2 kresistors act as a single 1.1 kpull-up resistor, holding the line at +5V in the absence of an external signal. This configuration is required if complementary open-collector drivers are used; it is permissible for differential line-driver inputs.

If Pin 1 of the resistor pack, marked by a dot on the pack, matches Pin 1 of the socket, labeled by a white square, then the pack is configured as a bank of pull-down resistors. If the pack is reversed in the socket, it is configured as a bank of pull-up resistors.

The following table lists the pull-up/pull-down resistor pack for each input device:
