There are two shunt jumper ports on the NIC card that need to be set: P3 and P4.
P3: Determines the NIC data transmission rate, 57.6 kbits/second or 9600 bits/second.
Position 1 – 2 (the right two pins) or no pins jumpered: 57.6 kbits/second.
Position 2 – 3 (the left two pins): 9600 bits/second.
P4: Determines the data protocol, 8-bit or 9-bit, that the NIC card is using.
Position 1 – 2 (the right two pins) or no pins jumpered: 9-bit.
Position 2 – 3 (the left two pins): 8-bit.
All settings are labeled on the card.
P2: Tells the system which wire type is to be used.
Positions 1 – 2, 5 – 6, and 7 – 8: 18 AWG shielded, twisted pair wiring.
Remove all jumpers to specify 24 AWG twisted pair telephone cable wiring.
IMPORTANT: When using the wired media card, the Earth fault detection is
performed on the left port only. Remove R1 (1 Ohm resistor)
from the media card on the right port.
