Tyco 4100U-S1 - Manual (Page 50)

3-8
There are two jumper settings on the NIC card: 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
(default for 4100U-S1).
• 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 (default for 4100U-
S1).
• Position 2 – 3 (the left two pins): 8-bit.
All settings are labelled on the card.
P2: Tells the system which wire type is to be used.
• Positions 1 – 2, 5 – 6, and 7 – 8: 0.8mm shielded, twisted pair wiring.
• Remove all jumpers to specify 0.2mm unshielded 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 wired media
card on the right port.
