Chapter 4 Networking
Step 1. Configuring Network Cards
Overview
The NIC card, along with the each media card, all have jumpers that must be set as shown below.
Motherboard
Jumper Settings
NIC-compatible jumper settings on CPU motherboards depend on which motherboards are used.
Motherboard 565-274 (Figure 4-2):
• JW1 and JW2 must be installed.
• Jumper plugs P5-P8 must not be installed.
Motherboard 566-227 (Figure 4-2):
P6: Port 1 settings.
P5: Port 2 settings.
• P6/P5 position 1 – 2: Network card (NIC) attached to CPU motherboard (default).
• P6/P5 position 2 – 3: RS-232/2120 card attached to CPU motherboard.
RUI+ Master Motherboard 566-938 (for figure see Chapter 2):
P10: Port 1 settings.
P11: Port 2 settings.
• P10/P11 position 1 – 2: Network card (NIC) attached to CPU motherboard (default).
• P10/P11 position 2 – 3: RS-232/2120 card attached to CPU motherboard.
NIC Card Address
Setting
Use SW2 to set the NIC card address. Refer to Appendix A for the address table.
NIC Card Jumper
Settings
There are two shunt jumper ports on the NIC card that need to be set: P3 and P4. (Figure 4-1)
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.
Wired Media Card
Jumper Settings
P2: Tells the system which wire type is to be used. (Figure 4-5)
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.
