Motherboard Jumper Settings - Simplex 4100 Series Installation Instruction

4100/4120-6014, 4100-6078 NICs and 4100/4120-Series Media Modules Installation Instruction
Jumper settings
The NIC card, along with the fiber, modem, and wired media cards, all have jumpers that must be set.

Motherboard jumper settings

NIC-compatible jumper settings on CPU motherboards depend on which motherboards are used.
Motherboard 565-274:
• JW1 and JW2 must be installed.
• Jumper plugs P5-P8 must not be installed.
Motherboard 566-227:
P10: Port 1 settings.
P11: Port 2 settings.
• P10/P11 position 1 - 2: Network card (NIC) attached to the CPU motherboard (default).
• P10/P11 position 2 - 3: RS-232/2120 card attached to the CPU motherboard.
Motherboard 566-938:
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 address setting
Use SW2 to set the NIC card address.
NIC jumper settings
Set two shunt jumper ports 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.
• 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 to use.
• 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.
P3 and P4: Use to improve shorted line sensing with shorter communications lines.
• Present on Rev C (and later) of the Media Module (565-413).
• For 18 ga communications lines of 5 kft or less, or 24 ga communications lines of 2 kft or less, install P3 and P4 jumpers in position 2-3.
• For longer lines, install jumpers in position 1-2.
Important: When using the wired media card, the earth fault detection is performed on the left port only. Cut and remove R1 from the media card on
the right port.
Modem Media Card jumper settings
Non-4100U/4100ES only. P4 and P5 on the modem media card tell the system how the card is used.
P4: Sets the card up as a network media card or a standalone modem.
• Position 1 - 2 (required): Sets the card up as a network media card, a service modem, or a physical bridge.
• Position 2 - 3: Sets the card up as a stand-alone modem.
P5: Specifies which connector is used for data transmission.
• Position 1 - 2: Use for modem media board or stand-alone modem. It specifies that the transmission data comes from the 40-pin connector
(J1).
• Position 2 - 3: Use for service modem or physical bridge. Specifies that the transmission data comes from the 10-pin RS-232 connector (P1).
