5-2. UTP Cable / RJ-45 Jack Definition
Straight through twisted pair cable is typically used to connect a hub to a server or workstation.
In a straight through connection, Pin 1 at the server, Pin 2 at the hub connects to Pin 2 at the
server, and so on. Figure A-1 shows the locations of pins on a standard RJ-45 plug on a
twisted-pair cable.
Table A-1 shows the wiring in a straight-through twisted-pair cable (Pins 4, 5, 7 and 8 are not
used).

5-3. Connecting 100Base-TX Fast Ethernet Network
To connect the adapter to 100Base-TX Fast Ethernet Network, you need a twisted-pair
Category 5 cable with RJ-45 modular jacks at both ends. This cable can have a maximum
length of 300 feet (100 meters).
5-4. Remote BOOT ROM function
This function is available with the BIOS programming for indicated operation system. The
remote boot function allows the computer to boot up over the network, instead of using the
local operating system device. This enables the system to be a diskless workstation
environment.
5-5. Diagnostic Program (RSET8139)
This program allows you to verify the configuration and isolation of faults.
Program (RESET8139.exe) provides the following function:
•
Displays the current configuration of the adapter
•
Performs network diagnostic tests to verify the operation of the adapter’s basic
functions, and the adapter’s ability to communicate over the network with another
adapter.
•
Provides set up for new configuration to make a change specify settings: Remote
BOOT ROM, Flow Control and Full-Duplex mode Enable/or Disable
Full duplex operation is set automatically if the Full-duplex option is set to Disable. Please
follow the prompt instructions to set-up or change the system configuration.
Note:
Before running the setup program, make sure the adapter’s driver is not loaded,
otherwise unpredictable results may arise!
The program can be set the on board configuration to provide diagnostic testing. It is for
testing the basic function verification, EEPROM data Access, loop back operation, and the
ability to communicate over the network with another adapter.
