Using the utilityModule is straightforward, and essentially identical to any other Ethernet card.
When CM312 module is powered on, data in the EEPROM on board is transferred to Ethernet
controller’s internal configuration registers. The data in the EEPROM contains information
configuration such as the base address of the card, the active interrupt line on the PC/104 bus for
Ethernet access, the media type in use, etc. The factory default setting of the board is at I/O
address 0x320 and IRQ 5. And if there is a resource conflicting, you need to change your setting
on CM312 with the other I/O boards removed temporally by executing CM312SET program as
described in the later chapter.

Diagnostic LEDs
If CN8, the RJ45 connector, has two LEDs that are used to indicate status and provide some
diagnostic information in case of malfunctions.

COL LED
The LED is normally off, and flashes when the module detects a collision on the network.
Collisions may be due to low-quality cable, which allows crosstalk between the transmit and
receive pairs, miswiring, or a malfunctioning device on the network.
LNK LED
The LED is turned on when a valid 10Base-T link is detected by the chipset. It is only active when
using the 10Base-T UTP connection with link integrity checking enabled. If it is off, the UTP
wiring may be broken or incorrect, link integrity checking may be disabled, or you may be using
the 10Base-2 or AUI interface.
Boot ROM Socket
In some applications, you may wish to use the boot ROM socket of the utilityModule to boot a
connected cpuModule from a remote server.
The socket will accomodate a 32 pin PLCC EPROM or Flash memory devices of size 8k, 16k,
32k, or 64k bytes. The device must be a byte-wide architecture.
The boot ROM feature can be enabled using the CM312SET program described on page 28.
