Table 3: PC/104 AT Bus Connector
Note: Two locations on the bus have mechanical keying pins to help prevent misconnection of the
PC/104 bus. These keying pins are a part of the PC/104 standard, and we strongly recommend
you leave them in place.
If you have other modules without keying pins, we suggest you modify them to include
keying.

Note: The KEY pins are to guarantee proper module installation. Pin-A1 will be removed and the
female side plugged for 5.0V I/O signals and Pin-D30 will be modified in the same manner for
3.3V I/O. It is recommended that both KEY pins (A1 and D30) be electrically connected to
GND for shielding.

PC/104-Plus PCI Bus Signals
The following table contains brief descriptions of the PC/104-Plus PCI bus signals.
Address and Data
AD[31:00] -- Address and Data are multiplexed. A bus transaction consists of an address cycle followed by one
or more data cycles.
C/BE[3:0]* -- Bus Command/Byte Enables are multiplexed. During the address cycle, the command is defined.
During the Data cycle, they define the byte enables.
PAR -- Parity is even on AD[31:00] and C/BE[3:0]* and is required.
Interface Control Pins
FRAME* -- Frame is driven by the current master to indicate the start of a transaction and will remain active
until the final data cycle.
TRDY* -- Target Ready indicates the selected devices ability to complete the current data cycle of the
transaction. Both IRDY* and TRDY* must be asserted to terminate a data cycle.
IRDY* -- Initiator Ready indicates the master's ability to complete the current data cycle of the transaction.
STOP* -- Stop indicates the current selected device is requesting the master to stop the current transaction.
DEVSEL* -- Device Select is driven by the target device when its address is decoded.
IDSEL -- Initialization Device Select is used as a chip-select during configuration.
LOCK* -- Lock indicates an operation that may require multiple transactions to complete.
Error Reporting
PERR* -- Parity Error is for reporting data parity errors.
SERR* -- System Error is for reporting address parity errors.
Arbitration (Bus Masters Only)
REQ* -- Request indicates to the arbitrator that this device desires use of the bus.
GNT* -- Grant indicates to the requesting device that access has been granted.
System
CLK -- Clock provides timing for all transactions on the PCI bus.
RST* -- Reset is used to bring PCI-specific registers to a known state.

CM17202 Fast Ethernet Controller utilityModule9 RTD Embedded Technologies, Inc.
Interrupts
INTA* -- Interrupt A is used to request Interrupts.
INTB* -- Interrupt B is used to request Interrupts only for multi-function devices.
INTC* -- Interrupt C is used to request Interrupts only for multi-function devices.
INTD* -- Interrupt D is used to request Interrupts only for multi-function devices.
Power Supplies and VIO
+5V -- +5 volt supply
+12V -- +12 volt supply
-12V -- -12 volt supply
+3.3V -- +3.3 volt supply
VIO -- This signal typically is the I/O power to the bus drivers on a PCI bus card.

RJ45 Twisted Pair Ethernet, CN4
Connector CN4 is for UTP (Unshielded Twisted Pair) wiring normally used for 10/100Base-T Ethernet. It is the
default factory installed twisted pair connector on the board.
The following table gives the pinout of CN4.

CN4 is a standard female RJ-45 connector.
Note: The RJ45 connector exceeds the height limit of the PC/104 specifications. The optional CN5
connector is also a 10/100Base-TX connection and can be factory installed if the RJ45
connector height is a problem

PCI Board Selector Rotary Switch, SW1
Since the utilityModuleuses stack through buses, the only hardware installation you will need to do is to
place the module onto the PC/104-Plus or PCI-104 stack. To do this, you will connect the PCI and/or ISA
bus connectors on the CM17202 to the respective connectors of your stack.
Before you can use this module you have to set the PCI board selector rotary switch located on the module
(SW1). If this module is the first module from the CPU module select ’0,’ if it is the second module select
’1,’ etc.

LED Indicators
The LEDs on the board are used to indicate various operations of the on-board physical layer chip. These LEDs
do not indicate any operations that may be occurring on an add-on physical layer board which is connected
through the MII connector. Listed below are the LEDs starting with the one closest to the PC/104 connector.
