1 MM2/Mini4 10/100 Ethernet Daughterboard, P/N: 201750-xxx
The Prizm MM2/Mini4 10/100 Ethernet daughterboard combines the functionality of a fourport 10/100 Ethernet switch and a high speed synchronous Ethernet to serial bridge to
provide an end-to-end Ethernet link over a fiber multiplexer. This board must be stacked
onto a MM2 or a Mini4 motherboard set.
The board contains no user-modifiable jumper selections for this board. All functions are
handled automatically.
1.1 10/100 Ethernet Interface:
The 10/100 Ethernet daughterboard automatically supports both 10 and 100Mbps Ethernet
on each of the 4 switch ports. Mixed port-to-port Ethernet rates are supported and rate
adaptation is handled automatically. The 5th port on the switch connects to the synchronous
Ethernet to serial bridge chip. This chip buffers the Ethernet packets and flows the packets
serially through the MM2/Mini4 daughterboard connector at a synchronous data rated
defined by the MM2 (16Mbps) or Mini4 (25Mbps).
The 100Mbps Ethernet data rate is approximately 4 times the daughterboard throughput
capacity of the MM2 and Mini4. Therefore there will be some degradation to the Ethernet
traffic throughput over the MM2 or Mini4. At the 10Mbps Ethernet rate there should be
little throughput degradation.
Testing by Prizm has determined the following end-to-end throughput rates:
MM2 or Mini4 Ethernet Rate Throughput
MM2 10Mbps 8Mbps
MM2 100Mbps 15Mbps
Mini4 10Mbps 20Mbps
Mini4 100Mbps 25Mbps
Ethernet throughput is typically defined as the number of bits in a ping packet divided by the
round-trip time that a ping packet takes to get from the originating PC to the target PC and
back again. As this is a round-trip measurement, the ping packet bit size is doubled for this
computation.
For example from table above:
1. Size of ping packet = 15766 bytes * 8 = 126,128 bits per packet
2. Round-trip time = 17.05 milliseconds
Throughput = Size of ping packet * 2 / Round-trip time
= (126,128 * 2) / 0.01705
= 14,795,073 bps
= 14.79Mbps

1.2 MM2/Mini4 10/100 Ethernet Daughterboard Revision History:
The MM2/Mini4 10/100 Ethernet daughterboard has gone through the following printed
circuit board (PCB) and Assembly revisions:
PCB Revision A Original design.
PCB Revision B Various circuit and routing corrections.
1.3 MM2/Mini4 10/100 Ethernet Daughterboard Dash (-) Number
Definitions
The MM2/Mini4 10/100 Ethernet daughterboard has a Dash Number appended to the part
number. This Dash Number identifies the specific board configurations:
-001A // -001A PT Original configuration, obsolete
-001B // -001A PT Rev B PCB, no LED display header placed
-002B Rev B PCB, LED display header placed for Surface
1.4 MM2/Mini4 10/100 Ethernet Daughterboard Operation:
Each of the four 10/100 Ethernet ports automatically switch to follow the PC attached to the
specific port. There are two LEDs located within the quad RJ-45 connector. The left LED
(green) will be lit if the port is running at 100Mbps and will be off if 10Mbps. The right
LED (yellow) will be lit solidly if an Ethernet link is detected and blink off with traffic. All
four ports are also auto-polarity correcting so either straight or crossover cables can be used.
NOTE 1: Two DIP-socketed EEPROMs (at U15/20 and U12/13) must be placed for
this board to function correctly.
1.5 10/100 Ethernet Interface Daughterboard Indicators and
Controls:
LEDS:
There are 13 surface mount vertical LED indicators on the top of the board and 1 surface
mount LED indicators on the bottom of the board.
Top of Board
LED Indication
D1 (Green) Labeled ‘DB PWR’, Located at the upper left of the board serves as an indicator that +5VDC
is available to the board. Supply voltage to the board is selected via the placement of fuse F6
from the Daughterboard Header (J1), F7 from the Diagnostics Header (J2), or F3 from the
Auxiliary daughterboard header (J4).
D2 (Green) Labeled ‘TX DATA’, located at the center right edge of the board serves as an indicator the
diagnostics data is being transmitted out of the board on the Diagnostics Header (J4) or
Diagnostics connector (J6). NOTE: DIAGNOSTICS NOT AVAILABLE
D3 (Green) Labeled ‘RX DATA’, located at the center right edge of the board serves as an indicator the
diagnostics data is being received into the board on the Diagnostics Header (J4) or

Diagnostics connector (J6). NOTE: DIAGNOSTICS NOT AVAILABLE
D4 (Green) Located at the lower right edge of the board serves as an indicator that the microprocessor is
receiving diagnostics requests from the diagnostics PC through the Diagnostics Header (J4)
or Diagnostics connector (J6). This LED will blink ON with a received request then OFF
with the next request. NOTE: DIAGNOSTICS NOT AVAILABLE
D5 (Green) Labeled ‘Q_OF’, located on the center top edge of the board, if “OFF” provides an indication
that the Ethernet to serial chip U8 is overflowing its internal buffer. Typically this LED will
always be “ON” – not in an error state.
D6 (Green) Labeled ‘LOCAL’, located on the center top edge of the board, if “ON” provides an
indication that the programmable logic device U1 is receiving a system receive clock and
receiving data from the Daughterboard Header (J2).
D7 (Green) Labeled ‘REMOTE’, located on the center top edge of the board, if “ON” provides an
indication that the programmable logic device U1 is receiving a system transmit clock and
outputting data onto the Daughterboard Header (J2).
D9 (Green) Labeled ‘+3.3V’, located at the bottom right edge of the board serves as an indicator that the
on-board +3.3VDC power supply (U6) is working.
D10 (Green) Labeled ‘W_TX’, located on the center top edge of the board, if “ON” provides an indication
that the programmable logic device U1 is receiving data from the Ethernet to serial chip (U8)
and outputting data onto the Daughterboard Header (J2).
D11 (Green) Labeled ‘W_RX’, located on the center top edge of the board, if “ON” provides an indication
that the programmable logic device U1 is receiving data from the Daughterboard Header (J2)
and sending it to the Ethernet to serial chip (U8).
D12 (Green) Labeled “P5 LED1”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
D13 (Green) Labeled “P5 LED2”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
D14 (Green) Labeled “P5 LED3”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
Bottom of Board
LED Indication
D8 (Green) Located at the bottom left edge of the board serves as an indicator that the LED display
header is powered.
