The 907-1394 media converter card supports multiplexing and de-multiplexing of up to two IEEE-1394-type
data streams. This card supports devices capable of transfer modes S100 (100 Mbps), S200 (200 Mbps), or
S400 (400 Mbps).
External 5 VDC (±10%) power is required via Molex connector labeled J1. The board itself draws up to 0.6 A
of current. When stacked on a motherboard, the card can also be powered via the PC/104 backplane. The
907-1394 media converter can also be configured (configuration includes populating the optional DC-DC
converter) to acquire power from devices connected to the IEEE-1394 bus. The input voltage must be
between 10 and 28 VDC, and the connected devices must meet the IEEE-1394 specification. Alternately, the
board can provide power to external devices, supplying up to 500 mA per port. The card uses a 3 A time
delay fuse for the input power (includes budget for sourced power to external devices), and another 1 A fuse
for board circuitry. Appropriate replacement fuse part-numbers are provided in the Appendix A.
As shown in Figure 4-3, the 907-1394 card has LEDs for Power, Board Reset, Cable-Link, and Optical Signal
Detect. The Power LED is on when the board is powered, the Board Reset LED is on momentarily during
power up and continuously for an under-voltage input. The Cable-Link LED is on when any link has been
established on either the IEEE-1394 or optical interfaces. The Optical Signal Detect LED is on while sufficient
optical power is detected at the optical receiver, but does not necessarily indicate valid frame data.
The 907-1394 card can be assembled to support various optical configurations including 1310 nm or 1550 nm
bidirectional transceivers using two fibers, or 1330/1550 nm transceivers coupled with a WDM to multiplex all
of the data onto a single fiber. The access fiber bushing near the middle of the card is typically an ST/PC
connector, but FC/PC is also available.
