Card P/N
Config. Dwg.
Diagnostics:
Top and side views of the 907-HDM2-R card are shown Figure 3-16. The backplane PC/104 connector allows
stacking of other 907 cards. The 907-HDM2 card receives +5 VDC power through a standard two-pin Molex
power connector. The power input has overvoltage and reverse polarity protection. The 907-HDM2 card can
also receive power via the PC/104 connector from other cards when used in a Model 907 stack. Typical
current draw is 1.5 A from a +5 VDC power supply.
At the 907-HDM2-R (remote end), the HD signal is input at 75-ohm Mini-SMB jacks J7/J8, as shown in
Figure 3-16. Note that mating connectors and cables must be 75 ohm impedance. Typically, for a single
camera application, J7 (channel 1) is used for the input. The input HD video signals are streamed to the
output video connectors of the 907-HDM2-C.
The serial data ports (connector J2 and J6) of the 907-HDM2 multiplexer motherboard card can be configured
as RS-232 or RS-485 using switch SW1 (channels are default configured as RS-232). Please refer to
configuration drawing 907-2052-00 for more information.
The 907-HDM2 has an array of diagnostic LEDs for Power, No Link, Link Ready, Video, and Serial Data I/O
Activity for each on-board data channel. The power LED is green when the input power voltage is within an
acceptable range. When the SFP transceiver is receiving sufficient optical power, the Link Ready LED is
green; otherwise, the No Link LED is red. The Video LED is green when valid HD video is being detected.
Serial data activity LEDs are on when channels are in the "space" state, i.e. not idle.
The optical configuration of the card, and any other special options, are designated by the –XX suffix of the
part number. Refer to the configuration drawing for more details.
