3.4 907-HDM2 Multiplexer Motherboard

The 907-HDM2 multiplexer motherboards support up to two HD-SDI channels, 4 bidirectional serial data
channels that are switch configured for either RS-232 or RS-485 and up to six expansion cards via the
PC/104 data ports. The four on-board serial channels are always available and are not disabled by adding
expansion cards. RS-422 is only available as a factory modification. This card is compatible with SMPTE-292
signals on coaxial cable, which includes 720p, 1080i and 1080p formats.
The 907-HDM2 motherboard uses a small form-factor pluggable (SFP) optical transceiver for quick and
reliable configuration of optics and an array of board-edge LEDs for diagnostic purposes. The SFP
transceiver used in this card supports high optical data rates of up to 3.125 Gbaud. Typically optical budgets
are 20 dB or greater. In higher budget systems a minimum of 5 dB attenuation is recommended for bench
testing to ensure receivers are not saturated. The 907-HDM2 is recommended for singlemode operation only.
Please refer to configuration drawing 907-2052-00 for more information.
