Chapter 1 Product Description
Mezzanine boards
There are two types of mezzanine boards: an encoder mezzanine board and a decoder
mezzanine board. The codec board in the HD-00 K2 Media Client can host one or two
mezzanine boards of either type, so the number and type of mezzanine boards on the
codec board determines the fixed channel configuration of the HD-00 K2 Media
Client model. The encoder mezzanine board provides one record channel, while the
decoder mezzanine board provides one play channel.
Refer to “Codec board removal” on page 124 for procedures.
RTP board
This Real Time Processor (RTP) board provides a dedicated real time processor and
connections for media access and processing. It functions as a riser board, connecting
to the PCI slot below and the Codec board above.
Refer to “RTP board removal” on page 127 for procedures.
XLR board
The XLR Board provides XLR connectors at the K2 Media Client rear panel. It is
primarily an extension of the codec board to allow the space and orientation required
for XLR connections. On the SDA-00 model, the XLR connections are used for
analog audio and LTC. On other models, the XLR connections are only used for LTC.
The XLR board is connected via cable to the codec board.
Refer to “XLR board removal” on page 138 for procedures.
RS-422 adapters
RS-422 configuration varies, as follows:
• A K2 Media Client with a Type III motherboard has RS-422 adapters in rear panel
slots 1 and 7. A K2 Media Client with a Type I motherboard has RS-422 adapters
in rear panel slots 3 and 7. Each adapter is connected via an internal USB cable to
the motherboard, so while a RS-422 adapter does occupy a rear panel slot, it does
not plug into a PCI bus. Each adapter provides two RS-422 ports for connecting
equipment for remote control of the K2 Media Client.
• A K2 Media Client with a Type II motherboard has one RS-422 adapter. The
adapter is connected via PCI slot to the motherboard. The adapter includes an
external interface with eight ports. On the external interface, ports 1–4 are active.
This provides the four ports for connecting equipment for remote control of the K2
Media Client.
Refer to “RS-422 adapter removal” on page 133 for procedures.
Dual Ethernet adapter
The dual Ethernet adapter provides two Gigabit Ethernet ports. The dual Ethernet
adapter plugs into one of the standard PCI slots on the motherboard. On some models
the dual Ethernet adapter is optional.
Refer to “Dual Ethernet adapter removal” on page 136 for procedures.
