Support Video Inputs
Audio-In
Each channel on the encoder can accept digital audio via the HDMI port (
Digital L+R 1/2
) or
analog audio using the A/V breakout cable (
Unbalanced
). The HDMI port (High Definition
Multimedia Interface) carries high-quality multichannel audio. It moves the audio across the
TMDS lanes using a packet structure. The audio can be sampled at rates of 32, 44.1, or 48
KHz.

Supported Digital Audio Formats
COM 1/COM 2
RS-232/422/485 COM Port Pinouts
The encoder has two COM ports. COM 1 is generally used for management (9600 8N1)
although it can also be used for passthrough; COM 2 is used for passthrough. When COM1
Passthrough is enabled, the management port and CLI are not available. The COM
Passthrough Port is used to pass control information between VBrick appliances over the
network. The
COM
port presents a standard DTE interface on an RJ-45 connector. The serial
port operates at a default rate of 9.6 Kbps, Async, 8-Bit, No Parity, Controls = None. The
pins on the passthrough port can be set for RS-232
or
RS-422-485 (see below) using the
COM
Interface Type
parameter on the Passthrough page in VBAdmin.
†
Each Blade or Appliance can be populated with one or two AVMs.
†† XPS = Extended Performance System: encodes at standard resolutions only.
††† HPS = High Performance System: encodes at standard and high definition resolutions.

Description
Component The component connectors (
YPbPr
) on the A/V cable support high
definition video and audio.
