Supported Audio Formats

The S1801e, S1802e, S1808e-A, S1816e-A, S1801e-R and S1801e-R-HD

supports bi-directional audio: audio input and output. Audio input allows you to

capture audio signals from a camera, provided that it supports audio, at the

same time it captures video.

Currently, the S1800e series devices support the following audio formats:

Codec

Sampling

Frequency

Bits per Sample Bitrate

PCM (no

compression)

8 kHz 16 bits/data 28 kbits/sec

(8kHz)

G.711/μ-Law (8

bits)

8 kHz 14 bits

signed/data

64 kbits/sec

Note

The S1816e-SR and S1816e-SR do not support audio.

Understanding the LED Indicators

The S1800e series devices have two types of tri-colored (red-orange-green)

LEDs: One system status LED and either 1, 8 or 16 video status LEDs depending

on the model.

System Status LED

The system status LED provides a visual indication on the current state of the

device.

LED Pattern Description

Steady red for 0.5 sec

and steady orange for

15 sec.

The encoder is powering up, phase 1 (bootloader

section).

Steady green The encoder is powering up, phase 2 (operating system

is starting up).

Flashing red (1 sec.

intervals)

The IP address is assigned to another device on the

network. The encoder is now using APIPA addressing

format.

Flashing green (1 sec.

intervals)

The firmware has started, the encoder is connected to

the network, but no serial data is transmitted.
