An application board, the

Z3-DM8107-APP-21

, is included with the Z3-DM8107-SDI2-RPS

This application

board uses the I/O expansion capability of the

Z3-DM8107-MOD

to implement additional functions not

present in the base module. The

Z3-DM8107-APP-21

application board has 1 SDI input, 1 HDMI output, and

a port for composite/analog audio input.

Figure 2

below shows an image of a Z3-DM8107-APP-21

application board:

A Linux-based SDK, additional design services, and support are available from Z3 Technology. Please
