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.
