Connecting the Speaker Cable

Remove the speaker cable from the BEETLE-CPU by simply unplugging

the connector. The BEETLE speaker is then inactive. The 4-pin plug con-

nector is next to the RAM module.

Use the TFT speaker

cable (delivered with

the system) to connect

the 4-pin-plug connec-

tor of the LCD-Control-

ler-A with the 4-pin

plug connector of the

BEETLE-CPU.

Connecting the speaker cable

If you do not connect the BA73A to a BEETLE-CPU but to

another commercially available PC, please pay attention to

the pin assignment of the speaker. A loudspeaker cable for

a PC is not included in the delivery unit.
