Test Keypad Connection
At the top right of MacroMaster684, click on Test. This will launch the key test
program.
If you click on Get Version, the 684 will respond with it’s version string. You may
also press the keys on the 684. You should see some characters appear in the
[Data from Keypad] area. Depending on what key codes have been
programmed, this information may appear as nonsense. Also if the baud rate
does not match between the keypad and the test program, you might see only
gibberish.
