3.1.5. Broadcast Mode (Switch 8)
When enabled, permanently activates the Broadcast Mode. Data from the Control Port will be
sent out all eight Serial Ports. Note that when the Broadcast Mode is active, all Serial Port
Status LEDs will be lit.
Data received by the selected Serial Ports will be "ord" and passed out the Control Port. If
data is received by two ports simultaneously, data output may be garbled.
A broadcast one/all jumper located on the circuit board will block received data from Serial
Ports 2 - 8. This feature allows the Control Port to receive a response message from just one
device when broadcasting commands. Receiving data from multiple devices simultaneously
may cause garbled data.
