• 9600 bps data rate, 8 data bits, 1 stop bit, no parity.
The COM port data rate is stored in NVRAM. The (factory) default data rate in NVRAM is
1200 bps, with CCU jumper W1 set for software control.
If the data rate is not set, select the bottom two pins of W1 for software control of the data
rate. Otherwise, with jumper W1 set on the top two pins the data rate is set to a fixed
1200 bps.
Note: Be sure to set the system control terminal to the same data rate as the D/I Mux III.
Jumper W2 on the CCU board selects which communications protocol is used by the D/I
Mux III. With W2 set to the bottom position, the D/I Mux III is controlled by standard
terminals using ASCII code. With W2 set to the top position the D/I Mux III is controlled
with Coastcom proprietary language.
Front Panel LEDs
Front panel Light Emitting Diodes (LEDs) indicate the current status of the CCU. The
control terminal of the D/I Mux III will also display the indicator status.
