The RED signal pin is also used to select Logic Level mode (instead of RS232) for connectBlue
product with internal RS232 driver. The mode functionality is not applicable on cB-0901 because
there is no internal RS232 driver available. To be compatible with these products check the data-
sheet about this signal.
The Red signal is not allowed to be pull-down when using the SerialSelect signals for
RS485/RS422 (see A.2.2.4).
A.2.3.2 RED Signal
The RED logic LED signal is not multiplexed with any other functionality, which makes the de-
sign more straightforward. See Figure 21 for a 3.3V design.
In a 5V system the high state output (2.8V) from the module is not enough to turn off the LED
so a 74HCT08 buffer can be used to raise the high level to 5V (see Figure 22).
The 74HCT08 gate is available in a single gate package (74AHCT1G08).

status of the signal can also be used as input to a
host controller.
