Connecting Serial Devices to the SMARTONE
The
SMART
ONE
accepts a serial connection at 3 volt levels (Max), at 9600
baud. The relevant pins are TX, RX, Handshake and ground. The
SMART
ONE
can
connect with devices that contain an asynchronous UART at 3 volt levels.
(High State: 2.7-3 Volts, Low State: 0 Volts.
Please contact Globalstar
Support for more information.
CAUTION:
NEVER attempt to connect the SMART
ONE
directly to the pins on a
computer's RS232 port. The voltages in RS232 are too high and can damage the
SMARTONE.
Any deviations from the above guidelines will violate all RMA requirements
and prevent any no-cost replacement.
