RTS/CMD – Pin 5 (Input)

RTS The RTS signal (request to send) is not implemented for flow control

with the 9XStream modules. All received data (over-the-air) is sent out the

serial port regardless of the RTS signal.

CMD The 9XStream comes with a variety of configurable settings including

power-saving modes and network addressing options. This pin may be used

as a way to manually configure the 9XStream module. When this pin is

asserted (high), incoming serial data (on the DI pin) is interpreted as

commands instead of data. (See the Command Mode section of this manual.)

CONFIG – Pin 9 (Input)

The CONFIG pin (low-asserted) is used to force the module to enter AT

Command Mode. When asserted (low), the serial port baud rate is temporarily

set to match the default baud rate of the 9XStream module. This ensures that

the module will transition into AT Command Mode at a known baud rate.

Upon entering AT Command Mode, all configured parameters, including the

baud rate, remain in their saved state and can be modified as described in the

AT Command Mode section.

IMPORTANT:DO NOT tie the CONFIG pin to an external device as it

may cause problems with module operation. The

CONFIG pin should be tied to an external switch and

used manually to enter AT Command Mode only when

the AT Command Mode cannot be entered under the

normal procedure (see the

AT Command Mode

section).
