Glossary

(cont.)

Integration – The process of incorporating the 9XStream module into an

application in place of a serial cable.

Interface board – An optional board available with the 9XStream module that

converts RS-232-level data into CMOS logic levels.

Long header – A lengthy header (length determined by LH command – see

Appendix E) sent out to ensure that modules running in a cyclic sleep mode

detect the header when they awake and synchronize to the transmission.

Low-power modes – See Sleep Mode.

Module Addresses – Provides a layer of addressing among modules. Modules

with the same Module Addresses can communicate together.

Module Address Masks – Provide a layer of filtering to over-the-air data

packets that are received by the module. The address (of the transmitting

module) is logically “ANDed” with the Module Address Mask of the receiver.

The resulting value must match the Module Address of the receiver for the

packet to be received. All “0” values are not compared.

Networks – Provides a layer above Module Addresses for communicating

between modules. Each network has a unique hopping sequence that allows

modules on the same network to remain synchronized together.

Pin layout – Describes the layout and functionality of all pins on the 9XStream

module.

Pin sleep – A Sleep Mode setting which puts the 9XStream into a minimal

power state when the SLEEP pin is asserted. It remains in Pin sleep until the

SLEEP pin is de-asserted. This setting must be enabled using the SM command.

Power-saving modes – See Sleep Mode.

Receive Mode – A mode of operation that receives over-the-air data and

transmits all valid data packets out to the serial port. The module must be in Idle

Mode to transition to Receive Mode.

RS-232 logic – Standard logic levels implemented in devices using the RS-232

communication protocol.

RTS/CMD (Request to Send/Command) – The RTS/CMD pin (Pin 5) is used

primarily to configure Binary commands (CMD). RTS flow control is not

implemented in the 9XStream module.

Sensitivity – A measurement specification that describes how weak a signal can

be (in dBm) and still be detected by the receiver.
