Glossary

(cont.)

Serial data – Data that enters the 9XStream module through its serial port.

Serial port sleep – A Sleep Mode setting in which module runs in a low power

state until data is detected on the DI pin. This setting must be enabled using the

SM command.

Sleep Mode – A mode of operation in which the 9XStream enters a low power

consuming state. Several Sleep Mode settings are available and can be

configured using the SM command.

SLEEP pin – If Pin Sleep is enabled, the SLEEP pin (Pin 2) determines if the

module is in Sleep Mode or Idle Mode. See Pin sleep.

Standby Mode – See Idle Mode.

Start bit – A low UART signal sent to signify the beginning of an eight-bit data

sequence.

Stop bit – The last bit in a UART data sequence. The stop bit is high and

indicates the end of an eight-bit data sequence.

Synchronization – Synchronization is used to ensure that the transmitter and

receiver are communicating properly with each other and following the same

channel hopping sequence.

Transmission Latency – Time required to send a packet of data. This value is

dependent on the number of bytes being sent and the baud rate of the module.

Transmit Mode – Mode of operation in which over-the-air data can be

transmitted from a module to other modules.

TTL (Transistor-transistor logic)

UART (Universal Asynchronous Receiver-Transmitter) – See Serial port.

VID (Vendor Identification number) – This number allows modules with the

same VID to communicate. Any module with a different VID will not receive

their data transmissions.
