9XCite

Wireless OEM Module

Powerfully Simple

The 9XCite Module is a drop-in wireless solution that adds connectivity to any UART or serial

device. It transfers a standard asynchronous serial data stream and features the following:

• Continuous data stream of up to 38400 bps (factory-set, over-the-air baud rate)

• Serial Interfacing from 1200 to 57600 bps

• Software selectable between Hopping (FHSS) and Single Channel modes

• Approved by the FCC under Part 15 of the FCC Rules and Regulations

• Variable input supply voltage (2.85 – 5.50 VDC)

This manual contains information critical to basic 9XCite Module operation. More detailed

information is available in the “XCite Advanced Programming & Configuration” Manual. (Located

Pinout Signal Overview

The interface signals are available through the 11-pin header. All pins operate on VCC CMOS

levels. Five signals that are commonly used in applications are:

• DI (pin 4 – Data In)

• DO (pin 3 – Data Out)

• VCC (pin 10 – Power)

• GND (pin 11 – Ground)

•

The remaining 6 pins (SLEEP (PWRDN),

additional functionality. Go to the “XCite Advanced Programming & Configuration Manual” for

more detailed information about module pinouts.

Serial Data

Data enters the 9XCite Module through the DI Pin as an asynchronous serial signal. The signal

should idle high when no data is being transmitted.

Each data packet consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit

(high). The following figure illustrates the serial bit pattern of data passing through the module.

Figure 3. UART data packet 0x1F (decimal number “31”) as transmitted through the 9XCite Module

The 9XCite Modules transfer 7 or 8 bits over-the-air [Selectable using BI Parameter]. The start

and stop bits from the UART signal are not transmitted, but are regenerated on the receiving

module.

DI (Data In) Buffer

Once serial data has entered the 9XCite Module through the Data In (DI) Pin, the data is stored

in the DI Buffer until it can be transmitted.

Once the first byte of data enters the DI Buffer, the module begins to initialize the RF channel

(unless RF data is being received). In the case where the module is receiving RF data, the serial

data is stored in the DI Buffer. When the DI Buffer has only 17 bytes of memory left, the 9XCite

Module de-asserts (high)

once the DI Buffer has at least 35 bytes available in memory. Once in the DI Buffer, the data is

packetized for transmission. [The packet structure is broken down on the next page.]

The RF data flow sequence is initiated when the first byte of data is received by the transmitting

9XCite Module. As long as 9XCite Module A is not already receiving data, the serial data goes into

the DI Buffer, is packetized and then transmitted to 9XCite Module B.
