9XCite™ OEM RF Module – Product Manual v2.1 [2007.01.04]
2. RF Module Operation
2.1. Serial Communications
2.1.1. UART-Interfaced Data Flow
2.1.2. RS-232 and RS-485/422 Data Flow
The XCite OEM RF Module interfaces to a host device through a CMOS-level asynchronous serial
port. Through its serial port, the XCite Module can communicate directly with any UART-interfaced
or RS-232/485/422 device.
Devices that have a UART interface can connect directly through the pins of the XCite OEM RF
Module as is shown in the figure below.
Figure 2‐01. Data Flow in a UART‐interfaced environment
The XCite Module can enable a host device to communicate wirelessly. To transmit, the host device
simply sends serial data to the XCite Module pins. The XCite Module then converts the data into
FCC-approved RF data. Once transmitted, the RF data can be detected by receiving XCite Modules,
checked for integrity and then sent to a receiving device.
