1.6.1. Timing Specifications
Parameter
The diagram below shows 9XCite Modules providing an RF Link between hosts.
Figure 1‐03. System Block Diagram ‐ RF Link between hosts
The RF data flow sequence is initiated when the first byte of data is received by the transmitting
XCite Module. As long as XCite Module A is not already receiving RF data, the serial data goes into
the DI Buffer, is packetized, and then transmitted to XCite Module B.
