Page 3 of 8 Figure 1: MDL4851-MODULE Block Diagram 3 Host Interface The MDL4851 radio module interfaces to the host though a single I/O connector (Figure 2). Via this connector the host must supply DC power, signal ground and modulating data to the radio module. The communication between the host device and the radio module is a two wire asynchronous serial interface (Table 1).

No special heat sinking considerations are required. There are no orientation constraints. 7 RF Input/Output, Antenna The MDL4851 Radio Module is approved for use with multiple antennas specified by Philips, part numbers M4842-61400 and M8100-66490. This antenna cannot be replaced with an antenna of a different type.
