It enables the host medical device to wirelessly establish bi directional communication with other remote devices using the Philips’ 2.4GHz ROW infrastructure. Page 3 of 8 3 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). Figure 2: MDL4851-MODULE Interface Host Connector Page 4 of 8 4 Pin Name I/O Function 1 Ground First of two ground connections for the module. 2 ITS_Tx OUT Serial data to host. 3 ITS_Rx IN Serial data from host. 4 Ground Second of two ground connections for the module. 5 +5 vdc + 5 vdc +/- 5%, Sinks 38 mA average, 320 mA Peak during radio Tx/Rx 6 Not Connected Table 1: Host Connector pin assignment 4 Serial Connection 4.1 Serial Specification: The interface to the Host is a serial communication link (Table 2): Æ Flow Control: Tx, Rx; no hardware flow control Æ Baud Rate: 115.2 kbaud; Æ Parity: No parity bit Æ Bits: 8 bits of data, plus 1 Start/Stop bits Æ Logic Levels: TTL levels, 5 volt tolerant. Logical Zero Logical One Conditions LOW HIGH 0.1 V max 100uA sink 0.55V max 24mA sink 2.9V min 100uA load ITS_Tx 2.3V min 24mA load ITS_Rx 0.6V max 2.2V min - Table 2: Serial Lines, Electrical DC Characteristics 4.2 Maximum User Data Rate: The maximum user data rate that the radio supports is 12 kbits/second in each direction. This maximum over the air data rate is fixed by design and cannot be modified by the user. Page 5 of 8 5 5 MDL4851-MODULE RF Shielding. The module contains all necessary RF shielding. The host device does not need to provide additional shielding. The available module metal enclosure is optional, it is not needed to achieve EMC compliance. Page 6 of 8 6 6 MDL4851-MODULE Mounting Considerations. The module is self-contained and can be mounted anywhere using the supplied threaded pem nuts. 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. However, antenna of equivalent gain & type to the qualified antennas can be used. The RF input and output of the MDL4851-MODULE is matched to 50 ohms. A coaxial cable brings the RF outside the metal enclosure. This cable uses a unique non standard connector manufactured by JST (JST part number AYUI-1S-12676-221). The coaxial cable connects to a JST to reversed TNC adapter made by Amphenol (Amphenol part number 031-6101) where the antenna plugs in. The antenna is made by Radial to Philips’ specifications (Philips specifications number A-M4842-61400-1, rev A). 7.1 RF Transmitter Specifications The following table summarizes general transmitter specifications (Table 3). For complete details (including details on the receiver section) refer to ES-M4840-90145: Parameter Specification Frequenc…
