Wireless Modem Evaluation Board User’s Guide
Host Interface
The evaluation board supports RS-232 serial and TTL serial interfaces with hardware flow control. Parallel interfaces are not
supported by this evaluation platform.
Note: There are no buffers or drivers between the Socket Module and the evaluation board connectors. This provides the user direct
electrical access to all the signals on the Socket Module.
RS-232 Interface
The user can select the RS-232 by installing the RS-232 Select Jumpers on JP3 (Labeled ‘SERIAL I/F SELECT’ on Rev 1 of the
PCB). This connects the socket module serial interface signals to the on-board RS-232 interface. The output of the RS-232 interface
IC connects to the DB-9F connector. The RS-232 interface is fully voltage compliant and is configured as DCE (Data
Communication Equipment).
Note: The RS-232 and digital serial interfaces cannot be used at the same time.
Figure 10
DIGITAL SERIAL INTERFACE
The serial interface consists of serial receive and transmit data, flow control signals plus power and ground. These are digital CMOS
versions of the RS-232 interface signals. The voltage level is set by the voltage selection on the evaluation board or module installed.
WARNING: Note that these signals are connected directly to the Socket Module. They can be used as monitor points for the
RS-232 interface. If using the digital serial interface, be sure to remove the RS-232 select jumpers.
