The serial data and control lines are buffered using ESD protected RS-232 transceivers. Industry standard baud rates up to 921.6K bps are supported, together with 16-byte TX and RX FIFOs. A small switch is located at the back edge of the card, which allows selection of “x1” or “x8” baud rate multiplier. This feature allows up to 921.6K bps operation without needing special device drivers on the host (in x8 mode you simply multiply the setting shown on the host by 8 to get the real serial data rate - e.g. 19.2K bps set in software with “x8” mode gives 153.6K bps data rate physically in hardware). See section 5 for the switch settings. The SIO-232.CF conforms to the industry standard CompactFlash+ interface that allows connection of peripherals to the system bus of a laptop, handheld PC or PDA. The CF+ specification extends the earlier memory-only CompactFlash interface to allow I/O devices and extra power for the card. The SIO-232.CF is an I/O type device and requires a CF+ capable slot. © Sealevel Systems, Inc. - 2 - SIO-232.CF User Manual INSTALLING THE SIO-232.CF 3.1 Windows 95, 98, 98SE, Me, NT4, 2000, XP You will first need to install SeaCOM prior to using the SIO-232.CF. Installing the supplied SeaCOM software that comes with your product will copy the necessary files into the proper Windows folders. Windows will use these files to “recognize” the SIO-232.CF card. rd Note: Windows NT4 requires additional 3 party Card & Socket Services (additional charge, not included). 3.2 Windows CE, PocketPC There is no need to install any software for Windows CE or PocketPC. Simply insert the SIO- 232.CF card and it will appear in a list when you go to set up a “Connection”. © Sealevel Systems, Inc. - 3 - SIO-232.CF User Manual HARDWARE SPECIFICATION 4.1 PINOUT The SIO-232.CF is supplied with a 12” long cable that terminates with a DB-9M connector with female jackscrews (to match the port at the back of a PC). The pinout below applies to the SIO- 232.CF and the DB-9M connector on the supplied cable (the cable is pinned one-to-one). PIN NAME FUNCTION 1* DCD Data Carrier Detect input 2 RX Receive Data input 3 TX Transmit Data output 4 DTR Data Terminal Ready output 5 GND GROUND (0V) 6 DSR Data Set Ready input 7 RTS Request To Send output 8 CTS Clear To Send input 9 RI Ring Indicate input Shield - See note** * Pin 1 is nearest the edge of the card. ** The cable shield is grounded at the card-end, runs the full length of the cable and is not connected at the equipment end (i.e., does not connect to the DB-9 shell) to help to avoid ground loops. Technical Note: Please terminate any control signals that are not going to be used. The most common way to do this is connect RTS to CTS and RI. Also, connect DCD to DTR and DSR. Terminating these pins, if not used, will help insure you get the best performance from your adapter.

FORM FACTOR: 36.4mm x 42.8mm x 3.3 mm overall (1.43” x 1.68” x 0.13”) 4.5 ENVIRONMENTAL HUMIDITY: <80% R.H. (non-condensing) TEMP: 0-50°C ambient (32-122°F) 4.6 NOTES ON SERIAL DATA THROUGHPUT The maximum bit rate of 921.6K bps does not imply that the maximum sustained throughput rate of the serial port will be as high. The actual throughput that can be achieved depends on many factors including the host PC speed, the serial data block size, duty cycle, and overall host interrupt latency. © Sealevel Systems, Inc. - 5 - SIO-232.CF User Manual 4.7 BAUD RATE SETTINGS The table below illustrates the common baud rate values available for each of the baud rate multiplier switch positions: HOST SETTING SWITCH = x1 SWITCH = x8 300 bps 300 bps 2400 bps 1200 bps 1200 bps 9600 bps 2400 bps 2400 bps 19.2K bps 4800 bps 4800 bps 38.4K bps 9600 bps 9600 bps 76.8K bps 19.2K bps 19.2K bps 153.6K bps 38.4K bps 38.4K bps 307.2K bps 57.6K bps 57.6K bps 460.8K bps 115.2K bps 115.2K bps 921.6K bps © Sealevel Systems, Inc. - 6 - SIO-232.CF User Manual WARRANTY Sealevel's commitment to providing the best I/O solutions is reflected in the Lifetime Warranty that is standard on all Sealevel manufactured products.
