Introduction

• The SIO-232.CF card is an RS-232 serial card designed using a 16C550 compatible UART. 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.

Software Installation

Windows Installation

• Do not install the Adapter in the machine until the software has been fully installed.
• Only users running Windows 7 or newer should utilize these instructions for accessing and installing the appropriate driver via Sealevel’s website. If you are utilizing an operating system prior to Windows 7, please contact Sealevel by calling 864.843.4343 or emailing support@sealevel.com to receive access to the proper driver download and installation instructions.

You will first need to install SeaCOM prior to using the SIO-232.CF. Installing SeaCOM software that is available Sealevel’s website (www.sealevel.com) will copy the necessary files into the proper Windows folders. Windows will use these files to “recognize” the SIO-232.CF card.

1. Begin by locating, selecting, and installing the correct software: Sealevel Seacom Software.
2. Select the link for ‘SeaCOM for Windows’.
3. The setup file will automatically detect the operating environment and install the proper components.

To confirm that the SeaCOM driver has been successfully installed, click on the ‘Start’ button, and then select ‘All Programs’. You should see the ‘SeaCOM’ program folder listed.
You are now ready to proceed with connecting the 3101 to your system. Refer to the Hardware Specification section for details.

• Windows NT4 requires additional third-party Card & Socket Services (additional charge, not included)
• The diagnostic tool ‘WinSSD’ is installed in the SeaCOM folder on the Start Menu during the setup process. First find the ports using the Device Manager, then use ‘WinSSD’ to verify that the ports are functional.

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”.
For Windows CE and PocketPC, the utility ‘vxHpc’ is available from Cambridge Computer Corporation, free for a 30-day evaluation or a nominal charge for a license. ‘vxHpc’ is a high-performance serial and telnet communication software application that can help you connect to various terminal devices and can also be used to perform a simple loopback test.
The latest version and instructions are available here: https://web.archive.org/web/20101212202122/http://cam.com/vxhpc.html
For additional information on connecting your PocketPC or if you are using any other older versions of Windows, such as Windows 95/98/ME/NT/2000, please call Sealevel Systems’ Technical Support, 864-843-4343. Our technical support is free and available from 8:00 AM to 5:00 PM Eastern Time Monday through Friday. For email support contact support@sealevel.com.

Hardware Specification

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 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.
• 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.
• The mating connector type: Honda RMC-E9F2S-BSLA2N-A2

Electrical
All figures quoted are typical parameters @ 25°C (77°F)

• RS-232 SIGNALS: Typical output level ±5.5V (open circuit voltages)
• ESD PROTECTION: All RS-232 signal lines on the SIO-232.CF card are protected against electrostatic discharge (ESD)
  • 15kv – human body model
  • 8kv – IEC1000-4-2, contact discharge
  • 15kv – IEC1000-4-2, air-gap discharge
• UART CLOCK SPEED:
  • Switch selectable Baud rate multiplier:
  • x1: UART CLOCK is 1.8432MHz ->115.2K bps max
  • x8: UART CLOCK is 14.7456MHz -> 921.6K bps max

Power Consumption
All figures quoted are typical parameters @ 25°C (77°F)

• VCC CURRENT: 20mA typical @ 5V, 13mA typical @ 3.3V
• IN STANDBY MODE: 14mA typical @ 5V, 5mA typical @ 3.3V

Mechanical

• CARD MASS: 10g typical (0.352 oz.)
• FORM FACTOR: 36.4mm x 42.8mm x 3.3 mm overall (1.43” x 1.68” x 0.13”)

Environmental

• HUMIDITY: <80% R.H. (non-condensing)
• TEMP: 0-50°C ambient (32-122°F)

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.

The table below illustrates the common baud rate values available for each of the baud rate multiplier switch positions:

Appendix A – Troubleshooting

The adapter should provide years of trouble-free service. However, in the event that device appears to not be functioning incorrectly, the following tips can eliminate most common problems without the need to call Technical Support.

1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be identified.
2. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O space.
3. Try the Sealevel Systems adapter with a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e., SCSI adapters & on-board serial ports) do not.
4. Make sure the Sealevel Systems adapter is securely installed.
5. In Windows, the diagnostic tool ‘WinSSD’ is installed in the SeaCOM folder on the Start Menu during the setup process. First find the ports using the Device Manager, then use ‘WinSSD’ to verify that the ports are functional.
6. For Windows CE and PocketPC, the utility ‘vxHpc’ is available from Cambridge Computer Corporation, free for a 30-day evaluation or a nominal charge for a license. ‘vxHpc’ is a high-performance serial and telnet communication software application that can help you connect to various terminal devices and can also be used to perform a simple loopback test. The latest version and instructions are available here: https://web.archive.org/web/20101212202122/ http://cam.com/vxhpc.html
   7. Remember, if ‘No Echo’ mode is selected, a data loopback cannot be accomplished.
   8. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will help eliminate any software issues and identify any hardware conflicts.
   If these steps do not solve your problem, please call Sealevel Systems’ Technical Support, 864-843-4343. Our technical support is free and available from 8:00 AM to 5:00 PM Eastern Time Monday through Friday. For email support contact support@sealevel.com.
