Introduction The ULTRA 530.LPCI is a one channel PCI Bus serial I/O adapter. It provides one field selectable RS-232/422/485/530 serial port supporting asynchronous data rates up to 921.6K bps as well as isochronous data rates up to the speed of the supplied clock. Now, with this card, you can use your standard communications software and connect over a clocked digital communications line. Configure the port as RS-232 for standard serial COM: port requirements.
Before You Get Started What’s Included The ULTRA 530.LPCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. ULTRA 530.LPCI Adapter Sealevel SeaI/O Software CD Optional Items Depending upon your application, you are likely to find one or more of the following items useful for interfacing the ULTRA 530.LPCI to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling (864) 843-4343.
Card Setup RS-485 Enable Modes RS-485 is ideal for multi-drop or network environments. RS-485 requires a tri-state driver that will allow the electrical presence of the driver to be removed from the line. The driver is in a tri-state or high impedance condition when this occurs. Only one driver may be active at a time and the other driver(s) must be tri-stated. The output modem control signal Request To Send (RTS) is typically used to control the state of the driver.
RS-485 Mode Examples (Header E5) Figure 1- Header E5, RS-422 Figure 2 – Header E5, RS-485 ‘Auto’ Enabled, with ‘No Echo’ Figure 3 - Header E5, RS-485 ‘Auto’ Enabled, with ‘Echo’ Figure 4 - Header E5, RS-485 ‘RTS’ Enabled, with ‘No Echo’ Figure 5 – Header E5, RS-485 ‘RTS’ Enabled, with ‘Echo’ © Sealevel Systems, Inc. -4- ULTRA 530.
Figure 6 – Header E5, RS-485 ‘DTR’ Enabled, with No Echo Address and IRQ selection The ULTRA 530.LPCI is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O address may be modified by the user. Adding or removing other hardware may change the assignment of I/O addresses and IRQs. Line Termination Typically, each end of the RS-485 bus must have line-terminating resistors (RS-422 terminates at the receive end only).
Electrical Interface Selection Each port on the ULTRA 530.LPCI has the ability to be used in either RS-232 or RS-422/485. This is selectable via two 24 pin DIP-shunts at E1and E2. Please use the following illustration to aid in the configuration of your electrical interface. Figure 8 - Headers E1 & E2, RS-232 Selected Figure 9 - Headers E1 & E2, RS-422/485 Selected © Sealevel Systems, Inc. -6- ULTRA 530.
Clock Modes The ULTRA 530.LPCI employs a unique clocking option that allows the end user to select from divide by 8 and divide by 1 clocking modes. These modes are selected at Header E6. To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, … 115.2K Bps ) place the jumper in the divide by 8 mode (silk-screen D8). Figure 10 - Clocking Mode ‘Divide By 8’ To select the maximum data rate (921.6K bps) place the jumper in the divide by 1 (silk-screen D1) position.
Baud Rates and Divisors for the ‘Div1’ mode The following table shows some common data rates and the rates you should choose to match them if using the adapter in the ‘Div1’ mode. For this Data Rate 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 57.6 K bps 115.2 K bps 230.4K bps 460.8K bps 921.6K bps Choose this Data Rate 150 bps 300 bps 600 bps 1200 bps 2400 bps 7200 bps 14.4 K bps 28.8 K bps 57.6K bps 115.
Software Installation Windows 98/ME/2000/XP Installation 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5. Select the Part Number for your adapter from the listing. 6. Select ‘Windows 98/ME/2000/XP’.
Linux Installation Note: You MUST have "root" privileges to install the software and drivers. 1. Login as "root". 2. Mount the CDROM by typing: mount -t iso4860 /dev/hdc /cdrom Note: Your cdrom may not be /dev/hdc it could be /dev/hda, /dev/hdb, /dev/hdd, or if you have a SCSI drive /dev/sda, /dev/sdb, /dev/sdc, etc. You may mount the CDROM to any location, the /cdrom is just a common example. 3. Next change to the directory where you mounted the CDROM: Ex.
Physical Installation The adapter can be installed in any 5V PCI expansion slot. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available 5V PCI slot and remove the blank metal slot cover. 4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5.
Technical Description The Sealevel Systems ULTRA 530.LPCI provides a PCI interface adapter with an additional asynchronous serial port providing a versatile interface, field selectable as RS-232 for modems, printers and plotters, as well as RS-422/485/530 for industrial automation and control applications. The ULTRA 530.LPCI utilizes the 16850 UART. This chip features programmable baud rates, data format, interrupt control and a 128-byte input and output FIFO. The ULTRA 530.

Appendix A - Troubleshooting Following these simple steps can eliminate most common problems. 1. Install software first. After installing the software then proceed to adding the hardware. This places the required installation files in the correct locations. 2. Read this manual thoroughly before attempting to install the adapter in your system. 3. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc.
Appendix B - How To Get Assistance Begin by reading through the Trouble Shooting Guide in Appendix A. If assistance is still needed please see below. When calling for technical assistance, please have your user manual and current adapter settings. If possible, please have the adapter installed in a computer ready to run diagnostics. Sealevel Systems provides an FAQ section on its web site. Please refer to this to answer many common questions. This section can be found at http://www.sealevel.com/faq.
Appendix C – Electrical Interface RS-232 Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard.
Appendix D – Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends. Asynchronous communications is the standard means of serial data communication for PC compatibles and PS/2 computers.
