Introduction ACB-ULTRA.LPCI The ACB-ULTRA.LPCI adapter provides the PC with a single channel high-speed multi-protocol serial interface suitable for the most popular communication protocols. This sync/async card provides an ideal solution for high-speed applications including LAN/WAN connectivity. Utilizing the Zilog Z16C32 (IUSC™) on chip DMA controller eliminates bus bandwidth constraints that are placed on typical interface adapters, allowing data rates to reach 10M bps in burst mode.
Before You Get Started What’s Included The ACB-ULTRA.LPCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. ACB-ULTRA.LPCI Adapter o 5104 includes low profile PCI bracket o 5104S includes standard size PCI bracket 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 ACB-ULTRA.LPCI to real-world signals.
Software Installation Windows 95/98/ME/NT/2000/XP Installation Do not install the Adapter in the machine until the software has been fully installed. 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.
Physical Installation The adapter can be installed in any PCI (5V or 3.3 V) expansion slot. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available 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. Replace the screw. (This is required to ensure FCC Part 15 compliance.) 6.
Technical Description The Sealevel Systems’ ACB-ULTRA.LPCI adapter was designed for seamless integration into any PCI based system. The ACB-ULTRA.LPCI adapter requires a PCI slot, one IRQ, an 8 byte block of I/O address and a 16K block or 256K block of memory address and additionally, the IUSC requires a 256 byte block of memory. The memory range of this adapter can be configured to reside in the lower 1 Megabyte memory only or anywhere in upper memory. Low memory (not available on PCI 2.
Control and Status Registers Defined The control and status registers occupy 8 consecutive locations. The following tables provide a functional description of the bit positions.
Interface Selection The ACB-ULTRA.LPCI supports a variety of electrical interfaces. Reference the Control and Status Registers Defined section of this manual for this bit description. There is line termination on RXD, RXC, and TXC in the following modes: RS-530, RS-530A, RS-485T, and V.35. Reset Circuit Writing any value to base+3 will reset the Z16C32. Only one write is required. This starts a reset sequence, which lasts about 320 ns. During the reset sequence base+3 bit D4 will read 0.
I/O Signal Derivation The ACB-ULTRA.LPCI input/output signals are directly generated via the Zilog 16C32 IUSC. The following table defines these signals, their origin pin and signal name following the conventions set by the 16C32 user’s manual. If using a Sealevel Systems, Inc. supplied driver, this is for informational use only.

Appendix A – Troubleshooting Following these simple steps can eliminate most common problems. Install software first. After installing the software then proceed to adding the hardware. This places the required installation files in the correct locations. Read this manual thoroughly before attempting to install the adapter in your system. Use Device Manager under Windows to verify proper installation.
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. It is defined by the EIA as the Interface between Data Terminal Equipment and Data Circuit- Terminating Equipment Employing Serial Binary Data Interchange. The mechanical implementation of RS-232 is on a 25 pin D sub connector.
RS-530 / 530A RS-530 (a.k.a. EIA-530) compatibility means that RS-422 signal levels are met, and the pin-out for the DB-25 connector is specified. The EIA (Electronic Industry Association) created the RS-530 specification to detail the pin-out, and define a full set of modem control signals that can be used for regulating flow control and line status. The major difference between RS-530 and RS-530A lies in some of the modem control interface signals.
