Introduction Introduction Overview The Sealevel Systems ULTRA 530.PCI is a one channel PCI Bus serial I/O adapter for the PC and compatibles. It provides one field selectable RS-232/422/485/530 serial port supporting asynchronous data rates up to 460.8K 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.
Card Setup 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.

Only the I/O address may be modified by the user.
Card Setup Line Termination Typically, each end of the RS-485 bus must have line terminating resistors (RS-422 terminates at the receive end only). A 120-ohm resistor is across each RS-422/485 input in addition to a 1K ohm pull-up/pull-down combination that biases the receiver inputs. Header E4 allows customization of this interface to specific requirements. Each jumper position corresponds to a specific portion of the interface. If multiple ULTRA 530.
Card Setup Electrical Interface Selection Each port on the ULTRA 530.PCI has the ability to be used in either RS-232 or RS-422/485. This is selectable via four 24 pin DIP-shunts at E1-E4. Please use the following illustration to aid in the configuration of your electrical interface.

Card Setup Clock Modes The ULTRA 530.PCI employs a unique clocking option that allows the end user to select from divide by 4 and divide by 1 clocking modes. These modes are selected at Header E8. DIV1 DIV4 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 4 mode (silk-screen DIV4). Figure 10 - Clocking Mode ‘Divide By 4’ DIV1 DIV4 To select the maximum data rate (460.
Card Setup 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 Choose this Data Rate 300 bps 600 bps 1200 bps 2400 bps 4800 bps 14.4K bps 28.8K bps 57.6 K bps 115.
Card Setup Isochronous Clocking Jumpers The Oxford Semiconductor 16C950 allows for the reception of both the transmit and the receive clocks for isochronous communications (for a discussion on isochronous clocking refer to the Technical Description section). The three headers that allow the selection of either a modem control signal or the clock option are E5, E6 and E7. The following examples describe each setting.

Installation Installation Operating System Installation Windows 95/98/ME/NT/2000/XP 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.
Installation Physical Installation The adapter can be installed in any 5V PCI expansion slot and contains several jumper straps for each port that must be set for proper. 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 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.
Technical Description Technical Description The Sealevel Systems ULTRA 530.PCI 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.
