  • Page 3: Introduction

    The ULTRA SIO-104 provides a single field selectable port configurable as RS-422/485 supporting asynchronous data rates up to 460.8K bps. The ULTRA SIO-104 utilizes the Exar 16C850, which provides 128-byte, transmit and receive FIFOs. These larger buffers allow error free operation even in high-speed applications.

    Before You Get Started What’s Included The ULTRA SIO-104 is shipped with the following items. If any of these items is missing or damaged, please contact Sealevel for replacement. • ULTRA SIO-104 Adapter • Nylon Mounting Hardware Kit (PC304-NK) Advisory Conventions...

  • Page 5: Card Setup

    Sony (or compatible) 207M "9 Pin" connector. Card Setup The ULTRA SIO-104 contains several jumper straps for each port, which must be set for proper operation. Address Selection The ULTRA SIO-104 occupies eight consecutive I/O locations. A DIP-switch is used to set the base address for these locations.
  • Page 6 Port Enable / Disable The port on the ULTRA SIO-104 can be enabled or disabled with switch position 8 on the DIP-switch. The port is enabled with the switch “On” or “Closed” and disabled when “Off” or “Open” (refer to Figure 2). If the port is disabled, be sure to also disable the interrupt request for that port by removing the IRQ jumper at header J2.
  • Page 7 Some communication software packages refer to RS-485 as RTS enable or RTS block mode transfer. One of the unique features of the ULTRA SIO-104 is the ability to be RS-485 compatible without the need for special software or drivers. This ability is especially useful in Windows, Windows NT, and OS/2 environments where the lower level I/O control is abstracted from the application program.
