Page 3: Introduction
Introduction The SIO-104 is the ultimate single port RS-232 serial connection for your PC/104 application. The 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. © Sealevel Systems, Inc. -

Before You Get Started What’s Included The SIO-I04 is shipped with the following items. If any of these items are missing or damaged, contact the supplier. (1) SIO-104 Serial Interface Adapter • • (1) Nylon Mounting Hardware Kit (PC304-NK) Advisory Conventions... -
Page 5: Card Setup
The SIO-104 contains several jumper straps for each port, which must be set for proper operation. Address Selection The SIO-104 occupies eight consecutive I/O locations. A DIP-switch is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing ports. - Page 6 Port Enable / Disable The port on the 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...
