Introduction Overview The SIO-104 series provides the ultimate serial connection for your PC/104 application. The SIO-104 is available in three different interfaces, RS-422/485, RS-232, and MIDI. The RS-422/485 model (P/N 3500) provides an interface capable of long length, high speed communications.
What’s Included The SIO-I04 is shipped with the following items. If any of these items are missing or damaged, contact the supplier. SIO-104 Serial Interface Adapter • • (1) DB-9 cable assembly (P/N 3500, 3501), or (1) MIDI cable assembly (P/N 3502) (1) Nylon Mounting Hardware Kit •...

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.

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...
Do not install the Adapter in the machine until the software has been fully installed. Extreme care should be taken when installing the SIO-104 to avoid causing damage to the connectors. After the adapter is installed, connect your I/O cables to J1-J4. Please note these headers are keyed so that pin 1 of the cable matches pin 1 of the connector.
The SIO-104-422 (P/N 3500) is equipped with the RS-422/485 interface allowing long length, high speed communications suitable for data collection and shop floor control. The SIO-104-232 (P/N 3501) provides a standard RS-232C interface that is fully compatible with the DOS operating system, all popular modem software, network operating systems software, and mouse drivers.
No two adapters can occupy the same I/O address. Make sure the Sealevel Systems adapter is using a unique IRQ The IRQ is typically selected via an on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and IRQ.
If possible, please have the adapter installed in a computer ready to run diagnostics. 3. 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.asp.
0 (space) and -12 volts (-3 to -10 volts) denotes a binary 1 (mark). The RS-232 and the EIA/TIA-574 specification defines two type of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface. RS-422 The RS-422 specification defines the electrical characteristics of balanced voltage digital interface circuits.
