All items can be purchased from our website (www.sealevel.com) or by calling our sales team at 864-843-4343. · CA152 - Terminates the SIO-104 10 pin header to a DB9M connector. This termination provides the Sealevel Systems' DB9 standard for RS-422/485. 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. The following table shows several examples that typically do not cause a conflict. SW1 sets the I/O address for the SIO-104. Address Hex 280-287 2A0-2A7 2E8-2EF 2F8-2FF 3E8-3EF 300-307 328-32F 3F8-3FF Binary A9 A0 1010000XXX 1010100XXX 1011101XXX 1011111XXX 1111101XXX 1100000XXX 1100101XXX 1111111XXX Switch Position Setting 1 2 3 4 5 6 7 Off On Off On On On On Off On Off On Off On On Off On Off Off Off On Off Off On Off Off Off Off Off Off Off Off Off Off On Off Off Off On On On On On Off Off On On Off On Off Off Off Off Off Off Off Off Figure 1 - Address Selection Table 5 © Sealevel Systems, Inc. 3551 Manual | SL9122 9/2022 The following illustration shows the correlation between the DIP-switch setting and the address bits used to determine the base address. In the example below, address 300 is selected as a base. Address 300 in binary is XX11 0000 0XXX where X = a non-selectable address bit. A9 A3 EN ON 1 2 3 4 5 6 78 Figure 2 - DIP-Switch Illustration Setting the switch "On" or "Closed" corresponds to a "0" in the address, while leaving it "Off" or "Open" corresponds to a "1". 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 disabled, be sure to also disable the interrupt request for that port by removing the IRQ jumper at header J2. IRQ Selection The SIO-104 has an interrupt selection jumper, which should be set prior to use, if an interrupt is required by your application software. Consult the user manual for the application software being used to determine the proper setting. Position "R" is provided so that a jumper can be installed that connects a 1K-Ohm pulldown resistor to the output of a high-impedance tri-state driver which carries the IRQ signal. Because the IRQ line is driven low only by the pull-down resistor, it is possible for two or more boards to share the same IRQ signal. Position "R" installed is the default setting and should be left as is unless multiple cards are sharing a single IRQ. If multiple adapters are sharing a single IRQ, then only one adapter should have the pull-down resistor (position "R" selected) in the circuit. The IRQ can be set at jumper J2 for IRQ 2/9, 3-5, 7, 10, 11, 12, or 15. In the following example, the IRQ is set as IRQ4. 6 © Sealevel Systems, Inc. 3551 Manual | SL9122 9/2022 DIV1 DIV4 Figure 3 - Header J2, IRQ Selection (Factory Default) 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. 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 4 - Clocking Mode 'Divide by 4' To select the maximum data rate (460.8K bps) place the jumper in the divide by 1 (silk-screen DIV1) position.

However, in the event that device appears to not be functioning incorrectly, the following tips can eliminate most common problems without the need to call Technical Support. 1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be identified. 2. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e., SCSI adapters & on-board serial ports) do not. 4. For Windows operating systems, the diagnostic tool `WinSSD' is installed in the SeaCOM folder on the Start Menu during the setup process. First find the ports using the Device Manager, the use `WinSSD' to verify that the ports are functional. 5. Remember that a loopback test is not possible with the `NE' jumper in place. 6. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will help eliminate any software issues and identify any hardware conflicts.

This implementation has been defined and revised several times and is often referred to as RS-232-C/D/E or EIA/TIA-232-C/D/E. It is defined as "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. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard. This standard has defined as the "9-Position Non-Synchronous Interface between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange". Both implementations are in widespread use and will be referred to as RS-232 in this document. RS-232 is capable of operating at data rates up to 20K bps / 50 ft. The absolute maximum data rate may vary due to line conditions and cable lengths. RS-232 often operates at 38.4K bps over very short distances. The voltage levels defined by RS-232 range from -12 to +12 volts. RS232 is a single ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12 volts (usually +3 to +10 volts) represents a binary 0 (space) and -12 volts (-3 to -10 volts) denote a binary 1 (mark). The RS-232 and the EIA/TIA-574 specification define two types of interface circuits Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems Adapter is a DTE interface. 15 © Sealevel Systems, Inc. 3551 Manual | SL9122 9/2022 Appendix D PC/104 What is PC/104? The PC has become extremely popular in both general purpose (desktop) and dedicated (embedded) applications. Unfortunately, the PC has been hampered by the large size required to maintain PC compatibility. PC/104 addresses this by optimizing the PC bus in a form factor designed for embedded applications. Briefly, the key differences between PC/104 and the standard "AT" or ISA bus computer are as follows: · Reducing the form factor, to 3.550 by 3.775 inches · Eliminating the need for backplanes or card cages, through its self-stacking bus · Minimizing component count and power consumption (typically 1-2 Watts per module) by reducing required bus drive on most signals to 4 mA. Sealevel Systems has been a member of the PC/104 Consortium since its inception. Questions about the PC/104 Consortium can be sent to: PC/104 Consortium P. O.
