Addressing, data and control signals are TTL compatible. The ISO-16 is simple to operate. Inputs are simply read from their data ports. What’s Included The ISO-16 is shipped with the following items. If any of these items are missing or damaged, contact the supplier.
Card Setup Card Setup The ISO-16 contains several jumper straps for each port that must be set for proper operation. Address Selection The ISO-16 occupies 4 consecutive I/O locations. The DIP-switch (SW1) is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports.
Other inputs can be ‘wire OR ed.’ to also generate interrupts if desired. Please consult the factory for more information. 2/9 3 4 5 6 7 Figure 3 - IRQ Header E1 Sealevel Systems ISO-16 Page 3...
Installation Installation The ISO-16 can be installed in any ISA PC expansion slot. The ISO-16 contains a DIP-switch (SW1) and IRQ selection which must be set prior to installation. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover.
Technical Description Technical Description The ISO-16 provides four parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Port A and B are the input ports and are interfaced to optically- isolated inputs, while ports C and D unused. Assuming an I/O address of 300 Hex the following table shows the Port Addresses.

This can be done at the factory, if necessary. The input circuits are not designed for monitoring 120-volt AC circuits and damage will occur if connected to a 120-volt AC circuit. Sealevel Systems ISO-16 Page 6...
In all addressing modes, port numbers are zero-indexed; that is, the first port is port #0, the second port is #1, the third #2, and so on. Because the 3094 does not have any output ports, the mapping of relative and absolute addressing is the same. Sealevel Systems ISO-16 Page 8...

1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc. 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.
If possible, please have the adapter installed in a computer ready to run diagnostics. 3. Sealevel Systems maintains a Home page on the Internet. Our home page address is www.sealevel.com.
