The REL-32 is PC compatible and fits any ISA or EISA slot. Addressing, data and control signals are TTL compatible. The REL-32 is simple to operate. By writing instruction bytes to the I/O port addresses, the reed relays are energized or de-energized. What’s Included The REL-32 is shipped with the following items. If any of these items are missing or damaged, contact the supplier. · REL-32 Relay Interface Adapter · 3.5” DIO Diskette · User manual Factory Default Settings The REL-32 factory default settings are as follows: Base Address 300 To install the REL-32 using factory default settings, refer to Installation on page 5. For your reference, record installed REL-32 settings below: Base Address Sealevel Systems REL-32 Page 1 Card Setup Card Setup The REL-32 contains several jumper straps for each port which must be set for proper operation. Address Selection The REL-32 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. The following table shows several examples that usually do not cause a conflict.

In the example below, address 300 is selected as the base address. Address 300 in binary is XXX 100000 XXX where X = a non-selectable address bit and address bit A9 is always a 1.

This connects the B-side of the relay banks to ground, which appear at the on-board DB-37. Sealevel Systems REL-32 Page 3 Card Setup Header JP1 Header JP1 provides a means of connecting +5 VDC and +12 VDC from the PC bus, to the Options Header. The center pin of this header is connected to P3 pins 33-36. JP1 Figure 4 - Header JP1 (Factory Default +5V) Optional Cable Connector P4 Discrete access to both sides of all relays is provided by attaching the optional cable (CA-108) to pin header P4 with the colored edge of the ribbon cable attached to pin one. Removing all the jumpers connecting row P1 to P2 places the A-side of each relay at the on-board DB-37 and the B-side at the optional cable’s DB-37. Sealevel Systems REL-32 Page 4 Installation Installation The REL-32 can be installed in any of the PC expansion slots.

Sealevel Systems REL-32 Page 7 Technical Description Programming Application Programmers Interface (API) Most modern operating systems do not allow direct hardware access. The SeaIO driver and API have been included to provide control over the hardware in Windows and Linux environments. The purpose of this section of the manual is to help the customer with the mapping of the API to the actual relays for the 3098 specifically. Complete documentation of the API can be found in its accompanying help file. Relative Addressing Vs. Absolute Addressing The SeaIO API makes a distinction between “absolute” and “relative” addressing modes. In absolute addressing mode, the Port argument to the API function acts as a simple byte offset from the base I/O address of the device. For instance, Port #0 refers to the I/O address base + 0; Port #1 refers to the I/O address base + 1. Relative addressing mode, on the other hand, refers to input and output ports in a logical fashion. With a Port argument of 0 and an API function th meant to output data, the first (0 ) output port on the device will be utilized. Likewise, with a Port argument of 0 and an API function th designed to input data, the first (0 ) input port of the device will be utilized. 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. Due to the fact that the 3098 has no inputs the relative and absolute address for each relay are the same.

Sealevel Systems REL-32 Page 13 Appendix C - Electrical Interface Appendix C - Electrical Interface Reed relays provide very high quality, long life, low current (10 Watt maximum), dry contact switch closures. Reed relays are not suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs across the contacts internally. The relays are normally open, and close when energized. Each relay can be individually energized by writing a "1" to the proper port bit.
