Introduction
Sealevel Systems REL-16 Page 1
Introduction
Overview
The REL-16 provides 16 reed relays that can latch power, data or other
electronic signals for control applications. The REL-16 is PC compatible and
fits any half length ISA or EISA slot. Addressing, data and control signals are
TTL compatible.
The REL-16 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-16 is shipped with the following items. If any of these items are
missing or damaged, contact the supplier.
•REL-16 Interface Adapter
•Relay/Digital I/O Software
•User manual
Factory Default Settings
The REL-16 factory default settings are as follows:
Base Address IRQ
300 5
To install the REL-16 using factory default settings, refer to Installation on
page 3.
For your reference, record installed REL-16 settings below:

Installation
Sealevel Systems REL-16 Page 2
Card Setup
The REL-16 contains several jumper straps for each port which must be set for
proper operation.
Address Selection
The REL-16 occupies a total of 2 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.

Figure 1-Address Selection Table
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 302 is selected as the base address. Address 302 in binary is
XX 11 0000 00XX where X= a non-selectable address bit and address bit A9
is always a 1.

Note: Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address,
while leaving it ‘Off’ or ‘Open’ corresponds to a ‘1’.

Installation
Sealevel Systems REL-16 Page 3
Installation
The REL-16 can be installed in any ISA PC expansion slot. The REL-16
contains a DIP-switch (SW1) which must be set prior to installation.
1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an two available slots and remove the blank metal slot covers.
4. Gently insert the REL-16 into the slot. Make sure the adapter is seated
properly.
5. Replace the cover.
6. Connect the power cord.
Installation is complete.
Software Installation
For Windows Users
Choose Install Software at the beginning of the CD and select the Digital I/O
software drivers and install SeaIO.

Technical Description
Sealevel Systems REL-16 Page 4
Technical Description
The REL-16 provides two output (I/O) ports. The ports are organized as ports
A and B and are reed relay output ports. Assuming an I/O address of 302 Hex
the following table shows the Port Addresses.
Base Address Hex Decimal Mode
300 768 Unused
301 769 Unused
Port A Address 302 770 Output Port (Reed Relays)
Port B Address 303 771 Output Port
Please note that ports A and B are output ports with read-back capability,
meaning that they can be written (output) to and then read back as inputs. What
ever was written will always be read back (binary complement). This allows for
bits to be set or reset without altering the state of the other port bits.
Features
•Selectable I/O port addressing from 100H -3FFH
•2 sets SPST relays with each set having 8 relays
•DB-37 male connector for relay outputs
•Highly reliable 10 VA DIP reed relays utilized
•8 bit slot connector
•Multiple adapters can reside in same computer
•All address, data and control signals are TTL compatible

Technical Description
Sealevel Systems REL-16 Page 5
Output Ports (Reed Relay)
The output ports on the REL-16 relay output are connected to 16 dip reed
relays. 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.
Relay Specifications
•Contact Power Ratings: 10 Watts Maximum
•Contact Voltage Maximum: 100 Volts DC or AC Maximum
•Contact Current Maximum: .5 Amps DC or AC RMS
•Contact Resistance, Initial: .15 Ohms
•Rated Life:

Maximum Load: 100 Million Closures

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 3095 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 meant to
output data, the first (0th) output port on the device will be utilized. Likewise,
with a Port argument of 0 and an API function designed to input data, the first
(0th) 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.

Direct Hardware Control
In systems where the users program has direct access to the hardware (DOS)
the table below gives the mapping and functions that the 3095 provides, a base
address of 300 was used. If a different base address is used then the port
addresses are calculated as shown in the table.
Reading the Outputs (relays) (direct) :
The relay ports return the ones complement of the value that is currently being
used to drive the relays. When using the API the value is returned not the
complement of the value.
Writing the Outputs (relays) (direct) :
The output ports are the only ports that can be written. The relays on a standard
3095 are normally open. To close a relay a one must be written to the
appropriate bit.
R = Read
W = Write
R/W = Read or Write
