Page 35 Base modules are powered from a 9-30VDC source using either the DC jack or screw terminals on the side of the unit. Sealevel offers several power supply choices to make connection easy (see the Accessories chapter at the end of this document).
Page 36 SeaI/O-440N 4.6W Power Required In this application, Sealevel‟s Part# TR112 “wall wart” power supply is a good choice since it is low-cost and supplies 24VDC @ 250mA (6W). A complete listing of recommended power supplies is provided in the Accessories section of this manual.
Page 37 The SeaMAX Suite is a collection of configuration/diagnostic utilities and software libraries that enable rapid application development. The SeaMAX API, included in the SeaMAX Suite, provides a common API for Sealevel SeaI/O and SeaDAC data acquisition modules. SeaMAX is designed to simplify application development by requiring little knowledge of the underlying communication protocols of these devices and replacing low-level programming.
Page 38 Proceed with installing the SeaMAX Software Suite using the software disk that was included with your Sealevel I/O module. Software drivers are also available on the product webpage on the Sealevel website at www.sealevel.com. Do not connect the I/O module to the host until the software is installed.
Page 39 Next follow the information presented on the screens that follow. Once the installation is complete, close the disk installation window. 11. Refer to the Physical Installation section to connect and install your adapter. ©Sealevel Systems, Inc. SeaI/O Manual SL9049 - 06/2011...

Page 46 When displaying SeaI/O, the “Digital IO” tab displays inputs and outputs in groupings (or banks) of eight. Therefore, a Sealevel I/O device with 16 inputs and 8 outputs would show two banks of inputs and one bank of outputs.
Page 47 The “A/D Inputs” tab displays the current state of the analog-to-digital channels for Sealevel I/O devices that feature A/D inputs. Settings are provided for both device wide and per-channel configuration. The “Device Configuration” selection drop-box adjusts the arrangement and function of the A/D input channels.
Page 48 The “D/A Outputs” tab is useful for manually setting the digital to analog output voltages on applicable Sealevel I/O devices with D/A channels. A preliminary diagnostics utility (see following page) has been provided to verify proper hardware functionality. The D/A outputs of the SeaI/O-470 are factory set for 0-10V. To configure the D/A outputs for 0-5V, you will need to open the enclosure and set the correct jumpers.
Page 49 Sealevel website at http://www.sealevel.com/software/SeaMAX/. For ease of use, SeaMAX functions to convert A/D and D/A values have been provided. Use of these functions is also detailed in the SeaMAX Software Manual.

The above connection scheme is designed to eliminate this ground potential difference from the measurement. ©Sealevel Systems, Inc. SeaI/O Manual SL9049 - 06/2011...
Page 103 For SeaI/O S-series modules, pin 4 of the RJ45 connector outputs 5VDC @300mA. This is useful for powering the wireless Bluetooth adapter (Sealevel Part# BT-SD100). This allows any Bluetooth capable host to access a SeaI/O module as easily as communicating with a standard RS-232 serial port.

Page 105 B connector, the metal thumbscrew provides a secure metal-to-metal connection to the module and prevents accidental cable disconnection. Sealevel incorporates SeaLATCH locking USB ports on many USB hubs and I/O devices. Accidental cable disconnection is the most common point of failure with USB industrial I/O devices and SeaLATCH cables and connectors prevents that while being fully compatible with standard USB cables.
