SeaI/O Hardware Description

SeaI/O Base and Expansion Modules

Base Modules connect to the host via one of the following interfaces:

 W-Series – Wireless Modbus TCP  E-Series - Ethernet Modbus TCP  U-Series - USB Modbus RTU  M-Series - RS-485 Modbus RTU  S-Series - RS-232 Modbus RTU

After the Base unit is installed, up to 246 additional SeaI/O N-Series Expansion Units can be added to create an I/O network. These expansion modules interface via

RS-485 and can be located local to the Base SeaI/O device or remotely located up to 4000 feet away. Local installations should use the 5” CAT5 RS-485 pass-through cable (Item number CA239) shipped with each N-series module to connect. Remote expansion modules should use RS-485 twisted pair wiring from the Base unit connected via the removable screw terminal connector.

For local installations power to the expansion modules is supplied from the Base unit via the pass-through connectors. For remote devices, separate power is required at each expansion unit. Refer to the Power Options section of this manual for more information on SeaI/O power requirements and power supply sizing.

Power Options

Base Module Power Connection

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).

SeaI/O Expansion Power Connection

Each SeaI/O product, including the expansion modules, contains an onboard switching regulator power supply rated for 9-30VDC. For local installations (less than 10’ apart), expansion unit power is usually supplied from the Base unit via the pass-through connectors. The number of expansion modules that can be driven from the Base unit depends on the power source and number/type of expansion units. Refer to the chart below for power requirements. For expansion modules mounted remotely (greater than 10’ apart), separate power is required at each expansion unit.

SeaI/O User Manual

Sample Power Calculation

A typical application for SeaI/O products would use one Base module and several Nseries units in a local expansion configuration. In this arrangement, with power applied to the Base module through either the DC jack or screw terminal connector and passed-through to the expansion units, attention should be given to ensure the input power to the Base module is adequate.

Example: Power (W) Base Unit: SeaI/O-430U 0.7 Expansion 1: SeaI/O-410N 1.4 Expansion 2: SeaI/O-440N 2.5

4.6W Power Required

In this application, the Sealevel Item# TR112 “wall wart” power supply is a good choice since it is low-cost and supplies 24VDC @ 250mA (6W).

NOTE:

A complete listing of recommended power supplies is provided in the Accessories section of this manual.

Communicating Via Modbus

Sealevel SeaI/O and SeaDAC modules are designed to integrate seamlessly into existing Modbus networks. The supported command set will vary depending on the SeaI/O model number used. Specialized diagnostic commands and other RTU specific codes are not supported. An overview of the Modbus specification for both RTU and TCP connections is covered in detail in the interactive documentation located on the Sealevel website at:

http://www.sealevel.com/software/SeaMAX/

The official Modbus specification can be found at:

SeaMAX Software Installation

Proceed with installing the SeaMAX Software Suite using the software CD 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

Windows 2000/XP/Vista™ Operating Systems

NOTE:

Important! Do not connect the I/O module to the host until the

software is installed.

1. Start Windows.

2. Insert the Sealevel Software CD in to your CD drive.

3. If ‘Auto-Start’ is enabled the installation window will automatically appear.

Otherwise, navigate to the root directory of your CD drive and double-click the ‘autorun.exe’ application to launch the installation window.

4. Select ‘Install Software’.

5. Select the Part Number for your device from the listing.

6. The setup file will automatically detect the operating environment and install

the proper components. Follow the information presented on the installation screens that follow.

7. A screen may appear with the declaration: “The publisher cannot be

determined due to the problems below: Authenticode signature not found.” Please select the ‘Yes’ button and proceed with the installation. This declaration simply means that the Operating System is not aware of the driver being loaded. It will not cause any harm to your system.

8. During setup, you may specify installation directories and other preferred

configurations. This program also adds entries to the system registry that are necessary for specifying the operating parameters for each driver. An uninstall option is included to remove the driver and all registry/INI file entries from your system.

9. Proceed with configuring your Sealevel I/O module using the MaxSSD

utility detailed on the following pages.

NOTE:

If you are using a Wireless (W-series) or Ethernet (E-series) SeaI/O module, skip ahead to either the Configuring a Wireless Module or Configuring an Ethernet Module sections of this manual, before using MaxSSD.

MaxSSD Configuration & Diagnostics Utility

The Sealevel Systems configuration utility, MaxSSD, is designed to simplify the installation, configuration, and diagnostics of Sealevel I/O modules. MaxSSD is a Microsoft Windows application and has been tested with Windows 2000, XP, and Vista.

Host PC Configuration Tab

The first time you run the MaxSSD utility (Start Æ All Programs Æ Sealevel SeaMAX Æ MaxSSD) it will default to the “Host PC Configuration” tab. This tab allows the user to choose the initial communication settings for the connected I/O device. The “COM Port” dropdown box allows the selection of a serial COM port (from COM1 to COM256), Ethernet (for Ethernet SeaI/O modules), or SeaDAC Lite (USB).

USB connected SeaI/O and SeaDAC modules are installed as virtual COM ports. Using device manager, expand “Ports (COM & LPT)” by clicking on the ‘+’ next to the category, and locate the COM port for your device and use it in the dropdown box in MaxSSD.

Once a COM port is selected, the baud rate and parity can be selected.

NOTE:

The baud rate and parity of the PC must match the settings of the Sealevel I/O module to be configured. The factory default settings for all Sealevel I/O modules are 9600 baud and no parity.
