All SeaI/O modules have a default baud rate of 9600. If lower latencies are required, the baud rate can be changed via the Sealevel utility, MaxSSD, included in your SeaMAX installation.
All modules, including expansion modules, must have the same baud rate or communications errors will occur.
To change the baud rate, connect to a SeaI/O module using MaxSSD. If you need to change the
baud rate of multiple devices, check the “Broadcast to Multiple Modules” box. Select the desired baud rate from the baud rate dropdown, and click “Set Settings.” If you are connected to the
modules via a COM port, you will need to reopen the COM port with the new baud rate.

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 (Part# 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 pass­through 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.
SeaI/O Manual

All SeaI/O modules include the same connectors and configuration options on the side of the unit:
RS-485 networks should have termination enabled on each end of the network. Pull-up and pull-down resistors should also be enabled on the last device on the network. The 9-30VDC input barrel connector is center positive.
Status LEDs are also included on the front of all SeaI/O modules to indicate the following information:
Communication (Yellow) – Blinks when data is transmitted Fault (Red) – Lights when there is a problem with the device Status (Green) – See Device Address Configuration section of this manual
o Blinks when the rotary “ADDR” switch is set to “0” and the default Slave ID is set to 247 o Lights steady when module is properly configured from the factory defaults

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, Vista and Windows 7.
When you run the MaxSSD utility (Start All Programs Sealevel SeaMAX 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), and Ethernet (for Ethernet and Wireless SeaI/O modules).
USB connected SeaI/O 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.
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.
To communicate with a SeaI/O Ethernet or Wireless 802.11b/g module, select “ETHERNET” from the “COM Port” dropdown box. When Ethernet is selected, MaxSSD searches for any SeaI/O Ethernet or Wireless modules on the network and displays their IP addresses in the “Available Ethernet Devices” list box (not shown). When an IP address is selected from the list box, a
socket is opened to the SeaI/O module and it is ready for communication.
If no IP address is shown when using Ethernet modules, review the previous Hardware Configuration section, or proceed to the Troubleshooting section at the end of this manual.
SeaI/O Manual
42
Once the host computer is configured correctly, the “SeaI/O Configuration” tab becomes
available. Before communicating with a SeaI/O module, the configuration utility must determine if there is an I/O module at that slave ID address, and if so, what type of module it is. This is the purpose of the Get operation.
To perform a Get operation, first select the slave ID to which the module is configured. SeaI/O modules are shipped at hardware setting 0 (labeled “ADDR” on the left side of the module) and slave ID 247 by default. All other slave ID addresses (from 1 to 246) are available. However, each daisy chained SeaI/O module must have a unique slave ID address - no duplicates are allowed.
Once a slave ID is selected, click the “Get SeaIO Module Settings” button. After a short delay,
the information for that I/O module should be displayed. If no information appears, verify the slave ID, host settings, and baud rates are correct and make changes, if necessary. Check the hardware settings (on the left side of the module) and try again.
SeaI/O Manual
43
After the Get command is executed, the “Module Description” frame will display the model type, description, firmware version number, interface, and I/O type. In the example shown, the module found at slave ID 247 is a SeaI/O-420 module with a USB (Modbus RTU) interface. The “Set Settings” and “Change Slave ID” buttons will also be enabled for this module.
After a successful Get operation, additional tabs may be displayed in MaxSSD, depending on the found device model. These tabs display device I/O and allow easy configuration for all SeaMAX supported devices.
The “Broadcast to Multiple Modules” checkbox, along with the “Set Settings” button can be used
to change the baud rate and parity on multiple SeaI/O modules at once. This function only works with SeaI/O modules connected together via the pass-through connectors.
MaxSSD broadcasts a set data rate and set parity command to all devices on the RS-485 bus, but only those modules listening at the current baud rate will be able to receive and respond. For example, if you have five SeaI/O modules chained together and two are set to 9600 bps and no parity and three are set to 115.2k bps and the PC is set to 9600 bps, only the two modules set to 9600 bps will receive the broadcast set data rate and parity message.
SeaI/O Manual
44
The broadcast feature sets the Ethernet SeaI/O (E-series) module‟s TCP/IP to RS-485 translation data rate independently of the SeaI/O module itself. If you set the data rate to
115.2K bps via a MaxSSD broadcast command, both the RS-485 port and the Ethernet port will respond thereafter to 115.2K bps, as expected. However, if you reset the SeaI/O module, by rotating the rotary switch clockwise one complete revolution, the RS-485 port will reset to 9600 bps and no parity, but the Ethernet port will remain unaffected. To restore communications, broadcast another set data rate and parity command (9600 and no parity) via MaxSSD.
SeaI/O Manual
45
The “Digital IO” tab of MaxSSD is displayed when using Sealevel I/O devices featuring discrete inputs and outputs. It displays the device‟s current input and/or output status in an intuitive
and usable manner.
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.
When banks of inputs are displayed, the status LEDs update on each of the banks automatically. This allows you to actively monitor external signals.
With a bank of outputs, the output coils can be set using the buttons below each output LED. As each coil is set, the I/O module is read. The corresponding status LED in the “Digital IO” tab indicates the state of the coil. In the example below, a SeaI/O module with 16 Reed relays is shown.
SeaI/O Manual
46
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. Input channels are displayed as banks (groups of eight). Each channel is range configurable via the voltage range dropdown list. Both the channel voltage range and device­wide configuration are set on a dropdown list. There is no need to save your settings – they are automatically saved to the device as you select the various configuration options.
“10x Hardware Gain Enabled” checkbox – Indicates whether or not the onboard hardware gain jumper is currently set. This option is not user configurable – it only reflects the status of the onboard hardware jumper settings. Set the hardware jumper to enable this functionality, which allows smaller voltages to be measured more accurately (e.g., a 0-1V input signal can be measured more accurately by enabling the 10x hardware gain jumper and setting the SeaI/O­470 A/D input channel for 0-10V range).
“Show Hexadecimal Values” checkbox – Displays the values returned by the A/D converter as a hexadecimal value without converting the values to engineering units (i.e., Amps or Volts)
SeaI/O Manual
47
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. Refer to the Hardware Configuration section of this manual for instructions on opening the enclosure and accessing the correct jumpers.
To adjust a particular channel‟s output voltage, drag the slider until the desired voltage is
displayed in the window on the right side. Also, you may type the desired voltage directly into the voltage display and then confirm your entry by pressing the „Enter‟ key on your keyboard.
The output voltage will not change until the „Enter‟ key is pressed or you have clicked on
the window anywhere outside of the text entry field.
SeaI/O Manual
48
To check basic functionality of both the A/D and D/A converters, press the “Diagnostics Utility”
button on the “D/A Outputs” tab (shown on the previous page) and then press the “Start” button, as shown below. Any errors will be shown in the “Results” pane. If any errors occur,
please contact technical support for further help.
To properly use the values returned from the SeaI/O-470 module‟s A/D channels, the application program must convert the returned values to engineering units (voltage). Likewise,
the application program must output the correct value to the I/O module‟s D/A outputs to
generate the desired voltage.
The conversion formulas will vary depending on how the I/O module is configured. The formulas and their uses are covered in detail in the interactive documentation located on the 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.
SeaI/O Manual

Following these simple steps can eliminate most common problems.
1. Read this manual thoroughly before attempting to install the device in your system.
2. Uninstall any previous versions of the SeaMAX software before installing any new
versions.
3. Install SeaMAX software before connecting any Sealevel I/O devices. Installing
the software places the necessary files in the proper locations on your system. After
installing the software, proceed with adding the hardware.
4. When installing SeaI/O modules, connect them one at a time. The “base” module
must be properly configured and communicating successfully with the host before
you can add additional expansion modules. Verify that each expansion module can
communicate before connecting additional expansion modules.
5. Confirm that all screw terminal connections are correct and secure and that the
correct cables are being used, including network cables (crossover vs. patch cables).
6. You can use standard network patch cables (straight-through cables) to connect
SeaI/O modules together via the pass-through connectors on the left side of the
module. Crossover cables should never be used to connect two or more SeaI/O
modules together. Crossover cables should only be used to connect an Ethernet
SeaI/O module to a host without going through an Ethernet hub or switch.
7. On SeaI/O modules, verify that the device address (slave ID) is properly set. Refer to
the Hardware Configuration section of this manual for instructions on setting the
device slave ID.
8. Use the MaxSSD utility, included on the software CD, to verify proper installation.
MaxSSD is designed to simplify the installation, configuration, and diagnostics of
Sealevel SeaI/O modules.
9. If the SeaI/O modules only sometimes respond to a Get operation or return invalid
data, you may have termination improperly set. Refer to the Hardware Configuration
section of this manual for instructions on properly setting line termination and pull-
up/pull-down resistors.
10. Refer to the Troubleshooting Ethernet & Wireless Modules section on the following
page for additional steps regarding Ethernet (E-series) SeaI/O modules.

All Ethernet (E-series) and Wireless (W-series) SeaI/O modules are shipped with DHCP enabled. If no DHCP server is available or the DHCP server cannot be reached, Ethernet SeaI/O modules default to a random IP address in the range 169.254.x.x. Wireless SeaI/O modules default to a random IP
address in the range 192.168.0.x. Change the PC‟s network settings to place both the SeaI/O module and PC on the same subnet. Adjust the SeaI/O module‟s IP address and Netmask using the
Ethernet Config utility (Start All Programs Sealevel SeaMAX Ethernet Config) installed with SeaMAX. Then restore the PC‟s network settings.
Problem: The SeaI/O module is visible in Ethernet Config, but the network settings cannot be changed.
The SeaI/O module is most likely on a different subnet than the PC. The PC‟s IP address and Netmask must be altered to place both the SeaI/O module and the PC within the same subnet. Contact your network administrator for assistance.
Problem: The SeaI/O module doesn’t show up in Ethernet Config.
Ethernet and Wireless SeaI/O modules are discovered via a UDP broadcast. Verify that any firewall software, such as Windows Firewall, ZoneAlarm, etc., or router settings that would hinder UDP transmissions are disabled.
It is also possible that the SeaI/O module may not be discovered if the PC and module are on
separate subnets. This may occur if the module‟s IP address is configured outside the range of the PC‟s subnet. It can also occur during a failed DHCP discovery. In either case, the “Recover Module”
button in Ethernet Config utility may be used to recover the device. Refer to the Hardware Configuration section of this manual for more information.
Problem: The rotary switch (ADDR) was used to reset an Ethernet (or Wireless) Sea I/O module, but it no longer responds to a ‘Get’ operation.
If you reset the SeaI/O module by rotating the rotary switch clockwise one full revolution, the RS­485 port will reset to 9600 bps and no parity, but the Ethernet port will remain unaffected.
The broadcast feature in MaxSSD sets the SeaI/O module‟s TCP/IP to RS-485 translation data rate independently of the SeaI/O module itself. Therefore, if you have an Ethernet or Wireless SeaI/O module and you set the data rate to 115.2K bps via a MaxSSD broadcast command, both the RS­485 port and the Ethernet port will respond thereafter to 115.2K bps, as expected. Using the rotary switch will reset the RS-485 port, but the Ethernet port will still try to communicate at 115.2k bps. To restore communications, broadcast a set data rate and parity command (9600 and no parity) via MaxSSD.
SeaI/O Manual
51
Before configuring SeaI/O modules using MaxSSD, you must first select a device addressing method. Next, you must properly set termination and pull-up/pull-down resistors. Finally, you must configure the SeaI/O modules one at a time before MaxSSD and any subsequent applications (using the SeaMAX API) will be able to successfully communicate.
SeaI/O modules have a rotary switch, labeled “ADDR”, located on the left side of the device that is used to
set the device address (slave ID). The default position for all SeaI/O modules is position “0” (zero). Each
SeaI/O module must be set to a unique slave ID in order to properly communicate with the host device, which
can be a computer or Modbus device. The slave ID can be set by hardware using the rotary switch, which is
recommended for most users. The slave ID can also be set in software by leaving the rotary switch at position
“0” and using MaxSSD to set the slave ID. The rotary switch has three functions:
Set Address (slave ID) via Hardware – If the rotary switch is set to a position between “1”
and “15” (F). The SeaI/O module will then always respond to commands issued at that slave
ID. This is useful when there are fewer than 16 SeaI/O modules in a chain and the slave ID
is not required to change. This method is recommended for most users.
Set Address (slave ID) via Software – If the rotary switch is left in the “0” (zero) position,
the SeaI/O module uses a default slave ID of 247 for communications. By using MaxSSD (or
the SeaMAX libraries), it is possible to set the slave ID to a software address between 1 and
247. This is useful when there are more than 16 SeaI/O modules in a chain, or when the
slave ID of a module needs to be frequently changed.
Hardware Reset – If you have an existing SeaI/O module set to an unknown slave ID or
baud rate, you may wish to reset the device. If the rotary switch is rotated clockwise one
full revolution, the SeaI/O module will be reset to factory defaults (slave ID 247, 9600 bps,
and no parity).
A Hardware Reset will not reset the communication rate of Ethernet (E-series) and Wireless (E-series) modules. Rotate the rotary switch clockwise one full revolution, and then use the MaxSSD utility to broadcast a set baud rate command to 9600 bps and no parity.
SeaI/O Manual
52
A “stack” or “chain” of SeaI/O modules, connected via the pass-through connectors or screw terminals on the left side of the enclosure, communicates via an RS-485 bus, which must be properly terminated to work correctly. A set of three dipswitches is located on the left side of enclosure, next to the “ADDR” rotary switch. These switches control line termination and the RS-485 pull-up and pull-down resistors.
The pull-up and pull-down resistors ensure that the input ports are at a known state when not being driven by the RS-485 line. In most cases, all three of the dipswitches on each SeaI/O module should be in the down position, except the two end modules. The first and last SeaI/O modules in the chain should have all three dipswitches in the up (enabled) position.
Make sure that only the first and last SeaI/O modules have line termination enabled (up position). Improper termination settings can result in invalid data or communication failures.
SeaI/O Manual
53
Once the SeaMAX Software Suite has been installed successfully and you have decided which address (slave ID) method you intend to use, start by connecting the first SeaI/O module to your computer. This will be referred to as the “base” module.
If you are chaining multiple SeaI/O modules together, only one SeaI/O module in the chain can be
the “base”. All other SeaI/O modules connected to the “base” module are referred to as expansion modules. Multiple “base” modules can be directly connected to a host computer, but expansion
modules must be connected (daisy chained) to a “base” module.
If you are configuring an Ethernet (E-series) or Wireless (W-series) SeaI/O module, skip ahead to the Configuring an Ethernet Module or Configuring a Wireless Module sections for specific information on installing those modules.
For all other SeaI/O modules (U-series, S-series, or M-series), locate the COM port by expanding the „Ports‟ list in Windows Device Manager.
Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and choose the
correct port (IP address or COM port) to communicate with the “base” module. Ensure a
successful Get operation (refer to the MaxSSD section on the following pages for more information).
Set the slave ID of the “base” module using the rotary switch or software selection method discussed in the Setting Device Address section on the previous pages. This
guarantees that any expansion modules connected next will not conflict with the “base”
module. Perform another Get operation to verify that you can communicate with the “base” module at the new slave ID.
Configure SeaI/O modules one at a time. Set the address to a hardware slave ID other than “0” or a software slave ID other than 247, which avoids device conflicts during setup.
After the “base” module is successfully communicating via MaxSSD, you can proceed with adding SeaI/O expansion modules (N-series) one at a time as required.
If the “base” module doesn‟t respond as expected, turn the rotary switch (ADDR) clockwise
one full revolution to reset. Configure the PC to communicate at 9600 bps and no parity and then try again.
SeaI/O Manual
54
Once you have successfully connected and communicated with a “base” module, you can begin
adding expansion modules (N-series). Connect a single expansion module to the “base” module via the RJ45 pass-through connectors or screw terminals on the left side of the enclosure. Expansion modules include a convenient 5” interconnect cable (Part# CA239) to simplify daisy-chaining SeaI/O modules together. Alternately, you can use standard network patch cables to chain expansion modules to a “base” module.
The RJ45 pass-through connectors on the left side of SeaI/O modules are not Ethernet connectors. Do not connect the ports to Ethernet enabled devices else damage to Ethernet devices will result.
Ensure a successful Get operation (refer to the MaxSSD section on the following pages for more information). Set the slave ID of the expansion module using the rotary switch or software selection method discussed in the Setting Device Address section on the preceding pages. Perform another Get operation to verify that you can communicate with the expansion module at the new slave ID.
Continue adding expansion modules (N-series) one at a time, until all modules have been successfully daisy-chained together and respond to a Get operation in MaxSSD. Once all SeaI/O modules are configured and communicating successfully, they are ready to communicate with your application.

Start by connecting power to the wireless SeaI/O module. The LEDs will blink to confirm that the unit is powered up and is ready to be configured to work with your wireless network.
The first time you power up the wireless SeaI/O module (and every time it is reset), it will take 20 seconds to “boot up” before it appears on the wireless network.
The wireless SeaI/O module ships in Ad Hoc mode by default and should be immediately visible with SSID of “SL_Recovery” to any computer equipped with a wireless adapter.
Most wireless adapters include a utility that allows you to see the wireless devices on your network. Please refer to the instructions included with your wireless adapter for details on how to locate wireless devices on your network. If the wireless SeaI/O module is not visible, you may need to adjust your security settings until you have successfully configured the wireless SeaI/O module.
Once you have confirmed that the wireless SeaI/O module is visible to your network, you can proceed with configuring the module. Instructions for configuring a SeaI/O module using Windows XP are detailed on the following pages.
* The channel number will increment each time a reset occurs. If you reset the module and can‟t see it on your wireless network, reset it again to increment the channel number up by one.
To reset the unit to factory defaults and increment the channel, locate the Reset button on the front of the module just above the antenna. Using a small rigid wire (e.g., paperclip), depress and hold the reset button. Power cycle the module by removing the barrel connector or terminal block supplying power to the unit, and then reconnecting the barrel connector or terminal block. Release the reset button and the SeaI/O module will be reset to the factory defaults and the channel number will increment up by one. The LEDs will blink to confirm that the SeaI/O module has been reset and is ready to be configured.
SeaI/O Manual
56
Verify that SeaMAX software has been installed successfully and that a wireless SeaI/O module is connected to power and ready to be configured to communicate with your wireless network. This module will become the “base” module.
To configure a wireless SeaI/O module, you must be using a laptop or desktop computer with a wireless 802.11b/g compatible adapter. The security settings on many wireless access points (WAP) prevent you from seeing Ad Hoc devices by default. Therefore, configuring a wireless SeaI/O module through a Wireless Access Point (WAP) is not supported.
1. Using a wireless enabled computer, connect to the Ad Hoc network “SL_Recovery”.
2. Move your wireless adapter to subnet 192.168.0.x.
3. Use the Ethernet Config utility to configure the wireless SeaI/O module to work with
your wireless network (SSID, topology, channel, and security) settings.
4. Using the same wireless enabled computer, connect to your wireless network.
5. Use the Ethernet Config utility to configure the wireless SeaI/O module to use the
same subnet as your wireless network.
6. Move your wireless adapter back to your wireless network subnet.
7. Use MaxSSD to configure the Slave ID of the wireless SeaI/O module and test
settings.

This information explains the various configuration options available. Continue with the wireless SeaI/O configuration on the following page.
The Network SSID (Service Set Identifier) is the name of the wireless network. The SSID can be up to 32 alphanumeric characters and is case-sensitive. If you are using the wireless SeaI/O module with a wireless access point (WAP), then the SSID names must match.
The network Topology defaults to Ad Hoc mode and supports Infrastructure mode. Ad Hoc mode is a point-to-point method used to communicate with other wireless network clients, including laptop computers and desktop computers using a wireless adapter. If you are using a WAP, select Infrastructure mode.
The network Channel will vary depending on the number of times the wireless SeaI/O module is reset. Every time the wireless SeaI/O module is reset, the channel will increment up by one. Since the wireless SeaI/O module supports channels 1-14, there is a chance that a reset can put the wireless SeaI/O module on a channel not compatible with your wireless adapter or access point. If you cannot see the wireless SeaI/O module on your network, try resetting the module

This device contains an FCC approved RF module. The transmitter carries FCC ID: R68WIPORTG.
This device has been designed to operate with the antennas listed in the Certificate, and having a maximum gain of 5 dB. Antennas not included in this list or having a gain greater than 5 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.
This module is authorized under limited module approval specified to mobile host equipment. So, the antenna must be installed such that 20cm is maintained between the antenna and users.
The transmitter module may not be co-located with any other transmitter or antenna.

This section applies only to Ethernet (E-series) SeaI/O modules. For all other SeaI/O modules, refer to the Configuring a “Base” SeaI/O Module and Configuring Expansion Modules sections on the previous pages.
Verify that SeaMAX software has been installed successfully and that an Ethernet SeaI/O module is connected directly to your computer using the yellow crossover cable supplied with your module. This module will become the “base” module.
All Ethernet SeaI/O modules are shipped with DHCP enabled. When you first connect an Ethernet SeaI/O module to the network, the status LEDs on the front of the module will blink while it searches for a DHCP server. Once it receives an IP address, the status LEDs will remain on.
If no DHCP server is available, the Ethernet SeaI/O module will default to a random IP address in the range 169.254.x.x. To discover the SeaI/O module‟s IP address, start the Ethernet Config utility (Start All Programs Sealevel SeaMAX Ethernet Config) installed with SeaMAX.
Click on the “Search for SeaI/O Devices” button and the „Available SeaI/O Devices‟ pane should
refresh with any Ethernet or Wireless SeaI/O modules that are found on the network. Select one of the modules in the list by clicking on it. You can update the settings in the Device Network
Settings pane and then confirm these changes by clicking the “Apply Changes” button. The module
list should refresh, indicating that your changes were successful.

Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and choose the correct IP address to communicate with the “base” Ethernet SeaI/O module. Ensure a successful Get operation (refer to the MaxSSD section of this manual for more information).
Set the slave ID of the “base” Ethernet SeaI/O module using the rotary switch or software selection method discussed in the Setting Device Address section on the previous pages. This guarantees
that any expansion modules connected next will not conflict with the “base” module. Perform
another Get operation to verify that you can communicate with the “base” Ethernet SeaI/O module at the new slave ID.
Configure the SeaI/O modules one at a time. Set the address to a hardware slave ID other
than “0” or a software slave ID other than 247, which avoids device conflicts during setup.
After the “base” Ethernet SeaI/O module is successfully communicating via MaxSSD, you can
proceed with adding SeaI/O expansion modules (N-series). Refer to the Configuring Expansion Modules section on the previous pages.
An Ethernet SeaI/O module may become no longer visible in the module list in the Ethernet Config utility if the Ethernet SeaI/O module has been configured to use a different subnet than the host computer.
In other cases, the Ethernet SeaI/O module doesn‟t appear in the module list due to a DHCP discovery failure. In either case, clicking on the “Recover Module” button (see image on
previous page) in the Ethernet Config utility will bring up the “Module Reset” window shown below.
SeaI/O Manual
75
Before recovery begins, make certain that the PC and Ethernet SeaI/O module are on the same network segment – they should be connected with an Ethernet crossover cable, through a hub, or through a non-routing switch. Ethernet SeaI/O modules are shipped with both an Ethernet patch cable (blue) and an Ethernet crossover cable (yellow).
Enter the MAC address found on the label on the bottom of the SeaI/O enclosure. A MAC address is made up of six pairs of hex digits separated by dashes (i.e., xx-xx-xx-xx-xx-xx). While entering the MAC address, the indicator to the right of the field will turn red if the MAC address entered is invalid. Once a MAC address is successfully entered, the indicator light will turn green and the “Network Settings” options will be enabled.
Contact your network administrator if you are unsure of the proper network settings to choose.
If a DHCP server is available, select the “Enable DHCP Configuration” checkbox. Otherwise,
complete the network settings and click the “Recover Module” button to complete the configuration changes.

Features was implemented. You may determine the version of your SeaIO device using the MODBUS command FUNC_SEAMAX_GET_EXTENDED_INFO (0x66), or by viewing the device info in MaxSSD, shown below.
In addition, the following modules do not support the Advanced Features:
462 463 470
In the event that a newer version of the firmware is available, it is possible to upgrade the firmware in the unit. This can be done through the same port that is used to do normal communications with the unit. The exception is when the unit is used with a wireless connection. In this case, the unit must be directly connected to the programming computer.
Since there is required interaction between the programming PC and the SeaIO module being programmed, this must be done in a situation where only one SeaIO module is connected to the programming computer.
Once you have the new programming file – this will be a file with a name similar to your SeaIO
model number with an extension of “.hex”. As an example, it you have a SeaIO 420 style module, the programming file name would be “420E.hex”.
When you are provided the file to be programmed, you will also receive the programming program. The name of this program is SeaIOCU.exe.
SeaI/O Manual
77
Since SeaIOCU.exe must be executed from a command prompt, the easiest way to use it is to copy SeaIOCU.exe and the hex file (in this example it is 420E.hex) to a subdirectory you create. For this example, we will create a subdirectory called c:\seaiocu.
Click on Start, then click Run and type “cmd” (without the quotation marks and hit enter. You
will then see a command prompt (c:\documents and settings\name>).
Type
Cd \seaiocu and then press Enter
At this point, we assume the SeaIO 420 unit is set for 9600 baud and address 247 (the default if the rotary switch is in position 0).
If you are connected either through a RS-232, RS-485, or USB connection then when the command calls for nnn you substitute you com port number. Note that it MUST be 3 digits. Therefore, if your com port is com5, you will enter 005. The command for this is therefore:
Seaiocu /c=005 /b=9600 /a=247 420e.hex
If you are connected through an Ethernet connection then when the command calls for
iii.iii.iii.iii you substitute the unit‟s IP address. Note that each group of numbers MUST be 3
digits. Therefore, if your IP address is 192.168.42.11, you will enter 192.168.042.011. The command for this is therefore:
Seaiocu /i=192.168.042.011 /a=247 420e.hex
The first thing the SeaIO unit will do is to erase all of its flash memory (with the exception of a small loader for the firmware). It will then start flashing all three lights rapidly indicating it requires downloading. Once the download starts, one light will flash as data is downloaded. Once the download is complete, the green light will remain on. At this point, simply unplug power to the unit and when power is re-applied, you should be operational with the new software.
In the event something about the download failed, the red light should stay on. In this case, simply power down the unit and power it back up. It should now be flashing all three lights rapidly. Simply perform the seaiocu command as described above.
The above should only be performed if you (1) really feel the update is required and (2) you feel confident in your ability to perform the update. Once the firmware has been erased, you must either be able to re-program it locally or send it back to SeaLevel Systems, Inc. for reprogramming.

Disabling the Rotary Address Switch and Limiting Software Address Range Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it:
462 463 470
As noted earlier, rotating the rotary switch from a non-zero address to the address zero position will reset the unit to the default state of address 247 and 9600 baud. There are many situations where this is not desirable. In the event you wish to disable the rotary switch or simply limit the range of software selectable addresses that may be set, you can do so by
sending the “WriteMultipleRegisters (function 0x16)” MODBUS command to the unit. Address
300 (decimal) should contain the low order byte of the lowest address the unit will accept. Address 301 will contain the high order byte. Once this command has been issued, the rotary switch will be completely ignored by the firmware.
To reset the unit to “normal” operation, you can issue the MODBUS “Broadcast Reset Message
(function 0x19).
This setting can also be configured through MaxSSD under the “Range Configuration” tab, shown below on the next page.

Limiting Expansion Port Communications Data Rate Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it:
462 463 470
There are situations where it is desirable to limit the range of allowable data rates or lock down
the unit to one specific data rate. This can be performed by sending the “WriteMultipleRegisters
(function 0x16)” MODBUS command to the unit. Address 302 (decimal) should contain the low order byte of the lower data rate the unit will accept. Address 303 will contain the high order byte. Note that this command does not cause the rotary switch to be ignored. Therefore, the rotary switch can be used to reset the defaults range and set the data rate back to 9600. If this is not desirable, then you can either set the data rate limitation and then set the address range to prevent the rotary switch from resetting to defaults or you can write to locations 300 through
303 in one “WriteMultipleRegisters” command.
To reset the unit to “normal” operation, you can issue the MODBUS “Reset Range Settings”
(function 0x19).
This setting can also be configured through MaxSSD under the “Range Configuration” tab, shown below.

This detail image of the right side of the SeaI/O-470 circuit board shows the locations of the user configurable jumpers and dipswitches. Refer to the following pages for instructions on properly configuring the jumpers and switches. The colored boxes are shown here for clarity and are not visible on the actual circuit board.
SeaI/O Manual
85
The (E1) and (E2) jumpers (shown in the orange boxes on the previous page) configure the D/A outputs for 0-5V or 0-10V. Both channels can be configured independently. The D/A outputs do not support negative voltages. You must also set the correct output voltage in your application or MaxSSD. Refer to the SeaMAX Application Suite section of this manual for help configuring software to work with the SeaI/O-470.
The A/D 10X gain (E3) jumper (shown in the green box on the previous page) is disabled at the factory. Position the hardware jumper on both pins to enable this functionality, which allows smaller voltages to be measured more accurately (e.g., a 0-1V input signal can be measured more accurately by enabling the 10x hardware gain jumper and setting the SeaI/O-470 A/D input channel for 0-10V range). You can also set the A/D input channel for 0-5V to sense voltages smaller than 0.5V.
When the jumper is enabled, the “10X Hardware Gain” checkbox will also be enabled on the A/D
Inputs tab in MaxSSD. Refer to the SeaMAX Application Suite section of this manual for information on using MaxSSD.
The (SW3) and (SW4) dipswitches (shown in the yellow box on the previous page) configure the A/D inputs for current loop mode and are disabled at the factory. Since current loop mode is differential, the corresponding dipswitch on both (SW3) and (SW4) should be properly set (e.g., „CH1‟ on both dipswitches needs to be set to „ON‟ to enable current loop mode).
SW3 – enables the current-loop sensing resistor
SW4 – ties the other half of connection to ground

All SeaI/O modules include two RS-485 pass-through connectors on the left side of the unit that are internally connected to the same pins on the screw terminals. This offers two convenient options for adding additional expansion modules.
For connecting several SeaI/O modules together in a “stack”, all N-series expansion modules ship with an expansion and strap kit (Part# KT122) that includes four metal straps, four #4-40 screws, and a 5” RJ45 RS-485 interconnect cable (Part# CA239). The metal straps allow you to securely connect multiple SeaI/O modules together. The interconnect cable can be used to connect SeaI/O modules together via the RJ45 pass-through connectors, providing an easy method to cascade RS­485 signals and power from one module to the next.
For expansion modules that are less than ten feet from a base unit, a standard RJ45 CAT5 patch cable (“straight-through”) may be used. For SeaI/O modules greater than ten feet apart, use twisted-pair cable connecting the data lines to the screw terminals instead. If RJ45 connectors are preferred, be sure to connect only the data lines (pins 4 and 5).
When using standard CAT5 patch cables to connect modules less than ten feet apart, ensure the cables are wired “straight-through.”
Do not connect network crossover cables to the pass-through connectors, else damage to equipment may result.
Modules greater than ten feet apart must have separate power supplies. Refer to the Power Options section of this manual for recommendations.

SeaI/O S-Series (RS-232) modules have an RJ45 connector on the face of the enclosure. Each S­series module includes a kit (Part# KT119) to convert the RJ45 RS-232 pin out to a standard DB9 RS-232 pin out. The kit ships with a DB-9F to RJ45 modular adapter (Part# DB109) with RS-232 pin out and a standard 7' CAT5 patch cable (Part# CA246). This kit allows SeaI/O S-series modules to be easily connected to a standard DB9 RS-232 serial port. For other interfacing options, the RJ45 serial pin out is shown below.
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.
