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.

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.

- 23 -

SeaI/O User Manual

Host PC Configuration Tab (continued)

To communicate with a SeaDAC Lite module, select “SeaDAC Lite” from the “COM Port” dropdown box. MAXSSD will search for any SeaDAC Lite modules connected to a USB port and display them in a frame (as shown below). A new “Digital I/O” tab will appear. If more than one SeaDAC Lite module is connected, select the one you want to test from the list and click the “Digital I/O tab”. You can use this new tab to test the functionality of inputs and relay outputs. The “Digital I/O” tab is covered in detail on subsequent pages.

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.

NOTE:

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 User Manual

SeaI/O Configuration Tab

Once the host computer is configured correctly, the “SeaI/O Configuration” tab becomes available. This tab only appears for SeaI/O and SeaDAC modules and will not appear when using SeaDAC Lite modules.

Before communicating with a SeaI/O or SeaDAC 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.

SeaDAC modules are only available on slave ID 247, and this number cannot be changed. To communicate with a different SeaDAC module, select a different COM port. Use device manager, if necessary, to locate the proper COM port.

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 host settings and baud rates are correct and make changes, if necessary. For SeaDAC modules, make sure the baud rate is set to 9600bps. For SeaI/O modules, check the hardware settings (on the left side of the module) and try again.

- 25 -

SeaI/O User Manual

SeaI/O Configuration Tab (continued)

After the Get command is executed, the “Module Description” frame will display the model type, description, interface, and I/O type. In the example shown, the module found at slave ID 247 is a SeaI/O-410 module with an Ethernet (Modbus TCP) 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.

- 26 -

SeaI/O User Manual

SeaI/O Configuration Tab (continued)

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 passthrough connectors. This function is disabled with SeaDAC and SeaDAC Lite modules since these devices do not have pass-through connectors.

MaxSSD broadcasts a set data rate and set parity command to all devices on the RS485 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.

NOTE:

Important! Ethernet (E-series) and Wireless (W-series) modules

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 User Manual

Digital I/O Tab

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 or SeaDAC modules (excluding SeaDAC Lite), 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” window indicates the state of the coil. In the example below, a SeaI/O module with 16 Reed relays is shown.

- 28 -

SeaI/O User Manual

Digital I/O Tab (continued)

When displaying SeaDAC Lite modules, the “Digital IO” tab displays inputs and outputs in groupings (or banks) of four. Therefore, a SeaDAC Lite module with four inputs and four outputs would show only one bank 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 SeaDAC Lite module is read. The corresponding status LED in the “Digital IO” window indicates the state of the coil. In the example below, a SeaDAC Lite module with four inputs and four Form C relays is shown, with the state of the relays showing either normally-open (NO) or normally-closed (NC).

NOTE:

The “SeaI/O Configuration” tab does not appear in MaxSSD when using SeaDAC Lite modules since they have no configurable communication settings.

- 29 -

SeaI/O User Manual

Programmable I/O Tab

The “Programmable IO” tab of MaxSSD is displayed when using Sealevel I/O devices featuring programmable inputs or outputs. This tab allows for bank configuration, input/output configuration, as well as bit-level presets.

Each bank of programmable I/O can be set as either an 8-bit group of inputs or outputs. By selecting “Bank 1” from the drop-box, clicking the “Bank functions as Input” radio button, and then clicking the “Set Programmable IO Options” button, the first 8 PIO bits on the device will now function as inputs. For ease of configuration, an “All Banks of IO” option is available to configure all of the I/O at one time.

Inputs have no preset mode; therefore, the preset options are disabled for any bank of inputs. Outputs; however, have bit-addressable presets. These presets are used whenever the device is powered up or the bank direction changes from input to output.

NOTE:

The output presets, will not lock the outputs into a specified on or off state. They only set the state of the outputs on a power on or bank direction change.

SeaI/O User Manual

A/D Inputs Tab

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 device-wide 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/O-470 A/D input channel for 0-10V range).

“Show 12-Bit Hex 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)

- 31 -

SeaI/O User Manual

D/A Outputs Tab

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 and SeaDAC 8227 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.

NOTE:

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.

A/D & D/A Diagnostics

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.

Converting A/D & D/A Values

To properly use the values returned from the SeaI/O-470 and SeaDAC 8227 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:

SeaI/O User Manual

Troubleshooting SeaMAX

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 first, 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.

11. If these steps do not solve your problem, please contact Sealevel Technical Support.

SeaI/O User Manual

Troubleshooting Ethernet & Wireless SeaI/O Modules

Problem: The SeaI/O module starts up with a strange IP address (i.e., 169.254.x.x)

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 Æ All Programs Æ Sealevel SeaMAX Æ 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) SeaI/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 RS-485 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 RS-485 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 User Manual

Hardware Configuration

Setting Device Address (Slave ID)

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).

NOTE:

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.

- 36 -

SeaI/O User Manual

Setting Termination & Pull-Up/Pull-Down Resistors

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.

NOTE:

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.

- 37 -

SeaI/O User Manual

Configuring the “Base” SeaI/O Module

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.

NOTE:

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 Æ All Programs Æ Sealevel SeaMAX Æ 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.

NOTE:

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.

NOTE:

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.

- 38 -

SeaI/O User Manual

Configuring N-Series Expansion Modules

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 (item# 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.

NOTE:

CAUTION! 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.

Configuring a Wireless (W-Series) Module

NOTE:

This section applies only to Wireless (W-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.

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.

Configuring a Wireless Module (Continued)

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.

NOTE:

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.

Wireless Configuration Overview

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.

The detailed configuration instructions that follow are for Windows XP. The basic instructions for Windows 2000 are the same. If you have any questions, please contact Sealevel technical support at support@sealevel.com

SeaI/O User Manual

Configuring a Wireless Module (Continued)

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 using the steps described at the beginning of this section. Depending on the country used, it may take several reset cycles to get the unit back to a channel valid for your region. Use the Wireless Configuration window to change channels, if possible.

The Key Encoding method can be either a Passphrase or a Hexadecimal Key, if using a WEP variant. If you are using a WPA variant, then the Key Encoding method is Passphrase.

Different security encryption methods require different Network Key types and lengths. The different key types and lengths are displayed below:

WEP 64-bit 10 character hexadecimal key or up to 32 character passphrase WEP 128-bit 26 character hexadecimal key or up to 32 character passphrase WPA up to 64 character passphrase WPA2 up to 64 character passphrase

D/A Settings

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.

A/D 10X Gain

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.

A/D and Current Loop Dipswitches

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

Wiring Options

SeaI/O Pass-Through Connector

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 (item# KT122) that includes four metal straps, four #4-40 screws, and a 5” RJ45 RS-485 interconnect cable (item# 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 RS-485 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 & 5).

NOTE:

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.

The SeaI/O-470 modules provide eight open-collector digital outputs. The outputs do not source any current and must be connected to an external power source, max 30VDC. The outputs act as a switch and the circuit is open until energized. When the output circuit is energized in software, the output sinks the current to ground, closing the circuit.

I/O Wiring – SeaI/O-520 Modules

Optically isolated inputs are arranged such that each group of two shares a single common. The four I/O points and shared common are connected via a six-position removable screw terminal. Input voltage range is 5-30VDC. Like the inputs, each group of two Form C relays also shares a single common. The NC and NO contacts of each relay along with the commons are brought out via a six-position removable screw terminal.

SeaI/O (RS-232) S-Series Modules

SeaI/O S-Series (RS-232) modules have an RJ45 connector on the face of the enclosure. Each S-series module includes a kit (item# 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 (item# DB109) with RS-232 pin out and a standard 7' CAT5 patch cable (item# 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.

NOTE:

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 Item# 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.

SeaI/O Mounting Kit

Expanding your I/O count is as simple as adding N-Series expansion units to the Base SeaI/O module (or other N-series modules). Each NSeries module includes an expansion and strap kit (Item# KT122), which includes a 5” CAT5 interconnect cable, four metal straps, and four #440 metal screws. The image shows a SeaI/O stack configuration using the expansion kit.

DIN Rail Mounting

All SeaI/O modules are available with a factoryinstalled DIN-rail mounting clip. Alternatively DIN-rail mounting clips can be ordered as a field upgrade kit (Item# DR104). The bracket with clip is easily attached using two included #4-40 Phillips head machine screws.

Table/Wall Mounting

The flush mount bracket kit (Item# KT123) is extremely versatile and can be used to mount SeaI/O modules from the top, bottom, or back edge. Individual modules or a stack of SeaI/O modules can be mounted flat to a tabletop, underneath a counter, or inside an enclosure. The kit can be used to mount SeaI/O modules flat to a wall, or along the back edge, similar to DIN-rail mounting options.

Universal Mounting Bracket

The universal mounting bracket (Item# KT125) can be used as a “backpack” to mount power supplies and other devices to SeaI/O modules. The bracket has holes for both 75mm and 100mm VESA mounting options. The universal arrangement of slots and holes accept bolt sizes to M4 and can be used for virtually any mounting configuration.

SeaLATCH™ USB

SeaI/O USB modules integrate a patent-pending SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable (Item# CA356) with a SeaLATCH USB type 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.

Examples of the isolated 7-port USB hub (Item# SeaI/O-270U) with SeaLATCH equipped Sealevel I/O devices are shown below.
