SeaDAC User 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.

- 16 -

SeaDAC User Manual

Host PC Configuration Tab (cont.)

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 module, select “ETHERNET” from the “COM Port” dropdown box. When Ethernet is selected, MaxSSD searches for any SeaI/O Ethernet 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.

- 17 -

SeaDAC 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.

- 18 -

SeaDAC User Manual

SeaI/O Configuration Tab (cont.)

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.

- 19 -

SeaDAC User Manual

SeaI/O Configuration Tab (cont.)

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 note regarding SeaI/O Ethernet (E-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. Therefore, if you have an Ethernet 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. 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.

- 20 -

SeaDAC 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.

- 21 -

SeaDAC User Manual

Digital I/O Tab (cont.)

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

- 22 -

SeaDAC 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.

- 23 -

SeaDAC 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)

- 24 -

SeaDAC 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.

SeaDAC User Manual

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:

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

SeaDAC 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 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 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.

Troubleshooting Ethernet (E-series) SeaI/O Modules

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

All Ethernet SeaI/O (E-series) modules are shipped with DHCP enabled. If no DHCP server is available or the DHCP server cannot be reached, the Ethernet SeaI/O module will default to a random IP address in the range 169.254.0.1 to

169.254.255.254. 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

The Ethernet 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 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 Ethernet SeaI/O (E-series) module’s TCP/IP to RS-485 translation data rate independently of the SeaI/O module itself. Therefore, if you have an Ethernet 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.

Hardware Configuration

8227 – Jumper and Dipswitch Settings

The SeaDAC 8227 module ships factory configured with the D/A outputs set for 010V and current loop mode on the A/D inputs disabled. If you need to enable current loop mode or set the D/A outputs to 0-5V, you will need to open the enclosure and access the jumpers (shown on the next page).

NOTE:

Do not perform these instructions with USB or field wires connected. Be sure to follow proper ESD procedures by grounding yourself and the SeaDAC module.

What you will need:

 SeaDAC 8227 module  Phillips head screwdriver

Step 1

Turn the SeaDAC 8227 module upside down and remove the four black screws from the locations shown in the image.

Step 2

Holding the top and bottom halves of the SeaDAC module together, flip the module back over. Remove the top half of the enclosure and set to the side.

Jumpers and dipswitch locations are outlined in the image to the right and are shown in detail on the following page.

SeaDAC 8227 Jumper Locations

This detail image of the right side of the SeaDAC 8227 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.

SeaDAC User Manual

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 SeaDAC 8227.

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 SeaDAC 8227 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
