These units can be connected via USB, Ethernet or Serially to a workstation.
They can also be 'chained' together to create larger combinations for Inputs or Outputs.
Sealevel GPI/O devices for Windows 2000 or Windows XP
| The Sealevel GPI/O
devices allow one to use an expandable
GPI/O interface with DAD. The units can be mixed and matched with DAD.
These units can be connected via USB, Ethernet or Serially to a workstation. They can also be 'chained' together to create larger combinations for Inputs or Outputs.
|
|
 |
Use of these devices is supported in DAD version 8.0.a. |
Installing the Sealevel Driver
|
One must first install the driver for the Sealevel GPI/O device. Select the model of the device via the pull-down menu and allow the device to install. Once the device has been installed one can plug the device in.
|
 |
|
|
If multiple units are to be chained together, one
must set each device to a unique address. This can be done via Software of via
the small rotary ADDR switch on the side of the unit.
Administrators should consult the manual for their respective units for the specific details on how to chain multiple units together. Please refer to the Sealevel Manuals for ALL specific details on proper physical connections. |
Configuring USB Devices:
|
For USB devices, Windows should detect the device and be allowed to install the needed files. One would then use the Windows Device Manager to determine the virtual COM Port that has been created for the device. To find the port, select PORTS (COM & LPT) and look for an entry listed as: SeaIO USB Expansion Interface (COM#) The COM# listed will be the COM Port DAD will use to talk to the USB Device. One would enter the COM Port given into the REMOTE=SEALEVEL COM# line. |
 |
Configuring Ethernet Devices:
|
When using the Ethernet devices one will need to change the IP Address of the unit. The IP Address should match the same IP Address scheme that is in use by the DAD Network. To change the IP Address one would run the Ethernet Configuration Tool found under START > PROGRAMS > Sealevel SeaMAX. To find the unit, press Search for SeaIO Devices. This will query the network for any Sealevel Ethernet devices. Once found, select that device and press Recover Module. This will open a Module Reset screen. Here one must enter the MAC Address (which is also listed on the bottom of the unit) followed the the IP Address and Network Mask. Pressing Recover Module will attempt to connect and upload the new settings to that unit. Each unit should have it's own unique IP Address. One would then use the IP Address given to this unit in the DAD CFI line: REMOTE=SEALEVEL <IP ADDRESS> |
|
Configuration of DAD:
Start up DAD. After DAD has loaded, go to SETUP and select CFI & README. Open the workstation’s CFI file.
Find the [EXTERNAL_DEVICES] section and edit the REMOTE= line:
| Type of Sealevel unit | REMOTE Line Value | Description |
| USB | REMOTE=SEALEVEL COMx | One would enter the COM Port
used by the Sealevel device.
DAD will communicate directly to the COM Port listed. One does not need to configure a COM Port in DAD. For example: SEALEVEL COM3 |
| Ethernet | REMOTE=SEALEVEL <IP Address> | One would enter the IP Address
of the Ethernet based Sealevel unit. Each unit must be given an unique IP
Address. Only one workstation can communicate to specific device at a time
and Devices cannot be 'shared' with other workstations.
For example: SEALEVEL 10.66.66.98 |
No other lines in the CFI need to be edited.
Save the changes and close the file. Hit the yellow REFRESH Button, then EXIT DAD.
After the CFI has been edited one must create a SeaMAX.INI file in the \DAD\FILES directory on the server.
The SeaMAX.INI file will contain the unit's model number along with details such as the total number of Inputs and Outputs.
The following is an example of a valid INI file.
[410]
Number of inputs = 16
Number of outputs = 16
[430]
Number of inputs = 32
Number of outputs = 0
Only one SeaMAX.INI file is needed. If one has many different units that will be attached to different workstation, this one file would contain all of the models used. DAD will use this file to determine the number of Inputs and Outputs. This file is shared by all workstations.
Once DAD has exited, one can restart the DAD Application.
I/O Wiring – SeaI/O-410, 420, 430, 440, and 450 Modules
|
Optically isolated inputs are arranged such that each group of four shares a single common. The four I/O points and shared common are connected via a five-position removable screw terminal. Input voltage range is 5-24 VDC. Like the inputs, each group of four Reed relays also shares a single common and connects via a five position removable screw terminal. Form C Relay outputs are arranged such that each group of two relays shares a common. The NC and NO contacts of each relay along with the common are brought out via a five-position removable screw terminal.
