    Base modules are powered from a 9-30VDC source using either the DC jack, screw terminals or the Expansion pass-through connectors on the side of the unit. Sealevel offers several power supply choices to make connection easy (see the Accessories chapter at the end of this document).
  • Page 39 0.5W Sample Power Calculation A typical application for SeaI/O products would use one Base module and several N-series 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.

  • Page 42 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 Seallevel I/O modules are 9600 baud and no parity.
  • Page 43 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.
  • Page 44 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.
  • Page 45 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.

Converting A/D & D/A Values 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.

  • Page 93 To measure these devices the ground reference point must be connected to the analog ground reference of the SeaI/O-570 as shown in the above schematic. Without this connection, the signals will float, and an accurate measurement is not possible.
  • Page 94 A ground-referenced signal is a signal that is connected in some fashion to the building system ground and therefore is already connected to a common ground point with respect to the SeaI/O-570. Examples would be non-isolated outputs of instruments and devices that are connected to the same building power system as the SeaI/O-570.
  • Page 95 I/O Wiring – SeaI/O-580 Modules The 580E/580PoE optically isolated dry-contact inputs are arranged such that each input has a dedicated common terminal. The Common terminals are all connected to one isolated ground on board. Each dry contact (no-voltage) input detects a contact closure between two externally wired connections. Four (4) input/common pairs are connected via an eight-position removable screw terminal connector, and there are eight (8) connectors for a total of 32 inputs.
