Base Modules connect to the host via one of the following interfaces:
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 (Item number 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 pass-through connectors. For remote devices, separate power is required at each expansion unit.

Power Options
Base Module Power Connection
Base modules are powered from a 9-30VDC source using either the DC jack or screw terminals on the side of the unit. Sealevel offers several power supply choices to make connection easy (see Accessories chapter at the end of this document).
SeaI/O Expansion Power Connection
Each SeaI/O product, including the expansion modules, contains an onboard switching regulator power supply rated for 9-30VDC. For local installations (less than 10’ apart), expansion unit power is usually supplied from the Base unit via the pass-through connectors. The number of expansion modules that can be driven from the Base unit depends on the power source and number/type of expansion units. Refer to the chart below for power requirements. For expansion modules mounted remotely (greater than 10’ apart), separate power is required at each expansion unit.

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.

SeaI/O User Manual

Hardware Configuration

The SeaI/O-463 and SeaI/O-470 are the only two modules that require you to open the enclosure. On all SeaI/O modules, most device settings can be configured on the left side of the SeaI/O module. Refer to the SeaI/O Hardware Description section of this manual for a list of common features available and settings that can be changed on the left side of the SeaI/O module.
When connecting more than one SeaI/O module to a host computer, you will need to set the device address (Slave ID). This can be done in software or by using a rotary switch on the left side of the enclosure. Refer to the SeaMAX Application Suite section where you can find instructions for configuring the device address (Slave ID) and setting the termination pull up and pull down resistors.
SeaI/O-463 Ribbon Cable Installation Instructions
A copy of these instructions are included with the SeaI/O-463 module and can also be downloaded from the SeaI/O-463 product page on the Sealevel website.

SeaI/O-470 Jumper and Dipswitch Settings Instructions
The SeaI/O-470 module ships factory configured with the D/A outputs set for 0-10V 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 the power connected. Be sure to follow proper ESD procedures by grounding yourself and the SeaI/O module.
What you will need:
SeaI/O-470 module Phillips head screwdriver Slotted screwdriver
Step 1
Remove the terminal block from the left side and then remove the two black screws from each side of the module as shown in the image.
Step 2
On the front right side of the module, wedge a slotted screwdriver between the top and bottom halves as shown. Pry upwards – a pem in the top half must clear the metal lip in the bottom half of the enclosure.

SeaI/O 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 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 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:
Modules greater than ten feet apart must have separate power supplies. Refer to the Power Options section of this manual for recommendations.
