CA356)
The CA356 is a USB device cable with a SeaLATCH USB type B
connector and standard USB type A connector. The metal
thumbscrew on the type B connector provides a secure metal-
to-metal connection to devices with SeaLATCH USB ports. This
72 inch cable is included with all Sealevel USB products with an
integrated SeaLATCH USB type B port. SeaLATCH USB cables
are fully interchangeable with standard USB cables.
M Series (RS-485)
No cable is included. Use twisted-pair wiring connected to RS-
485 signals via screw terminals on left side of SeaI/O module.
S Series (RS-232)
SeaI/O DB9 Female to RJ45 Adapter (RS-232 Pinout) and
CAT5 7' Patch Cable (Blue) (Part# KT119)
The KT119 includes a modular adapter with a DB9 female
connector that plugs directly into any standard DB9 RS-232
serial port and converts it to an RJ45 connection. Designed to
easily connect SeaI/O RS-232 devices to any standard serial
port via standard CAT5 patch cables. The KT119 ships with one
DB9 female to RJ45 adapter, Item # DB109, and a 7' CAT5 patch
cable, Item # CA246.
N Series (Expansion)
Expansion and Strap Kit - for SeaI/O
(Part# KT122)
Included with all N-series expansion modules, the KT122
expansion and strap kit has four metal straps, four #4-40
screws, and a CA239 RS-485 interconnect cable. The metal
straps allow you to connect a Relio R1100 system and multiple
SeaI/O modules together in a stack. The CA239 interconnect
cable can be used to connect two SeaI/O modules together via
the RJ45 connectors. This provides an easy method to cascade
RS-485 signals, and power and ground from one module to the
next. When used in combination with the KT123 flush mount
bracket kit, the KT122 expansion and strap kit can be used to
mount a stack of SeaI/O modules, including a Relio R1100
system, in a variety of mounting positions and locations.
All Models
Each SeaI/O unit is shipped with 4 adhesive rubber feet that can
be attached to the bottom of the enclosure to enhance stability
in table mount applications.

Maximizing Performance
All SeaI/O modules have a default baud rate of 9600. If lower latencies are required, the baud rate can be
changed via the Sealevel utility, MaxSSD, included in your SeaMAX installation.
All items can be purchased from our website (www.sealevel.com) or by calling our sales team at +1
[phone].
To change the baud rate, connect to a SeaI/O module using MaxSSD. If you need to change the baud rate of
multiple devices, check the “Broadcast to Multiple Modules” box. Select the desired baud rate from the baud
rate dropdown and click “Set Settings.” If you are connected to the modules via a COM port, you will need to
reopen the COM port with the new baud rate.
Example timing values
SeaI/O-470
Baud rate: 9600
Reading 8 Digital Inputs Average Time: 32.00ms
Writing 8 Digital Outputs -- OFF state Average Time: 32.00ms
Writing 8 Digital Outputs -- ON state Average Time: 32.00ms
Reading 16 Analog-to-Digital Converters Average Time: 48.01ms
Writing to 2 Digital-to-Analog Outputs Average Time: 32.00ms
SeaI/O-470
Baud rate: 115200
Reading 8 Digital Inputs Average Time: 15.57ms
Writing 8 Digital Outputs -- OFF state Average Time: 15.92ms
Writing 8 Digital Outputs -- ON state Average Time: 16.21ms
Reading 16 Analog-to-Digital Converters Average Time: 16.25ms
Writing to 2 Digital-to-Analog Outputs Average Time: 16.26ms
Higher baud rates are more susceptible to electrical line noise. If you find that you are receiving
erroneous results, try lowering the baud rate or shortening your cables.

SeaI/O Hardware Description
SeaI/O Base and Expansion Modules
Base Modules connect to the host via one of the following interfaces:
•Wireless Gateway –Wireless Modbus TCP
•W-Series –Wireless Modbus TCP
•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
(Part# 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. Refer to the Power Options
section of this manual for more information on SeaI/O power requirements and power supply sizing.
