NOTE: The reset button restarts the server and resets all settings to factory defaults. Use a pointed
object such as a straightened paper clip to hold the reset button down for 5 sec. The RDY LED will
turn red as you are holding the reset button down. The factory defaults will be loaded once the RDY
LED turns green again. You may then release the reset button.

The following topics are covered:
Hardware Installation
¾Connecting the Power
¾Grounding the ioLogik R2140
¾Connecting to Analog Sensors and Devices
¾Setting the RS-485 Baudrate
¾Setting the RS-485 Unit ID
¾Modbus/RTU Devices
Software Installation

ioLogik R2140 User’s Manual Initial Setup
Hardware Installation
Connecting the Power
Connect the 12 to 48 VDC power line to the ioLogik R2140’s terminal block (TB1). If power is
properly supplied, the power LED will glow a solid red color until the system is ready
ATTENTION
Disconnect the power before installing and wiring.
Disconnect the power cord before installing and/or wiring your ioLogik R2140.
To protect your system, power up the ioLogik first, then the sensors.
When powering down, shut off power to the sensors first, then the ioLogik.
Do not exceed the maximum current for the wiring.
Determine the maximum possible current for each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current exceeds the maximum rating, the wiring could overheat, causing serious damage to
your equipment.
Grounding the ioLogik R2140
The ioLogik R2140 is equipped with two grounding points, one on the back wall-mounting plate and
the other on the DIN-rail attachment. Both grounding points are connected to the same conducting
pathway.

Analog Input
Setting the RS-485 Baudrate
The RS-485 port is used to communicate with other RS-485 devices or to link to another ioLogik
RS-485 I/O server. The RS-485 port can run Modbus/RTU or I/O command sets. The baudrate is set
by a physical dial on the back of the ioLogik R2140. The default settings are baudrate = 115200,
parity check = N, data bits = 8, and stop bit = 1.
Baudrate for RS-485
(parameters are N, 8, 1)
Dial setting and corresponding baudrate:
0:115200 1:57600 2:38400 3:19200
4:9600 5:4800 6:2400 7:1200
Setting the RS-485 Unit ID
The ioLogik R2140 needs to be assigned a unit ID in order to use the RS-485 bus. You may assign a
number from 1 to 31. Unit ID 0 is reserved for the first device on the RS-485 bus, such as a PC or
PLC.
Modbus/RTU Devices
The RS-485 port runs Modbus/RTU and can connect to any Modbus device. You may use different
methods to connect different combinations of ioLogik R2000 servers and other Modbus devices.
Some examples are shown below:
Connecting One Modbus/RTU Device

Software Installation
ioAdmin is a Windows utility that can connect to the ioLogik R2140 for configuration and
management. The ioLogik R2140 may also be configured through the optional LCM.
1. Install from the Document and Software CD: Insert the Document and Software CD into the
host computer. In the root directory of the CD, locate and run SETUP.EXE. The installation
program will guide you through the installation process and install the ioAdmin utility. You can
also install the MXIO DLL library or ioEventLog separately.
2. Open ioAdmin: After installation is finished, run ioAdmin from Start ÆProgram Files Æ
MOXAÆIO Server ÆUtility ÆioAdmin.
3. Search for the server: On the menu bar, select System ÆAuto Scan Remote I/O Server. In
the dialog window, select RS-232/485 I/O server and click Start Search.
If ioAdmin is unable to find the ioLogik R2140, there may be a problem with your COM port
settings. Click Port Settings to view or modify the settings.

4. Monitor I/O status: Once the unit is found by ioAdmin, you may view the status of all
attached I/O devices on ioAdmin’s main screen.
You may now use ioAdmin to setup or configure the unit.

ioLogik R2140 User’s Manual Using ioAdmin
Searching for the Unit
After opening ioAdmin, you will need to find your unit over the RS-485 connection. From the
pull-down menu, choose System - Auto Scan Remote I/O Server.
Select RS-232/485 I/O server and click Port Settings to set/verify the serial port settings.
When you click Start Search, ioAdmin will begin searching up to 99 ports for your ioLogik unit.
The timeout interval is for RS-485 communication and defaults to 2000 ms. As soon as your ioLogik
R2140 appears as shown below, you may click Stop. Otherwise, ioAdmin will continue to search all
99 ports.
ATTENTION
If ioAdmin is unable to find your ioLogik R2140, make sure that the baudrates match. Please
refer to Chapter 2 for setting or viewing the baudrate.
ATTENTION
Even if ioAdmin is unable to find your ioLogik R2140, you may still access the On-line Wiring
Guide. Please refer to the On-line Wiring Guide section for details.
