ETH-1000 Chillgard LC Quick Start Guide for BACnet
MS/TP
This document provides a brief overview of the connections and settings that must be used to connect a
preconfigured ETH-1000 gateway to a MSA Chillgard LC Refrigerant Monitor. This document also contains the
BACnet object mapping for the application and some troubleshooting tips. For more information, please refer to
the ETH-1000 User’s Manual available at http://www.iccdesigns.com/products/millennium/eth-1000.html.
Wiring
Power Supply Wiring
A 7 – 24V DC power supply must be connected to the gateway’s terminal block at terminals TB:5 (POWER) and
TB:6 (GND) as highlighted in Figure 2.

Wiring the Gateway to the Chillgard LC
Connect the “RS-485 To Sensor Module” terminals −, +, and G on the Chillgard LC to the gateway’s terminal
block at terminals TB:2 (B), TB:1 (A), and TB:6 (GND) as shown in Figure 2. This terminal block on the Chillgard
LC will have wires for both the gateway and any sensors connected to it. Additionally, a jumper wire must be
placed on the gateway’s terminal block between terminals TB:1 (A) and TB:3 (Y). Another jumper wire must be
placed between terminals TB:2 (B) and TB:4 (Z). as shown in Figure 2.

Customizing the ETH-1000’s Configuration
The ETH-1000 can be configured via USB using the ICC Configuration Studio. Certain network settings and
BACnet settings may need to be modified to match a specific network configuration. To modify the gateway’s
configuration, open the ICC Configuration Studio and connect the gateway via the included USB cable. The
software will automatically recognize the connected device and upload the current configuration file stored on the
gateway. The configuration must be downloaded back to the gateway after making any changes. The latest ICC
Configuration Studio is available at http://www.iccdesigns.com/icc-configuration-studio.html.
Ethernet Network Settings
The network settings may need to be modified to be compatible with your network. These settings can be
modified in the ICC Configuration Studio by selecting “Ethernet” in the Project Pane and changing the settings in
the Settings Pane as shown in Figure 3.
Figure 3: Network Settings
BACnet Communications Settings
The UDP Port, Device Name, and Device Instance may need to be modified to be compatible with your network.
These settings can be modified in the ICC Configuration Studio by selecting the corresponding items in the
Project Pane and changing the settings in the Settings Pane. The UDP Port can be changed by selecting
“BACnet/IP Server” and entering the desired UDP port number in the UDP Port field as shown in Figure 4. The
Device Name and Instance can be changed by selecting “Device Object” and entering a value in the Device
Name and Instance Number fields as shown in Figure 5. The default settings for the gateway are shown in Error!

Troubleshooting
This section details some troubleshooting tips to follow if any issues are encountered when installing the gateway
and Chillgard LC onto a BACnet MS/TP network.
1. Power
a. Confirm that the gateway is receiving power from the 7 - 24V DC supply. The MS (Module Status)
LED should light green when the gateway is powered.
2. Wiring
a. Confirm the wiring matches the connections shown in Figure 2.
3. Configuration
a. Confirm that the gateway is configured with the appropriate network parameters (baud rate, MAC
address, device instance, etc) using the ICC Configuration Studio as described in the
Customizing the ETH-1000’s Configuration section.
4. Gateway LEDs
a. The MS (Module Status) LED should light green when the gateway is powered and should flash
green when the gateway is connected via USB.
i. If this is not observed, check the gateway’s power.
b. The RS-485 RX LED should flash red. The TX LED will always be off.
i. If this is not observed, check the wiring between the gateway and the Chillgard LC.
ii. Check the gateway’s configuration using the ICC Configuration Studio and confirm that
the RS-485 port is configured for Modbus Sniffer.
5. Chillgard LC Data Confirmation
a. View the gateway’s internal database via the Database pane in ICC Configuration Studio and
select the 16-bit Unsigned data type from the dropdown. There should be some highlighted cells
which do not show a value of 0.
6. BACnet Data Confirmation
a. View the gateway’s internal database via the Database pane in ICC Configuration Studio and
select the 16-bit Unsigned data type from the dropdown. The data shown in the highlighted cells
should match the data read on the BACnet system. The specific BACnet object mapped at an
address is shown when the mouse is hovered over a cell in the Database Pane.
