Cooling Group
Once each cooling unit has been connected through the A-Link Controller Area Network (CAN) bus, the individual units can share setpoints and temperature data.
See “Cooling Group Configuration” in the InRow RC Operation and Maintenance Manual for details on setting up the cooling group on the display interface.
Network Management Card to Customer LAN
Connect the cooling unit to the customer LAN using the RJ-45 port on the dis interface connection box.
See “Network Configuration” in the InRow RC Operation and Maintenance Manual for instructions on setting up the IP address and other network settings.
Network Management Card to StruxureWare™ for Data Centers
If the cooling unit and StruxureWare are connected to the same network, StruxureWare will auto-detect the cooling unit. It is critical that the cooling unit given a unique name at either the display interface or through one of the inter-enabled by the Network Management Card for easy identification in StruxureWare. A secondary method is to identify the unit by its IP address.
Unit to Customer BMS
The cooling unit can be monitored and controlled by a building management system (BMS) using the Modbus protocol. Connect the cooling unit to your BMS using the RS-485 connector on the cooling controller.
See "Modbus" in "Electrical Connections" in the InRow RC Installation Manual for instructions on wiring the RS-485 bus to the unit.
See "Configure Modbus" in the InRow RC Operation and Maintenance Manual for instructions on how to set the unit to work with a BMS.

Updating the Firmware
Item Description
4.3-in. touch-screen color display.
The cooling unit is powered when the LED is illuminated.
Unit firmware is updating when LED is blinking.
When this LED is illuminated, a new entry has been made to the event log.
4 Displays current alarm condition of unit.
5 Displays current network management card status.
6 Displays current network link status.
7 Resets the display microprocessor. This has no effect on the air conditioner controller.
8 Memory card expansion slot.
USB-B port used only by service personnel.
10 Supports firmware upgrades.
Connects the display to a local computer to configure initial network settings or access the command line interface (CLI).
Overview
Use a USB drive to transfer and upgrade the firmware files. The following provid an overview of steps required to update the firmware:
- Check the USB drive format.
- Create a firmware folder on the USB drive.
- Insert a USB drive in the USB-A port.
- Reset the display.
-
Wait until transfer is complete and remove the drive.
-
Download the firmware package and extract those files to the firmware folder.
-
Create an .rcf file for file transfer and place that file in the firmware folder.
Updating Procedure
- Insert the USB drive into an available port on the PC and verify that the first system is formatted as FAT32. If the drive is not formatted, the USB drive must be formatted prior before continuing.
- Create a new folder named "apcfirm" on the USB drive.
-
Obtain the firmware files from the local support team or service website. Unzip and extract the firmware files to the "apcfirm" folder. Typically there a three .bin files for the application:
-
(_acrc2g_)
- operating system (_aos_)
- boot monitor (_bootmon_)
- Use a text editor, for example Notepad, to create a file named upload.rcf.
- Edit the file upload.rcf and write a text string for each firmware module that you want to transfer. For example, to transfer the files shown in Step 3 type the following exactly as shown below:
IMPORTANT: The firmware modules must be listed in the proper order in the upload.rcf file.
• BM (bootmon) must be listed first.
- AOS (operating system) must be listed second.
- APP (application) must be listed third.
- Save the upload.rcf file in the "apcfirm" folder on the USB flash drive. The "apcfirm" folder should look similar to the following example:
-
Insert the USB drive into the display USB-A port. The display will detect that USB device has been connected.
-
Once acknowledged, press the Display Reset button. Wait approximately 2 - 3 minutes for the display to resume operation.
-
Return to the HOME screen menu.
NOTE: The touch screen will be disabled during the transfer process. There is no loss of cooling operation during the transfer process.
- Once the transfer is complete, remove the USB drive from the display. To perform the transfer on additional cooling units, insert the device in the USB-port and repeat Step 7.
Generating Service Passcodes
Generate service passcodes using the Cooling Tuner graphic user interface.
- Open the Cooling Tuner in the online or off-line mode.
- Select Maintenance > Service Authenticator.
- Enter the Product Key in the box using upper case letters.
- Click Generate. The service code generates.
- Enter the service code exactly as shown on the cooling unit display interface
NOTE: After 48 hours, a new service code is necessary to access the service menu.
Dew Point Control Pump Programming
