After a system prompt appears, type in ipconfig and then hit
Enter. The current IP address of the computer should appear.
If the first three segments of that IP address are different
than the first three segments of the humidifier’s default IP
(192.168.1.xxx), you must change either your computer or
Vapor-logic4’s IP address such that they match each other.
Field wiring:
Communication connections
3. Change the IP address of your humidifier or computer if
necessary.
a. Change the IP address of the humidifier to match your
computer.
The most straightforward way to change the IP address of the
humidifier using Vapor-logic4 is to use the keypad/display.
Go to Setup/Communications/Network IP address on the
keypad/display and change the IP address such that the first
three segments of the computer’s settings match the network
address. Make sure the last digit of the IP address is different
between the humidifier and the computer. Cycle power of
Vapor-logic4 board for address change to take effect.
b. Change the IP address of your computer to match the
humidifier.
Changing the IP address of the computer being used will
likely require administrative privileges for your company’s
network. Please consult your IT department for this task.

Vapor-logic4 data can be backed up to a USB flash drive. The
backup file contains all information relative to the humidifier,
including firmware, user settings, model number, serial number,
and the configuration string.
Backup files use the serial number in the backup file name so that
the file is easily matched to a particular humidifier.
To create a backup file:
1. Insert a USB flash drive into the USB port on the Vapor-logic4
board.
2. Go to Diagnostics/USB backup-restore/Back up settings
3. Select Yes. The backup process is complete when LED-2 (see
Figure 61-1) illuminates.
To restore from a backup file:
1. Insert the USB flash drive with that humidifier’s backup file into
the USB port on the Vapor-logic4 board.

Important: Do not change the name of this folder.
3. Copy the unzipped folder (VL4_update) to the root directory of
a USB ash drive (do not place within another folder).
Important: If the USB ash drive already has a folder named
VL4_update, either delete the folder or rename it prior to saving the
latest update folder on the USB. Do not overwrite its contents.
4. Place the humidier system in Standby mode.
5. Insert the USB ash drive loaded with the rmware update
folder into the USB port on the Vapor-logic4 board.
6. Disconnect power to the Vapor-logic4 board.
