WARNING! - DO NOT ATTEMPT TO CHANGE SETTINGS OR OTHERWISE OPERATE THE DRYER REMOTELY
WITHOUT A FIRM UNDERSTANDING OF DRYER OPERATION. IMPROPER SETTINGS OR CONTROL MAY
RESULT IN DAMAGE TO DRYER COMPONENTS OR PHYSICAL INJURY.
The user’s panel includes an Ethernet and a Serial port which can be used for Modbus communications. The Ether-
net port can be used to access Modbus/TCP registers, as well as, the internal VNC servers across multiple dryers.
The Serial port can access Modbus RTU registers on a single dryer using either RS232 or RS422/485
hardware protocol.
VNC Server
The internal VNC server runs in the back ground by default. Any VNC Client may be used to access the dryer’s VNC
server via port 5900.
Excessive network trafc or network interference may cause the VNC server to intermittently shut down. Rebooting
the HMI via the Service menu or via Modbus register 40101 will restore the VNC Server after reboot.
Ethernet
The Ethernet port is pre-congured to acquire its network IP address and conguration from the network’s DHCP
server. Proper cabling and isolation techniques are required to prevent electrical noise from entering the system
through this port. Contact your local electrical parts distributer for assistance.
Serial Modbus Port
The serial port is located along the bottom edge of the HMI. This port supports full RS232, RS422, and RS485 hard-
ware protocols. This port is NOT isolated. Proper cabling and isolation techniques are required to prevent electrical
noise from entering the system through this port. Contact your local electrical parts distributer for assistance.
