HMI5000B Installation Guide
USB
A USB driver (included with the EZwarePlus software) must be installed
when downloading from the PC to the HMI via USB connection.
Caution: When connecting two powered devices via USB, a
difference in potential can exist between the ground reference on
each device. If there is a difference in ground potential (voltage),
making a connection via a USB cable can complete a ground
loop that may damage the HMI and PC. The Maple Systems
Micro USB Configuration Cable (P/N 7431-0119) is
recommended for connecting the HMI to the PC. The shield is
not connected between the two ends of the cable, which will
prevent a potentially damaging ground loop from occurring
between the devices. Please refer to Page 6 for proper wiring
instructions.
Note: The USB Host port is designed for data storage only. If
connecting a USB hard drive, power the drive with its own power
supply. Do not charge any device from the USB port.

Maintenance

Fusing Requirements
If the display does not come on within two seconds of power up, remove
power. An internal fuse will prevent damage if the polarity of the DC
power is incorrect. Check wiring to ensure proper connections and try to
power up again
Serial Port Connections
The following diagrams indicate the proper pin connections for the serial
ports of the HMI.
