Electrostatic Discharge
Precautions
Follow these ESD precautions when you handle this terminal:
• Touch a grounded object to discharge potential static.
• Use an anti-static wriststrap connected to the work surface.
• Use properly grounded tools and equipment.
• Avoid touching pins, leads, or circuitry.
• Always hold components with a printed circuit board (PCB) by its edges
and place it with the assembly side down.
Connect to USB Ports
Each terminal has one USB 2.0 (type A) host connection and one USB 2.0
(type B) device connection.
Icons identify the USB host connections. The USB host connection supports
0.5 A at 5V DC. Connected USB devices must not exceed this power load.
ATTENTION: Electrostatic discharge (ESD) can damage static-sensitive devices
or microcircuitry.
• Disconnect all power before you work on the terminal as detailed in Voltage
Precautions on page 87.
• Observe proper packaging and grounding techniques to help prevent damage.
IMPORTANT The USB host connection is intended for temporary use with USB drives during
deployment (user application file transfers) or maintenance (file transfers and
troubleshooting profiles). It can be used with an external hub, keyboard, and
mouse during runtime operations but it is not recommended for data logging
or user application runtime files.
