Connecting the Interface
3.3 Connecting the Interface
WARNING
• To avoid equipment failure, do not disconnect the communications cable while
communications are in progress.
• Use a common ground for both the device and the PC. Using different ground circuits
will result in a potential difference between the device’s ground and the PC’s ground.
If the communications cable is connected while such a potential difference exists, it
may result in equipment malfunction or failure.
• Before connecting or disconnecting any communications cable, always turn off the
device and the PC. Failure to do so could result in equipment malfunction or damage.
• After connecting the communications cable, tighten the screws on the connector securely.
Failure to secure the connector could result in equipment malfunction or damage.
CAUTION
To avoid damage to the device, do not short-circuit the terminal and do not input voltage to the
terminal.
