Omron V680 Product Manual page 5

Seven maintenance modes make it easy to diagnose the communications conditions from the front
panel of the Controller or Amplifier Unit. The data can also be output from the USB port of the Controller
to a personal computer or other monitoring device.
(Maintenance Mode cannot be used with the V680-H01 or V680-CH.)
Communications Success Rate Measurement Mode
Confirms the communications success rate between the Read/Write Antenna and ID Tags.
A total of 100 communications are executed without retries, and the rate of communications success is
displayed in levels ranging from 01 to 99.

Host Device Communications Monitor Mode (Protocol Analyzer Function)
This mode can be used as a protocol analyzer function for host device communications lines.
The communications commands sent from the host device and the execution result responses can be output
from the USB port of the Controller.

Tag Communications Test Mode
Confirms communications ability between the Read/Write
Antenna and ID Tags.
The end codes are displayed to show the results of communications
between the Read/Write Antenna and ID Tags. When the Controller
is mounted inside a control panel, or in some other location, this
data can be output from the Controller's USB port and easily
checked on a monitor.
(The Tag Communications Test Mode uses only read operations.)
Host Device Communications Confirmation Mode
Confirms whether the signals sent from the Controller are being correctly transferred to an external device.
The communications commands and responses between the Controller and a host device are output from the
Controller's USB port for easy identification of problems, such as incorrect communications parameters or wiring.
