The integrated V680S-series Reader/Writers (V680S-HMD6@-ETN) perform communications with RF Tags
according to query from a host device.
Integrated Structure
The controller, amplifier, and antenna are integrated into the Reader/Writer for a simple structure.
Simple Installation
The Reader/Writer is automatically set to the best parameters according to the RF Tags to achieve
stable communications with more consistent communications and less omissions of RF Tags in the
communications field.

Product Overview
Stable Operation
When the Reader/Writer communicates with an RF Tag, it diagnoses the communications leeway and
reports the result. You can check the communications leeway to appropriately install the Reader/Writer
and RF Tags to achieve stable operation of your OMRON RFID System.
You can use communications leeway diagnosis with Reader/Writers with firmware version 2.00 or higher.
For details, refer to Using Communication Diagnostic and the RF Analyzer in Section 6 Functions.
p.129
If you use the RFID System under installation conditions that provide a high communications leeway,
you can reduce communications troubles during system operation and achieve stable line operation.

Note: If you start the Reader/Writer with the control signal connected to the -VDC side of the power supply, the Reader/Writer
will start in Safe Mode.
Insert the V680S-A41@M/-A51@M Cable into the connector on the Reader/Writer and turn the cable connector on
the Reader/Writer end clockwise to lock it in place.
Connect the RJ45 connector on the V680S-A41@M/-A51@M Cable to an Ethernet port on the host device.
* Connect the RJ45 connector to the Switching Hub when you use Switching Hub.

Setting Reader/Writer Communications Conditions
Change the network settings of the host device to match those of the Reader/Writer.
Host Device Setting Example
IP address: 192.168.1.100
Subnet mask: 255.255.255.0
he default network settings for the Reader/Writer are listed in the following table.
IP address192.168.1.200
Subnet mask255.255.255.0
Default gateway192.168.1.254
Port number502
Port number for Web browser7090
Start a Web browser (e.g., Internet Explorer) on the host computer, enter http://192.168.1.200/ in the address box, and press the
Enter Key. Communications will be possible if the following view appears.
