LASER SAFETY The following information is provided to comply with the rules imposed by international authorities and refers to the correct use of the DS4800 scanner. Standard Regulations This scanner utilizes a low-power laser diode. Although staring directly at the laser beam momentarily causes no known biological damage, avoid staring at the beam as one would with any very strong light source, such as the sun.
This product is intended to be installed by Qualified Personnel only. This accessory device is intended to be supplied by a UL Listed or CSA Certified Power Unit with «Class 2» or LPS power source, which supplies power directly to the scanner via the 25- pin connector.
HANDLING The DS4800 is designed to be used in an industrial environment and is built to withstand vibration and shock when correctly installed, however it is also a precision product and therefore before and during installation it must be handled correctly to avoid damage.

2 INTRODUCTION 2.1 PRODUCT DESCRIPTION The DS4800 laser scanner satisfies the most advanced needs of a wide range of users. It has been developed focusing on the realistic requirements of its target market. The outstanding result is an extremely compact, cost-effective and easy to use industrial scanner.
Fieldbus network. During the reader startup (reset or restart phase), all the LEDs blink for one second. On the back of the reader near the cable, the “POWER ON” LED indicates the laser scanner is correctly powered.
Page 30
All scanners are typically located far away from each other and they use a dedicated presence sensor. At the end of each reading phase, each scanner transmits its own data message to the host. Thanks to ID-NET™, data collection among readers is accomplished at a high speed without the need of an external multiplexing device.

Pass-through mode allows two or more devices to be connected to a single external serial interface. Each DS4800 transmits the messages received by the Auxiliary interface onto the Main interface. All messages will be passed through this chain to the host.

The Master passes all messages to the Host.
For a Master/Slave Synchronized layout the External Trigger signal is unique to the system; there is a single reading phase and a single message from the master scanner to the Host computer. It is not necessary to bring the External Trigger signal to all the scanners.
