Event/Alarm Limit: Selects the high-limit numbers for events/alarms in 256, 512 or 1024.

LCD:

Screensaver: To prolong the life of the LCD display, it is suggested to set the display turn- off time in 1, 10, 20, 30, 40, 50 or 60 minutes after the recorder is operated. The recorder continues to read data while it is in the Screen Saving mode. The display turns on again by pressing any soft key. When an alarm occurs, it turns on the display as well. It was initially

set for 10 minutes for Screensaver from the factory.

IR detector: Enables the infrared technology on recorder is an innovative idea to prolong the lifetime of LCD display. The Infrared detector works with the Screensaver to protect the LCD. The Infrared detector senses the movement of body temperature when a user gets closer or walks away. (Range approximately 2 meters). Operation is as follows: Set the IR Sensor to On and Screensaver at 1 Min. Display will turnoff in 1 minute after the user walks away from the recorder. Once the Infrared detector senses heat movement within 2m of the recorder, display turns on straight away, without needing to press any key on the recorder.

Note:

IR( Infrared ) detector needs to work together with Screensaver, it cannot function alone. However, the Screensaver can function alone after the IR Sensor is disabled.

Communication

PCTransfer: Selects RS-232, RS-485, or standard Ethernet communication.

RS-232, RS-485:

Address: 0 to 31 nodes for RS-485

BaudRate: Selected from various Baud rates 1200, 2400, 4800, 9600, 19200 or 38400.

DataFormat: Selected from one of four data formats.

Ethernet:

IP: Select Automation if the server on the network automatically allocates the IP address for the recorder. Select User Define to manually set a fixed address for the recorder. Two columns will appear for keying in fixed addresses

IP Address: Defines the correct address of the recorder on the network

SubnetMask: Defines the correct SubnetMask address on the network

DefaultGateway: The Gateway IP address on Ethernet.

Note:

If Automation is selected, the IP address and SubnetMask are invisible. IP address can be found in 4.6 System Info mode under Configuration. Because IP address might be reallocated with new address by the server after power off and on, the user defining fixed addresses is recommended.
