Downloading IOLAN Firmware

Downloading IOLAN Firmware

To upgrade the IOLAN firmware (software):

zIn DeviceManager, select Tools, Advanced, Download Firmware to IOLAN. You can browse to the firmware location. Once the firmware download is complete, you will be prompted to reboot the IOLAN. You can choose to reboot the IOLAN at another time by selecting Tools, Reset,

Reboot IOLAN.

zIn WebManager, under the Administration option, select Update Firmware. Either browse to the firmware file and then click the Upload button or configure the TFTP server and click the Upload button. Note: If you use the TFTP option, the specified TFTP server must be on the same subnet as the IOLAN.

Upgrading the firmware does not affect the IOLAN’s configuration file or downloaded custom files.

Calibrating I/O

All I/O channels are factory calibrated and should not need recalibration during initial use. However should calibration be required, you can recalibrate in DeviceManager or WebManager. In DeviceManager, you calibrate the I/O channel(s) by selecting Tools, I/O Channels, Calibrate. In WebManager, you calibrate the I/O channel(s) by selecting I/O Channels, Calibrate.

Calibrating Analog Input

To calibrate an Analog input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to voltage, you cannot calibrate it for current. The voltage range configured for this channel will also dictate what is being calibrated. For example, if this channel is configured for a range of +/-10V, calibrating this channel will calibrate all channels which are configured for +/-10V. During the calibration process, you will be asked to apply the minimum and maximum configured range value to the channel; for example, to calibrate for voltage +/- 10V, you will be prompted to first apply -10V and then +10V to the channel.

Also, you cannot actively calibrate disabled channels (although, for Voltage, if you enable the channel and then set it for a range that has already been calibrated for another channel, it will also be calibrated).

Calibrating Voltage

When calibrating the IOLAN Analog input for voltage, you will need a calibration meter that is better than .1% volts precision. When you calibrate one channel, all voltage channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are also automatically calibrated.

Calibrating Current

When calibrating the IOLAN Analog input for current, you will need a calibration meter that is better than .1% current precision. Each channel needs to be calibrated individually.
