A8911-23 Firmware Update - Leviton A8911 Manuel D'installation Et D'utilisation

9 A8911-23 FIRMWARE UPDATE

From time to time, Leviton may release firmware updates with additional features and system changes.
To find out what firmware your A8911-23 has installed, read the firmware version register with a Modbus
utility, or use the "Advanced configuration" page in the AcquiSuite setup menu. Firmware update files may
be obtained from Leviton technical support.
The firmware update process requires an RS232 serial port and a windows computer to run the firmware
update utility. Before starting this process, verify your computer has a serial port available. You may need to
deactivate other software such as the palm pilot utility or ups monitor software. USB connected serial ports
may be used, however these are not as fast or reliable as standard computer serial ports and may fail to
upgrade the firmware correctly.
To update the firmware, use the following procedure.
1.
Install the Philips LPC2000 software as provided by Leviton.
2.
Remove power and DC load current from the A8911-23. Power can be disconnected by removing the
+24V wire from the screw terminal from the A8911-23 power connection.
WARNING: Disconnect power and lock-out all power sources during installation. DO NOT
CONNECT RS232 PORT WITH CURRENT INPUTS LIVE
3.
Remove the plastic lid from the A8911-23 module. The plastic lid is held in place with two plastic clips,
one on each side.
4.
Attach the A8911-23 to your computer with an RS232 serial cable. The A8911-23 programming
connector is the 9 pin RS232 connector on the top of the device.
5.
Power up the power supply to the A8911-23. The Green Alive LED should light up and blink.
