Firmware Update

6

 

With the OSM/ESM it is possible to update the firmware via the serial port.

You can obtain information on the firmware updates for OSM/ESM on the Internet at http://www.siemens.de/automation/service&support

specifying the keyword "OSM Firmware".

To download the firmware you require a PC with Windows 95/98/NT and the Hyperterminal program available under Accessories. The download is explained below based on the dialogs displayed in Hyperterminal.

Preparations

Connect the serial port of your PC and the OSM/ESM with a normal null modem cable . Depending on the port of your PC that you select, you use a cable with a 9- pin or 25-pin sub-D female connector at the PC end and a 9-pin female connector at the OSM/ESM end.

The following table shows the pinning and the connections for both types of cable:
