Astra 1200S with an external power supply require Firmware 3.1. Installing the driver for a USB scanner under Windows 2000 please use the Updater VS355UP.EXE (913 KB). Should you experience any problems (error 31) while scanning under Windows 2000, please use this file pv8630.sys to replace the existing ones in folders "WinNTsystem32" and "WinNTsystem". Vistascan 3.55 and newer do not automatically install the driver for the Umax ISA SCSI controller UDS-IS11 SCSI-ISA ds_is.zip! To use the Umax USD-IS11 ISA SCSI controller under Windows ME you have to install the mini-port driver with the help of the Hardware-Assistant. In the hardware type list select "SCSI-Controller" and refer the Assistant to the folder Disk1 of the driver directory. The Installation of VistaScan under Windows 2000 does not directly support the Umax ISA-SCSI UDS-IS11 controller. If you use this controller, please install the driver DTC3X8X.SYS At the prompt for the address setting select 340h. Please consider that the ISA controller uses as default the address 340h, which cannnot be changed. Very often this address is used by network adapters and other ISA cards which can lead to hardware conflicts. Should this be the case, chande the address of the other adapter.
