Why are there switches on UltraBlocks?

The switches provide two main functions:

1) Allow UltraBlocks to be field-switched between read-only and read-write operation. 

2) Allow end users to set the bridge's configuration for optimal use with their equipment.

Versatile Operation

In Write Protect mode, the UltraBlock will prevent ANY and ALL writes from reaching the attached device. It is compatible with any O/S that supports IEEE 1394 and has a compliant card and drivers.

In Read/Write mode (non-Write Protected), it can be used to attach a drive to be used for receiving images.

The black UltraBlock is shipped by default in a Read-Only (write blocking) configuration. However, they can be configured to enable Read-Write operation as well. The yellow UltraBlock, when available for purchase, is pre-configured for Read/Write (non-Write Protected) operation.

SWITCH 1
OFF = Read Only (write blocking enabled)
ON = Read/Write

SWITCH 2
OFF = Unit reports errors if writes are attempted
ON = Unit suppresses errors if writes are attempted

SWITCH 3
OFF = Unit reports Write-Protect (WP) status in code page
ON = Unit suppresses Write-Protect (WP) status in code page

SWITCH 4
Reserved
