M2266S PCA Layout
M2266H PCA Layout

All configurations marked "*" are default settings

With respect to the setting below; - "short" means Jumper plug is set between specified pins - "open" means Jumper plug is removed from specified pins

Terminal CN3/CN9

Same settings are assigned on the same pins of both CN3 and CN9.

Set SCSI ID 9-10 11-12 13-14 ID OPEN OPEN OPEN 0 OPEN OPEN SHORT 1 OPEN SHORT OPEN 2 OPEN SHORT SHORT 3 SHORT OPEN OPEN 4 SHORT OPEN SHORT 5 SHORT SHORT OPEN 6 SHORT* SHORT* SHORT* 7

NOTE :The drive is shipped from the factory with the SCSI ID set to 7. But the links are offset, this is done intentionally as it will enable the user to configure the drive with enough shorting straps for any ID. It must be remembered though that the host adapter normally takes ID 7 with all peripheral devices using IDs 0 through to 6 7-8 SHORT* Time monitoring is disabled OPEN Time monitoring is enabled 5-6 SHORT* Read-Ahead caching is enabled OPEN Read-Ahead caching is disabled 3-4 SHORT* reserved 1-2 SHORT* Normal operational mode OPEN Diagnostic mode
