3. Of the three standard keyboard modes currently in use mode number 2 is the one used by the vast majority of PC CPUs It is also the default state of all 101 key and PS 2 keyboards Mode 1 is used primarily by certain PS 2 CPUs Mode 3 is used by RS 6000 CPUs some other UNIX based computers and certain specialized servers The ServSwitch Jr MP supports all three of these modes As it receives signals from one of the keyboards it sends them to the currently selected PC CPU by emulating a keyboard of the appropriate mode for that CPU as it receives signals for one of the keyboards from the currently selected or scanned CPU it sends them to that keyboard by emulating a CPU of the appropriate mode Most CPUs that use keyboard mode 1 or 3 send a mode command to the keyboard at power up to put the keyboard in the proper mode A ServSwitch Jr MP can use these commands to automatically detect each such CPU s keyboard mode when you turn on the CPU afterit has been cabled to the Switch However the Switch doesn t automatically save this value unless you send it a Keep Settings command it will forget the modes it has detected when it is powered down then default to each port s most recently saved setting when it s powered up again SERVSWITCH JR MP The ServSwitch Jr MP can t detect the CPU s keyboard mode if the CPU doesn t send mode commands most CPUs that use mode 2 fall into this category or if the CPU is already ON when y
