Duplex Unit Switch Settings
1, 2, 3... 1. CPU Usage Switches
These switches control the power supply to the left and right CPU Units.
In a duplex system, set both CPU Usage Switches to
"CPU USE." In a simplex system, set the desired CPU
Unit's Usage Switch to "CPU USE" and the other CPU
Unit's switch to "NO USE."
Power will be supplied to a CPU Unit when its CPU Usage Switch is set to
"CPU USE." Set the switch to "NO USE" when the CPU Unit isn't being used
or the CPU Unit is being replaced with the PC power on.
2. Duplex/Simplex Mode Switch
Set this switch to DPL to operate the PC as a duplex system; set it to SPL to
operate the PC as a simplex system.
DPL: Set to DPL for duplex operation.
SPL: Set to SPL for duplex operation.
This switch setting becomes effective when the power is turned on, a CPU
Usage Switch is switched from NO USE to CPU USE, or the Initialize Button
is pressed.
3. Active CPU Switch
In a duplex system, this switch determines whether the left or right CPU Unit
is the active CPU Unit. Select which CPU Unit is the active CPU when oper-
ating the PC in duplex mode.
ACT. LEFT: Sets the left CPU Unit as the active CPU Unit.
ACT. RIGHT: Sets the right CPU Unit as the active CPU Unit.
This switch setting becomes effective when the power is turned on or a CPU
Usage Switch is switched from NO USE to CPU USE. Setting changes dur-
ing operation are ignored.
4. Initialize Button
Initializes changes in duplex system operation. For example, press this but-
ton when you want to switch from simplex mode to duplex mode after replac-
ing a CPU Unit in which an error occurred.
