What Display
Terminals Can Be
Used?
The Command Module has a 9-pin DTE RS-232 connector. You can
connect a terminal or PC to the Command Module using the RS-232
interface. Such connections can display the Command Module’s power-on
and configuration sequence, and function as a front panel to your VXIbus
C-Size system.
The Command Module’s RS-232 interface is factory-configured as shown
in the following table.
Baud Rate 9600 RecvPace Xon/Xoff
Parity None XmitPace Xon/Xoff

What are Interrupt
Lines?
In a VXIbus system, communication and coordination between a
commander and its servants is often achieved using the VXIbus backplane
interrupt lines. Such is the case with the Agilent E1406/05 Command
Module and Agilent Technologies’s register-based modules.
There are seven backplane interrupt lines. These lines are assigned to
devices by the resource manager during the system’s power-on sequence.
When a controller such as the Agilent V/382 or Agilent V743 is the
resource manager, it assigns line 1 to itself, and assigns lines 2 through 7 to
other interrupt handlers in the system. In systems containing an Agilent
V/382 or Agilent V743 (as resource manager) and an Agilent E1406/05
Command Module, the Agilent V/382 or Agilent V743 will assign the
Command Module interrupt line 2 - if the Command Module has the next
lowest logical address.
