Return to Section 5 topics
CAUTION Delta, Pulse Delta, and Differential Conductance will not work if
the Model 2182/2182A is not using the default Trigger Link con-
figuration.
The hard-wired default configuration for the Trigger Link lines
of the Model 2182/2182A can be changed by qualified service

System connections for this configuration are shown in Figure 5-4.
RS-232 and Trigger Link – This system configuration uses the same RS-232 and
Trigger Link connections that are used for stand-alone operation. See “Connec-
tions – stand-alone system” for details on these system connections.
IEEE-488 or Ethernet (6221) – This system configuration uses a PC to communi-
cate with the Model 622x. For the Model 6220, the IEEE-488 bus interface can be
used. For the Model 6221, the IEEE-488 bus or the Ethernet can be used. For the
Ethernet, make sure to use a cross-over Ethernet cable for direct connection to
the PC.
