Figure 5-3 System Connections – Stand-Alone Operation - Keithley 6220 DC User Manual

5-6 Delta, Pulse Delta, and Differential Conductance
Trigger Link – The Trigger Link synchronizes triggering between the Current
Source and the Nanovoltmeter. Trigger Link connections assume that the Model
2182/2182A is using the factory default (hard-wired) configuration:
EXT TRIG (input) = line #2
VMC (output) = line #1)
Delta, Pulse Delta, and Differential Conductance will not work if the
Model 2182/2182A is not using the default Trigger Link configuration. See
"Changing trigger link lines" in Section 5 (Disassembly) of the Model 2182/2182A
Service Manual.

System connections – stand-alone operation
Connections – PC control system
System connections for this configuration are shown in
RS-232 and Trigger Link – This system configuration uses the same RS-232 and
Trigger Link connections that are used for stand-alone operation.
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.
