1 CHANNEL A and CHANNEL B (Channel B on 2602/2612 only)
Input/output connections for source, sense, and guard.
2 DIGITAL I/O
Female DB-25 connector. 14 pins for digital input or output, one pin for Output Enable
(2601/2602) or Safety Interlock (2611/2612); +5V and GND pins are also provided.
Use a cable equipped with a male DB-25 connector (Keithley Instruments part number
CA-126-1CA).
3 IEEE-488
Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as the Model
7007-1 or Model 7007-2.
4 Cooling exhaust vent
Exhaust vent for internal cooling fan. Keep vent free of obstructions to prevent overheating.
5 Chassis ground
Ground screw for connections to chassis ground.
6 Low noise chassis ground
Ground jack for connecting Output HI or LO to chassis.
7 RS-232
Female DB-9 connector. For RS-232 operation, use a straight-through (not null modem)
DB-9 shielded cable (Keithley Instruments Model 7009-5) for connection to the PC.
8 TSP-Link
Expansion interface that allows a Series 2600 and other TSP-enabled instruments to
trigger and communicate with each other. Use a category 5e or higher LAN crossover
cable (Keithley Instruments part number CA-180-3A).
9 Power module
Contains the AC line receptacle and power line fuse. The instrument can operate on line
voltages of 100V to 240VAC at line frequencies of 50 or 60Hz.
