Section 1: Front and Rear Panel Operation
3. IEEE-488
Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as the Keithley Instruments
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 a PC.
8. TSP-Link
Expansion interface that allows a Series 2600A 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 240V AC at line frequencies of 50 Hz or 60 Hz. See the Series 2600A Reference Manual for
line fuse replacement instructions.
10. LAN
Use this RJ-45 connector to connect the instrument to the local area network. The RJ-45 connector
connects a network card, a network switch, a router or a hub. When connecting directly to a PC, a
crossover cable (included) must be used. When connecting to a network switch, router, or hub, a normal
CAT-5 cable (not provided) should be used unless your equipment has Auto-MDIX capabilities. If it does
have Auto-MDIX, the crossover cables may be used.
