Specifications
4. GENERAL
Host interfaces:
Computer control interfaces.
IEEE-488:
IEEE-488.1 compliant. Supports IEEE-488.2 common commands and status model topology.
RS-232:
Baud rates from 300 bps to 115200 bps. Programmable number of data bits, parity type, and flow control
(RTS/CTS hardware or none). When not programmed as the active host interface, the SourceMeter can use the
RS-232 interface to control other instrumentation.
Expansion interface:
The TSP-Link expansion interface allows TSP-enabled instruments to trigger and
communicate with each other.
Cable type:
Category 5e or higher LAN crossover cable.
Length:
3 meters maximum between each TSP-enabled instrument.
Digital I/O interface (see Models 2601 and 2602 GENERAL specifications for circuit diagram):
Connector:
25-pin female D.
Input/output pins:
14 open drain I/O bits.
Absolute maximum input voltage:
5.25V.
Absolute minimum input voltage:
–0.25V.
Maximum logic low input voltage:
0.7V, +850

A max.
Minimum logic high input voltage:
2.1V, +570

Maximum source current (flowing out of digital I/O bit):

ȝ
A.
Maximum sink current at maximum logic low voltage (0.7V):
–5.0mA.
Absolute maximum sink current (flowing into digital I/O pin):
–11mA.
5V Power supply pin:
Limited to 600mA, solid state fuse protected.
Safety interlock pin:
Active high input. >3.4V at 24mA (absolute maximum of 6V) must be externally applied to
this pin to ensure 200V operation. This signal is pulled down to chassis ground with a 10k
resistor. 200V
operation will be blocked when the INTERLOCK signal is <0.4V (absolute minimum of –0.4V). See figure below:
