7: TSP command reference Series 2600B System SourceMeter® Instrument
7-398 2600BS-901-01 Rev. C / August 2016
Details
The binary representation of data indicates the output pattern that is written to the I/O port. For
example, a data value of 2 has a binary equivalent of 010. Line 2 is set high (1), and the other two
lines are set low (0).
Write-protected lines are not changed.Write-protected lines are not changed.
The reset() function does not affect the present states of the trigger lines.
Use the tsplink.writebit() and tsplink.writeport() commands to control the output state
of the synchronization line when trigger operation is set to tsplink.TRIG_BYPASS.Use the
tsplink.writebit() and tsplink.writeport() commands to control the output state of the
synchronization line when trigger operation is set to tsplink.TRIG_BYPASS.
Example
Sets the synchronization lines 1 and 2 high (binary 011).

tsplink.writeprotect
This attribute contains the write-protect mask that protects bits from changes by the tsplink.writebit() and
tsplink.writeport() functions. This attribute is not available on the Models 2604B/2614B/2634B.

Usage
mask = tsplink.writeprotect
tsplink.writeprotect = mask
An integer that specifies the value of the bit pattern for write-protect; set bits to 1 to
write-protect the corresponding TSP-Link trigger line
Details
The binary equivalent of mask indicates the mask to be set for the TSP-Link trigger line. For example,
a mask value of 5 has a binary equivalent of 101. This mask write-protects TSP-Link trigger lines 1
and 3.
Example
Write-protects TSP-Link trigger lines 1 and 3.
