Remote digital I/O commands
Commands that control and access the digital I/O port are summarized in the following table. See the
TSP command reference (on page 11-1) for complete details on these commands. See the following
table for decimal and hexadecimal values used to control and access the digital I/O port and
individual lines. Use these commands to trigger the 2601B-PULSE using external trigger pulses
applied to the digital I/O port, or to provide trigger pulses to external devices.
Use these commands to perform basic steady-state digital I/O operations such as reading and writing
to individual I/O lines or reading and writing to the entire port.
The digital I/O lines can be used for both input and output. You must write a 1 to all digital I/O lines
that are to be used as inputs.
Remote digital I/O commands
Read one digital I/O input line
digio.writebit(bit, data)
Write data to one digital I/O output line
Write data to digital I/O port
digio.writeprotect = mask
Write protect mask to digital I/O port
Digital I/O programming example
The programming commands below illustrate how to set bit B1 of the digital I/O port high, and then
read the entire port value.
digio.trigger[1].mode = digio.TRIG_BYPASS
-- Set Bit B1 high.
digio.writebit(1,1)
-- Read digital I/O port.
data = digio.readport()
TSP-Link trigger lines
The 2601B-PULSE has three trigger lines that you can use for triggering, digital I/O, and to
synchronize multiple instruments on a TSP-Link
®
network.
