Remote Interface Operations
DL-2060 supports two remote interfaces: the built-in USB and GPIB (G type only). With
GPIB, you will need a GPIB interface card. This chapter lists the SCPI (Standard
Commands for Programmable Instrument) commands available to control the
multimeter. For the first time to use SCPI, users would better to refer to Appendix B. for
SCPI reference.
4.1 Pass/Fail Output From USB Connector
The USB connector on the rear panel of DL-2060 is a type-B connector. When the USB
interface is
disabled (GPIB interface is selected), the internal pass and fail TTL output
signals (limit testing) will be connected to the USB connector.
The pass and fail signals are low true and indicate the Math Pass/Fail Limit Test result for
the
next reading to be output to the GPIB interface. The signals are active low for
approximately 2ms (

100
μ
sec) for each reading taken. Figure 2-17 shows the USB
connector (type-B).
