Chapter 5 Remote Operation
This chapter is outlined as follows:
5.1 Selecting an Interface
5.2 USB & RS-232 Interface Operation
5.3 GPIB Interface operation
5.4 Data Format
The 5492B supports remote control over the USB (virtual com), RS-232, and GPIB interface located in
the rear panel. You can use only one interface at a time. Standard Commands for Programmable
Instruments (SCPI) is supported by these interfaces (unless otherwise noted), however they use
different hardware configurations and communication protocols.
5.1 Selecting an Interface
The 5492B supports the following interfaces for remote communication:
 USB (virtual COM) device interface
 RS-232 interface
 GPIB bus interface (optional) (model 5492BGPIB)
You can only use one interface at a time for remote communication. USB & RS232 interfaces are
selected as the default factory setting. You can select the interface from the front panel menu system.
The interface selection is stored in non-volatile memory and does not change from a power on/off or
instrument reset.
5.1.1 USB (Virtual COM) Interface
The USB device interface on this instrument is a USB virtual COM. After installing the appropriate USB
drivers, the instrument will be recognized and assigned to a COM port automatically by the PC as if it’s a
RS-232 serial interface. Aside from installing drivers, the setup and operation is the same as RS-232
serial interface, which is described in details in the following sections.
