Table 19 - RS-232C Settings
The RS-232 interface does not support hardware flow control (only transmit, receive,
and ground pins are used). The programmer should be aware of this limitation and
notice the command process time of the LCR meter. If the remote commands are
sent too fast to the LCR meter, the internal buffer may overrun and cause a
communication error. Therefore, adding a delay between commands may be
necessary to allow time for the meter to process.
USB (USBCDC - Virtual COM )
The standard USB port is a virtual COM port that can be used for remote communication. There
are no settings in the menu system for USB configuration. The settings are the same as the
settings for RS-232.

USBTMC
USB The standard USB port is a USBTMC-compliant port that can be used for remote
communication. There are no additional settings in the menu system for USB configuration. The
only requirement is that the USBTMC driver be installed. It is included when a VISA software is
installed on the computer. (We recommend using NI-VISA, which can be downloaded at
http://www.ni.com/visa/).
LAN (Ethernet)
The 894/895 can also be controlled via LAN interface. Refer to 8.1, LAN Setup for more
information.
