External Control

Controlling the LAMBDA 10-B externally via
computer is accomplished by sending commands
between the computer and the equivalent
connector on the rear of the controller: RS-232
(Serial, 9-pin DSUB), or USB.
The RS-232 (Serial) Interface: RS-232-C,
minimal 3-wire (Ground, Transmit, & Receive),
9-pin D-Shell connector (labeled "RS-232" on the
rear panel of the controller.
The USB Interface: Controlling the externally
via computer is accomplished by sending
commands over the USB interface between the
computer and the USB connector on the rear
panel of the LAMBDA 10-B. The USB device
driver for Windows is downloadable from Sutter
Instrument's web site (www.sutter.com). The
device requires USB CDM (Combined Driver
Model) Version 2.10.00 or higher. The CDM
device driver consists of two device drivers: 1)
USB device driver, and 2) VCP (Virtual COM
Port) device driver. Install the USB device driver
first, followed by the VCP device driver. The
VCP device driver provides a serial RS-232 I/O
interface between a Windows application and the
device. Although the VCP device driver is
optional, its installation is recommended even if
it is not going to be used. Once installed, the
VCP can be enabled or disabled.
The CDM device driver package provides two I/O
methodologies over which communications with
the controller over USB can be conducted: 1)
. Commands for PC parallel port control of dedicated TTL line.

USB Direct (D2XX mode), or 2) Serial RS-232
asynchronous via the VCP device driver (VCP
mode). The first method requires that the VCP
device driver not be installed, or if installed, that
it be disabled. The second method requires that
the VCP be installed and enabled.
Virtual COM Port (VCP) Serial Port Settings:
The following table lists the required RS-232
serial settings for the COM port (COM3, COM5,
etc.) generated by the installation and enabling
of the VCP device driver.
The settings shown in the above table can be set
in the device driver's properties (via the Device
Manager if in Windows) and/or programmatically
in your application.
