1. GENERAL INFORMATION
1.1 About this manual
The Lambda SC is a system designed to control and drive a single SMARTSHUTTER. The
configuration and control of the Lambda SC is made via the USB port, and basic control is
possible via TTL triggering.
Refer to the REMOTE CONTROL section for instructions on how the USB connection to a
computer is made, how the USB device driver is installed. The next section also describes
the installation and running of a demo program that can be used to test the Lambda SC’s
USB connection, and to configure controller’s
SMART SHUTTER settings.
1.2 Technical Support
Unlimited technical support is provided by Sutter Instrument Company at no charge to our
customers. Our technical support staff is available between the hours of 8:00 AM and 5:00
PM (Pacific Time) at [phone]. You may also E-mail your queries to [e-mail].
2. SAFETY WARNING
To prevent fire or shock hazard do not expose the unit to rain or moisture.
To avoid electrical shock and exposure to hazardous electrical voltages:
Do not disassemble the unit. Refer servicing to qualified personnel.
Always use the grounded power supply cord set provided to connect the unit to a
grounded outlet (3-prong). This is required to protect you from injury in the event that
an electrical hazard develops.
3. PRECAUTIONS
3.1 On operation
Failure to comply with any of the following precautions may damage this device.
Operate the Lambda SC using 110V a.c., 60Hz or 220V a.c., 50 Hz line voltage.
The Lambda SC is designed for operation in a laboratory environment (pollution degree
I).
The Lambda SC is designed for connection to a standard laboratory power outlet
(overvoltage category II).
Operate only in a location where there is a free flow of fresh air on all sides. NEVER
ALLOW THE FREE FLOW OF AIR TO BE RESTRICTED.

Do not disconnect the cables between the controller and the mechanical units while
power is on. Please allow at least 20 seconds after turning the unit off before
disconnecting the mechanical units. Failure to do this may result in damage to the
electronics.
Since the Lambda SC is a microprocessor-controlled device, it should be accorded the
same system wiring precautions as any 'computer type' system. If microprocessor-based
systems in the lab require line surge protection for proper operation, then the same
protection should be provided for the Lambda SC.
3.2 On use of high-intensity light sources
Failure to comply with any of the following precautions may result in injury to the users of
this device as well as those working in the general area near the device.
Never look into the optical pathway of the high intensity light sources typically used with
this instrument. Doing so can cause permanent eye damage.
The high-intensity light sources typically used with this instrument also produce a
significant amount of heat. Direct contact with the housing of those instruments can
cause serious burns.
4. REMOTE CONTROL
The remote control of the Lambda SC can be achieved by issuing commands on a remote
computer and transmitting them to the Lambda SC over a USB (Universal Serial Bus) or RS-
232 serial connection. This chapter provides a description of these commands and how they
are used. Limited remote control can also be achieved with a TTL connection, a description
for which is provided later in this manual.
The following table shows how remote commands are categorized.
Table 4-1. Remote control command categories
Category Description
Shutter commands These are commands used exclusively for controlling the SmartShutter.
Special commands These are commands for the general control of the Lambda SC controller,
and are not specifically related to shutters.
Most of the commands described in this chapter are ones that are sent from the computer to
the Lambda SC. Some of these commands will cause the Lambda SC to return certain special
codes or one or more bytes of data. Some commands must be followed by one or more bytes
containing parameters. For each byte sent to the Lambda SC, that same byte is echoed
(transmitted) back to the remote computer as confirmation that the byte was received. This
echoing back of command bytes in no way indicates validation of a command or parameter,
but rather is an acknowledgement on the part of the controller that it has received the byte,
When the Lambda SC controller has finished performing the task associated with a command
(or command followed by one or more parameter bytes), the controller will transmit to the
host computer an ASCII carriage return (CR, 13 decimal, or 0D hexadecimal) as an indication
LAMBDA SC USB INSTALLATION & CONFIGURATION – REV. 1.03 (20080617)

7
that function associated with the command has completed and that the controller is now
ready for another command. This echoing back of bytes sent by the remote computer to the
controller, and the return of an ASCII carriage return after a command’s task is complete, is
the same for both serial and USB interfaces.
