Introduction
This Guide explains how to use the remote control interfaces of the SCHOTT Microscopy Light Source (MC-
LS). Please refer to the MC-LS Quick Start User Guide for more information. All technical information can be
downloaded by visiting https://www.schott.com and navigating to the MC-LS product page.
Remote Operation
Two connectors enable remote operation on the rear of the MC-LS, labeled USB and IN/OUT. The IN/OUT
port is a standard 9-pin D subminiature receptacle that combines RS232 signal lines with additional digital and
analog signals.
Figure 1 –Front Controls
Figure 2 –Rear Controls
USB Port
The USB port is a standard USB B receptacle that functions as a virtual COM port. In Windows, the port
enumerates with the name "Cypress USB UART." The serial commands are described in the Serial
Communication Protocol section.

USB Driver Installation
Windows drivers are available for download from the SCHOTT website. The driver package contains the
following files:
Install the drivers by running Driver Installer x64.exe for 64-bit Windows systems and Driver Installer x86.exe
for 32-bit Windows systems. The driver installation program may need to be run as an administrator, which is
typically done by right-clicking the file name and selecting "Run as administrator" from the context menu.
IN/OUT Port
The IN/OUT port contains an RS232 port for serial communication and discrete digital and analog signals for
basic remote control. The connector on the MC-LS is a standard female 9-pin D-Sub receptacle. The pinout is
described in Figure 3 and Table 1.

RS232 Signals
The RS232 interface uses three pins: 2 (Tx), 3 (Rx), and 5 (Common). The port is configured to operate at
9600 baud, 8 data bits, 1 stop bit, and no parity. The serial commands are described in the section Serial
Communication Protocol.

MC-LS Remote Operation Guide D20990.106 Rev A 5
NOTE: Some PC serial ports and USB-Serial converter cables have a low impedance connection
between Pins 1 and 5, which drives the digital input pin low, disabling the LED output when the serial
cable is plugged in. In this case, change the polarity of the digital input pin to "Low = LED on" using
the serial command "&J1". See section J –Digital Input Polarity. The setting change reverts to the
previous value when power is cycled. To save the setting, see section S –Save Settings.
Analog/Digital Control
Four pins are provided on the IN/OUT port for simple on/off control, intensity adjustment, and fault monitoring
using just a few external components. Refer to Figure 4 for an example circuit for a remote control application.
The digital input pin has an internal pull-up that causes the
input to be "high" when disconnected. Connecting the pin to
Common (pin 5) drives the input low ("active low").
When the pin is not active, the LED output turns on and off
as expected (e.g., when the front button is pressed or the
appropriate serial command is received). When the pin is
active (low by default), the LED output turns off regardless of
any other input.
The active state of the digital input can be reversed with the
J –Digital Input Polarity command. For example, if the "&J1"
command is sent, the LED turns off when the input pin is
high and operates normally when the pin is low.
Additionally, the functional behavior of the digital input can
be changed to accommodate different types of switches with
the JM –Digital Input Mode. For example, the digital input can be configured to turn on/off the LED with a
toggle or rocker switch, where the state of the output is dependent on whether the switch is opened or closed.
The digital input can also switch the LED on/off with a momentary pushbutton or footswitch where the LED
output toggles on or off with each switch press.
The J and JM commands allow for any type of switch to be used to enable or disable the light source, such as
a rocker switch or a pushbutton switch. Refer to the individual command descriptions for details.
Serial Communication Protocol
Remote communication with the MC-LS follows a command-response pattern. A command must be sent to
control the unit or query an operating parameter. Once received, the unit performs the requested action and
sends a response.
The unit accepts commands through the serial interfaces in the form of ASCII strings. Commands are used to
control (e.g., disable/enable the LED output, adjust intensity, change settings, etc.) or query the unit's
operational status (e.g., LED enabled/disabled, intensity, temperature, voltage, etc.).
Unless otherwise noted in the command descriptions below, configuration changes are not saved until the S –
Save Settings command is sent. On power-up, the MC-LS reverts to the last saved settings or the factory
default if no saved settings exist.

Command Structure
The structure of the string for a MC-LS serial command is organized as follows:
<Start><Command><Parameter><Terminator>
Position
Format
Description
<Start>
&
A command string always starts with the ampersand (&)
character. The parser ignores all characters until this character
is received, indicating the start of a command.
<Command>
1-3 letters
Consists of one, two, or three letters indicating the desired
command. The unit does not distinguish between upper and
lowercase characters; however, responses are always
lowercase.
<Parameter>
? or 1-5
alphanumeric
digits
If '?' follows the Command Mnemonic, the command is a query.
No other characters may follow the '?' except for the termination
character.
If a question mark does not immediately follow the command
mnemonic, the command is a parameter. Parameters are used
to change a setting or control the operation of the unit.
<Terminator>
Carriage
Return
The termination character ends the command or response. The
command string is processed once the termination character is
received.
The carriage return is ASCII code 13 (0x0D) and is denoted as
'\r' in many programming languages.
Responses
The MC-LS responds to input commands with a string of characters as described in the following sections. The
maximum length of the response is 64 characters (63 characters + terminator character), though most
responses are fewer than 10 characters. All responses end with the Terminator character as described in the
table above.
Acknowledgment (No Error)
If the command was received and processed without error, the response is as described in the command's
description below. Generally, the response to a control command is identical to the string that was initially sent.
The response to a query command starts with the command string, followed by the requested parameter.

MC-LS Remote Operation Guide D20990.106 Rev A 7
Negative Acknowledgement (Error)
The following table describes the types of negative acknowledgments:
Type
Response
Invalid character received
Response: &nX^Y
&n = Negative acknowledgment
X = Characters in the command string that were parsed
correctly
^ = Invalid character location start
Y = Invalid character received
Examples:
Command: &L5
Response: &nl^5
(5 is not a valid parameter for this command)
Command: &HLZ
Response: &nhl^z
Explanation: The characters "HL" are the first letters of a
valid command, but the "Z" is not.
Buffer Overflow
Response: "USB receive buffer error" or "Uart receive buffer
error," depending on which port experienced the overflow.
The error message is transmitted after a Start Character (&)
is received, followed by 63 non-Termination Characters.
Termination Character received
before Start Character
Response: "Invalid command"
Timeout
Response: &n
Once the Start character is received, a timer is started.
Whenever another character is received, the timer is reset. If
10 seconds elapses since the last character was received
and that character wasn't the Terminator, the MC-LS
responds as described.
The timeout timer stops when a timeout occurs or if the
Terminator is received.
