Product Overview
DESCRIPTION
The CTL101 interface converts contact closures and infrared (IR) signals to RS-232, RS-422 or
RS-485 serial commands. The unit allows complete systems integration and system control via a
single computer workstation, contact closure and / or infrared remote. The CTL101 can also be
used to remotely control a VCR, DVD, INLINE unit or any other IR receiver equipped device by
passing along IR remote signals.
PRODUCT FEATURES
• Three Command Sources - Commands can come directly from the host computer. Prepro-
grammed commands can be sent by using an IR remote control or via any of the 16 contact
closure ports.
• Infrared Remote Control - provides one touch operation of programmed system functions
and allows the presenter to move freely around the room.
• Remote Operation - The CTL101 allows operators to connect a local IR emitter directly to
control equipment (that is IR receiver equipped) and transmit remote signals from over 1000
feet away.
• Serial Input and Output Ports - allow the CTL101 to pass along commands from a compu-
ter or other control system to the controlled equipment.
• On Screen Display Menus - are provided by the CTL101 for the control computer monitor.
• Easy Setup - A Terminal Emulation Program is the only software necessary to set up the
CTL101…no special software is required!
• Versatile Mounting Capability - The CTL101 can be placed / mounted in a variety of loca-
tions or fits neatly in a 1U rack space (when mounted in a standard 19" equipment rack).
• Optional Equipment:
CTL120-1 IR Remote Control - sends infrared commands to the CTL101. This hand-
held generic unit can be customized with labels to match specific installation
requirements.
CTL120-2 IR Remote Control with Overlay - is the same remote with an overlay that
specifies which buttons control the IN1402 / IN1403 / IN1404 Video Scalers, IN3600
Series Switchers and IN31608 Matrix. A diagram outlining the location and function of
each button can be found on pages 27 - 29. Complete operating / programming
instructions are provided in the CTL120 Operations Manual.
CTL130 IR Emitter - acts as a signal transponder in that it allows operators to control
video equipment that may be out of the IR remote’s line-of-sight (i.e. rack-mounted
equipment, devices located in another room, etc.).
CTL131DB / CTL131DW IR Sensor - is an IR sensor (housed in a double size A/V
connector module) that can be mounted in a remote location and relay control signals up
to 1000 feet (available in black or white).

Installation
This section offers step-by-step instructions for installing the CTL101 Control Interface. Serial
Port Wiring Diagrams are provided on pages 4 - 6, Application Diagrams are included on
pages 7 - 11, and a Front and Rear Panel Connectors and Controls Diagram can be found on
page 13. All connectors and controls are located on the back of the unit.
Note: Installation of the CTL101 must only be carried out by qualified technicians. Read the
instructions carefully before initiating the installation procedure. Make sure that there is no
power connected to any of the units.
1.) Set the Dipswitches - as appropriate for your installation (if applicable). See pages 13 & 14
for more details.
2.) Place / Install the CTL101 Interface - at the desired location. Make sure that the IR sensor
window remains unobstructed.
Sunlight and direct reflections can sometimes cause the CTL101 IR sensor
to activate inadvertently. Avoid placing the unit near bright light sources
and / or areas where light reflection may affect the unit’s performance.
3.) For Rack-Mount Installations - Secure the CTL101 to the optional IN9080 rack mount
shelf using two (2) #6 - 32 x ¼" long screws (provided with the rack shelf). Two interfaces
can be mounted side-by-side on a single rack shelf, or a single unit may be mounted along
with an optional IN9088B blank plate. Together, the CTL101 and the IN9088B fit snugly in
a 1U rack space.
Note: When attaching any INLINE unit to an INLINE rack mount shelf, the four (4) rubber feet
must be removed from the bottom of the unit.
4.) Control Signal Connections - Make one or more control signal input / output connections as
appropriate for your installation:
 Connect the Computer or Control System Serial Port to the RS-232 / RS-422 /
RS-485 Serial Port Input (see Wiring Diagrams on page 4 thru 6 and Application
Diagram A on page 7). The CTL101 is configured from the input port using a host
computer in terminal emulation mode. See the Terminal Emulation Parameters
Section on page 16 for more details on configuring the CTL101.
 Connect Serially Controlled Devices such as the IN1402 / IN1403 / IN1404 Video
Scaler, IN3600 Series Switcher or IN31608 Matrix to the RS-232 / RS-422 / RS-485
Serial Port Output (see Application Diagram A on page 7).
 For Contact Closure - connect all switches to the Contact Closure Input Ports. The
CTL101 has 16 isolated ports. See the Wiring Diagram on page 6 and Application
Diagram C on page 9.
 For Applications Involving IR Controlled Products -connect the 2-pin captive screw
connector on the CTL130 IR Emitter to the CTL101 IR Out Port (see Application

CTL101 Operation Manual - V1.3 03/22/02 ©2002 - INLINE, Inc.
Diagram D on page 10). The mouse type emitter attaches directly over the IR sensor of
the device being controlled (when used to control a single unit) or can be mounted up to
three feet away from the IR controlled devices when used to control multiple units.
Note: Emitters are to be used for local control of video equipment only (i.e. the video
equipment and the CTL101 are in the same room).
Do not place the CTL101 in a location where the unit’s sensor window
will detect the emitter signal, or in an area in which the signal could feed
back into the unit. This condition is evident whenever a remote control
command is issued and the remote light on the CTL101 remains "ON"
even after the remote control button is released.
 For Remote Sensor Applications - Connect the CTL131DB / CTL131DW IR Remote
Sensor to the IR Sensor Input Port (see the Wiring Diagram on page 6 and Application
Diagram D on page 10). The sensor can be mounted in a remote location and can relay
signals to the CTL101 from up to 1000 feet away. Set the Sensor Mode button to the
EXT position.
6.) Turn on - the computer, monitor, INLINE equipment and all other connected / controlled
devices.
7.) Apply power to the CTL101 - using the IN9230 power cord (included). The power LED on
the front of the unit will illuminate.
8.) Set-Up the Terminal Emulation Program. Users can access the Set-Up Menu by typing an
Asterisk (*). Complete details are provided on pages 16 - 23.

CTL101 Connectors and Controls
FRONT PANEL INDICATORS
The Remote and Power LED’s, and the IR receiver sensor are located on the front panel of the
CTL101 (see the diagram on the following page). The Power LED will illuminate as soon as
power is applied to the unit (the CTL101 has no ON/OFF switch). The Remote LED will
illuminate whenever the interface receives an infrared signal from any IR remote control.
REAR PANEL CONNECTORS AND CONTROLS
All connectors and controls are located on the back of the unit, and the dipswitches are located on
the bottom (see the Dipswitch Bank Tables on page 14).
Sensor Mode - is located on the left rear of the CTL101. This switch allows users to toggle
between the unit’s internal IR sensor and the remote sensor. When the switch is in the INT
position (down), the unit’s internal IR sensor is active (factory default). In the EXT position
(up), the remote sensor (attached to the IR Sensor Input) is active.
IR Sensor Input - is a 4-pin captive screw terminal that connects directly to the CTL131DB /
CTL131DW IR Remote Sensor (see Application Diagram D on page 10).
Contact Closure Ports - allow users to connect up to 16 devices with contact closure capability
(see Application Diagram C on page 9).
RS-232 / RS-422 / RS-485 Serial Ports - The Output Port connects directly to the IN1402 /
IN1403 / IN1404 Video Scaler, IN3600 Series Switcher or IN31608 Matrix or any other device
that accepts ASCII command strings. The Input Port connects directly to the computer
workstation (see Application Diagram E on page 11).
IR Out - connects to the CTL130 IR Emitter via a 2-pin captive screw terminal (see Application
Diagram D on page 10).
Fuse - 0.25A, time delay
Power - Universal power: 90 - 260 VAC, 47 - 63 Hz.

©2002 - INLINE, Inc. CTL101 Operation Manual - V1.3 03/22/02
DIPSWITCH SETTINGS
On the bottom of the unit are two sets of dipswitches. Dipswitch Bank #1 is used to configure
the serial ports to operate as an RS-232, or RS-422 / RS-485 physical interface. Dipswitch Bank
#2 is used to isolate the contact closure ports and to configure the CTL101 to the default baud
rate (9600). The factory default and specialized dipswitch settings are listed below:
Factory Default Settings:
Dipswitch Bank #1:
Dipswitches 1, 2, 3, 4, 5 & 6: All in "0" position
Input Port Serial Mode: RS-232, no termination
Output Port Serial Mode: RS-232, no termination

DIPSWITCH BANK #1
Dipswitches 1, 2 and 3 control the Input Port, while 4, 5 and 6 control the Output Port. The Input
/ Output port will operate in RS-232 mode when all six dipswitches are in the "0" position
(default), and in the RS-422 / RS-485 mode when all six dipswitches are in the "1" position.
Switching pairs 2 & 3 and 5 & 6 will terminate the receive & transmit signals (respectively) at
their ports.
DIPSWITCH BANK #2
In most cases, the contact closure ports use internal power from the CTL101 to sense changes
(switches 1 & 2 are enabled). Users can completely isolate the remote contacts & wiring from
the CTL101 by incorporating an external +5 volt power supply into the system (see the CTL101
Contact Closure Inputs Diagrams on page 6). In such applications, the internal power supply of
the CTL101 must be disconnected from the contact closure ports by disabling dipswitches 1 & 2.
When dipswitch #4 is in the "0" position (normal), the CTL101 automatically recalls the last
configuration at power-up. Users can override the last settings and power-up the unit at factory
default (9600 baud) by setting the switch to the "1" position (override). Note that the factory
default also sets the Code End / Menu Call character to an asterisk (*).

Serial Port Set-Up
Preprogrammed command functions can be sent via the RS-232 / RS-422 / RS-485 serial output
port. The CTL101 accepts serial commands from a control system, computer serial port or any
other device capable of sending out serial ASCII commands at compatible baud rates, and relays
the commands to the video equipment via the output port.
RS-232, RS-422 & RS-485 FORMATS
RS-232, RS-422 and RS-485 formats are physical interface standards for serial communication.
RS-232 is a full duplex operation that is typically used for short distances (up to 25’). RS-232
full duplex is the most common format and is limited to point-to-point applications (i.e. one
computer, one piece of equipment). It is not designed for the simultaneous usage of several units
or for sending serial information over very long cable lengths.
RS-422 and RS-485 formats can operate in both full and half duplex modes. In half duplex
mode, only one unit can transmit information at any given time. Therefore, other units in the
system will not respond until the initial transmission is concluded, and only one unit can respond
at any given time. Half duplex mode is preferred for applications involving multiple devices and
/ or communication along fewer lines.
Note: Configuring the CTL101 for full or half duplex serial port operation is discussed in the
Serial Port Control Section on pages 20 - 22.
Both RS-422 and RS-485 formats are designed for longer cable runs (actual lengths depend on
cable grade, capacitance and a number of other variables). RS-485 is recommended when
operating multiple units on a single line.
Reflections will sometimes occur when signals are sent over long cable runs
(in the RS-422 / RS-485 mode). If a system incorporates several units and /
or long control cable runs (while operating in full duplex mode), users can
minimize reflections by setting dipswitches 2 & 3 and /or 5 & 6 to the "1"
position (on the CTL101) and / or by engaging the termination resistors on
the units located at opposite ends of the control cable (see diagram on page
5). For half duplex applications, engage switch 2 and / or 5 only.
COMMUNICATION PROTOCOL
1 start bit 1 stop bit
8 data bits no flow control (factory default setting)
no parity check 9600 baud (factory default setting)
BAUD RATE SELECTION
The CTL101 has a factory default baud rate of 9600 bps and can communicate at baud rates from
1200 up to 115,200.
Note: The baud rate of the computer / A/V equipment must match the baud rate selected on the
CTL101 (both the input and output port are set to the same baud rate).
If communication is lost, use the default switch on the bottom of the
CTL101 to reset the unit to factory default (9600 baud).

TERMINAL EMULATION PARAMETERS*
In order for the workstation to communicate with the CTL101, the terminal emulation program
parameters must be set as follows:
Enabled:
VT100 Terminal Emulation
Echo Typed Characters Locally (sending)
Wrap Lines that Exceed the Terminal Width (receiving)
Disabled:
XON / XOFF Control
Hardware Flow Control
Echo Received Characters
* Software comes standard with the Windows™Package.
By default, the CTL101 is set up to accommodate most common terminal emulation programs. If
the unit is not communicating properly (i.e. unwanted text / messages appear on the screen, double
spacing occurs between menu choices, menu selections are followed by "error" responses, etc.),
set the parameters to full duplex, no delimiter pause and no flow control, then check the emulation
program set-up. Refer to the Serial Port Control Section on pages 20 - 22 for more details.
CTL101 Set-Up Menu
Power-up the CTL101 and open the systems terminal emulation program. Type in an asterisk (*)
to bring up the setup menu. With Firmware Revisions 1.2, you may change the asterisk to any
character you choose.
Note: Whatever character you select, you may not use it in any command string.
The Main Setup Menu will look like this:
*CTL101 Main Menu - please enter selection.
1. Switch codes.
2. Infrared codes.
3. Serial Port.
4. Delimiter pause.
5. Set Code End character.
5. Self Test.
6. Exit.
CONTROL CODES FOR CONTACT CLOSURE
If the application involves control codes for contact closure, type "1" in the main menu followed
by ENTER.
A new feature includes Hexadecimal code entry (HEX format). HEX format codes must be
entered in pairs (even number of entries). Also, in ASCII format, Carriage Return (Ctrl M) and
Line Feed (Ctrl J) may now be entered as part of the code string (they were previously ignored).
HEX format code entry must be in capital letters "0-F" (Version 1.1 or later in self test).
