Product Overview
DESCRIPTION:
The IN31608 Presentation Switcher combines the easy operation and serial control capabilities of a projector
switcher with the flexibility of a matrix switcher. Featuring RGBHV + stereo audio matrix switching, 350 MHz
bandwidth and two switching modes, the IN31608 is ideal for permanent installations, rentals, complex staging
operations and any other display system requiring a high performance, economical presentation switcher.
Direct Switching Mode - In the Direct Mode, the IN31608 acts as a projector switcher, routing composite, S-
Video and RGB signals to the appropriate outputs. The user simply presses one of the input buttons and that
input signal is automatically routed to the pre-programmed output(s).
Matrix Switching Mode - For advanced applications requiring multiple outputs, the IN31608 can operate as a
true 16 x 8 matrix switcher. In the Matrix Mode, users press an output button followed by an input button and a
new patch is immediately executed.
Projector Control - The IN31608 can store and transmit serial ASCII or hex projector control strings to
projectors, INLINE products or other serial controlled AV equipment in RS-232, RS-422 or RS-485 modes.
Windows
projector control strings are provided by the installing technician.

Switching - Connecting Inputs and Outputs (Front Panel)
DIRECT MODE
Press the button of the input you desire and the signal will automatically be sent to the appropriate output(s).
Video, sync and audio are always routed together as a group (see DIRECT MODE SETUP on page 7 for more
details.) That input LED will light as well as any of the selected output LEDs. To disconnect all outputs press
the Blank Button.
MATRIX MODE
To make a new connection between an input and an output, the order of button presses is always output then
input as described below.
First press the button of the output you would like to change. The selected output LED will light (only one
output can be selected at a time). The LED of the input currently patched to that output will also light. To
select a different input, press the button of the input you desire. To blank the output, press the Blank Button.
Once an output is selected, the inputs may be changed indefinitely.
GROUP CONFIGURATION (MATRIX MODE ONLY)
In Matrix Mode, it is possible to switch video, sync and audio together or separately using the front panel
Switching Mode Button or the serial commands.
Board Group Selection from the Front Panel - Switching multiple board groups is possible through the front
panel. To select the switching mode depress the Mode Button. The switching mode sequences between three
possible combinations in the following order:
1) VIDEO / AUDIO / SYNC (default) - video and audio LEDs on
2) VIDEO / SYNC ONLY - only video LED on
3) AUDIO ONLY - only audio LED on
Board Group Selection Using Serial Commands - It is also possible to switch audio, video, and sync
together, separately or in almost any combination using the serial [CNF…] command. The [CNF…] command
defines three groups. Each group is treated as an independent switcher within the unit, and can be switched
independently. The factory default is to have all boards assigned to Group 1 so that they switch together.
One of the most common uses of assigning multiple groups is to switch audio independent of video. Assigning
the RGB and sync boards to Group 1, and the audio to Group 2 will accomplish this. Doing so allows Group 1
and Group 2 can be switched independently.
The IN31608 allows breakaway audio, video and sync in any combination through serial commands. However,
there are only video and audio LEDs on the front panel to make this distinction. When sync is switched
separately from video and audio, the unit automatically disables the front panel input and output switches and
flashes the video and audio LEDs. The switcher is designed this way to protect the user from setting a
breakaway sync mode with a serial command and subsequently switching the front panel manually without
realizing that sync is being switched separately from audio and video.

SWITCHING EVENT ORDER
The following procedure describes the precise order of events each time a switch is made.
1) Wait for:
a) Next sync signal (genlock operation / vertical interval switching only), or
b) Timer time-out, whichever comes first.
2) If video included in switch group (video always included in switch group for Direct Mode):
a) Update video array for particular in-to-out channel.
b) Set video switch to array but don’t update yet.
3) If sync included in switch group (sync always included in switch group for Direct Mode):
a) Determine which input is currently connected to the output in question.
b) Disconnect and update sync array (if sync channel is currently connected).
c) Connect new sync channel and update sync array.
4) RGB delay - Variable delay time according to value set for RGB Delay.
5) If video included in switch group (video always included in switch group for Direct Mode):
a) Update video switch.
6) Send projector codes:
a) If output changed, send projector output code and wait for projector code delay.
b) Send projector input code.
7) If audio included in switch group (audio is always included in switch group for Direct Mode):
a) Determine which input is currently connected to the output in question.
b) Disconnect and update audio array (if audio channel is currently connected).
c) Update audio volume for particular in-to-out channel.
d) Connect new audio channel and update audio array.
Genlock Operation / Vertical Interval Switching
The IN31608 can provide genlock operation / vertical interval switching when used with synchronous video
sources. The unit has two BNC connectors on the rear panel to allow loop through of a house sync or black
burst signal.* If this sync signal is active, the IN31608 will delay the switch so that it begins with the leading
edge of vertical sync. Genlock operation / vertical interval switching is disabled while in factory default mode,
and may be enabled by pressing Output 4 during power up (see page 9). Alternatively, the [VIS0] and [VIS1]
serial commands disable and enable the genlock operation / vertical interval switching, respectively. Refer to
the Switching Event Order section above for the precise order of events each time a switch is made.
*Note: When using the loop through feature, the unused BNC connector requires a 75 Ohm termination plug (IN9130).
RGB Delay
RGB Delay is a key feature of the IN31608. It provides an adjustable delay time between switching the sync
and RGB boards. The delay time can be set from 0 to 6 seconds (in 500 millisecond intervals) by front panel
power up settings or serial commands.
When RGB delay is engaged, the sync signals are connected first and the video and audio signals are blanked
for the delay time to allow the display device to lock up to the new signal. After the delay time, the video and
audio signals are connected. When set to the factory default of 0 seconds, video, sync, and audio switch at the
same time. The RGB delay can be set via a Power On setting or via serial commands (see those sections for
more detail).
2001 - INLINE, Inc. IN31608 OPERATION MANUAL - REV 1.6 1/4/01
4
sizing and other spurious
RGB delay prevents the display device from showing reon-screen effects that often occur while the display is adjusting to the new signal.
Audio
In Matrix Mode, the audio for the selected input is routed to the selected output. Note that the video, audio, and
sync may be switched independently in Matrix Mode. In Direct Mode the audio of the selected input is sent to
the selected output(s). The front panel volume control and the serial volume commands are mutually
exclusively enabled. On power up, the front panel volume controls are enabled and the serial volume
commands are disabled. The serial command [MDVOL0] enables the front panel volume controls and disables
the serial volume commands. The serial command [MDVOL1] disables the front panel volume controls and
enables the serial volume commands.
The IN31608 has Volume Up and Down Buttons as well as a Mute Button. These buttons function as follows:
VOLUME UP / DOWN
The Volume Up Button increases the output volume and the Volume Down Button decreases it.
Matrix Mode - When the Volume Up / Down Button is depressed the volume of the currently selected output
volume is incremented / decremented. If the button is held for one second, a fast increment / decrement mode
is entered and the Output Button’s LED flashes until the maximum / minimum output volume is reached.
Direct Mode - The volume control for Direct Mode works similarly to the volume control for Matrix Mode
except that the output volume is controlled simultaneously for all outputs.
The output volume information is retained in non-volatile memory and can only be modified by the procedure
described below or the serial volume commands [VOL…]. In Matrix Mode, output volume information is
retained separately in non-volatile memory for all 16 channels. In Direct Mode, a global output volume control
is retained in non-volatile memory that controls all outputs.
MUTE
The Mute Button disengages the audio signal. When the audio is muted (no audio) the mute LED turns on. The
audio will remain muted until it is reactivated by pressing the button again. In the Matrix Mode, the audio of
the currently selected output is muted. In the Direct Mode, all outputs are muted simultaneously. Muting does
not affect the previously selected input or output volumes. The mute information is retained in non-volatile
memory and can only be modified by the procedure described above or the serial command [MUTE…]. In
Matrix Mode, mute information is retained separately for all 16 channels. In Direct Mode, a global mute
controls all outputs.
VOLUME UP / DOWN AND MUTE FOR [SW] COMMAND
An alternative way of adjusting the volume and mute settings (associated with the [SW] command) with
a serial command (such as [LVOL…]) is to make the adjustments as described above, then press the
SAVE key followed by the BLANK key. The current volume and mute settings will override the
settings previously stored and will be used with subsequent [SW] commands.
IN31608 OPERATION MANUAL - REV 1.6 1/4/01 2001 - INLINE, Inc.

INPUT VOLUME
If the Mute Button is depressed simultaneously with the Volume Up / Down Button, the input volume for the
currently selected input is affected instead of the output volume. In this case the Input Button’s LED flashes
until the maximum / minimum input volume is reached. By adjusting input levels, the levels of all the various
input sources can be equalized. This is important so the volume level does not increase / decrease dramatically
when switching between inputs. The input volume information is retained in non-volatile memory and can only
be modified by the procedure described on the previous page.
The actual volume adjustment is calculated by adding the input volume setting and output volume setting
together, and truncating the total at a maximum setting of 255. The total volume is mapped to a linear scale
from -96.0 dB to +31.5 dB in increments of 0.5 dB. A total volume of 0 corresponds to -96.0 dB and a total
volume of 255 corresponds to +31.5 dB. The default input value is mid scale (128) to allow for maximum input
volume adjustment in both directions. The default output value for both left and right channels is 52, so that the
default sum of input and output volumes for both left and right channels is -3 dB.

Projector Control Port
The projector control port can be used to control a piece of equipment via RS-232, RS-422 or RS-485. The
communication parameters of the port are set via the serial [PCPPxx] commands. The projector codes are stored in
non-volatile memory. This feature is enabled / disabled by the [PCP…] command. When the IN31608 performs
certain actions, a code is transmitted through the projector control port. Codes are sent as follows:
Input and Output Codes - Each input and output can store an ASCII or hex code that may be transmitted when a
switch is made.
1) If a switch is made where the output changes, the associated output code is sent. Then a delay
defined by the [PCPD…] command is implemented.
2) Regardless of changes in output, the associated input code is then sent.
Function Buttons -
activated (the LED turns on) and the other is sent when it is deactivated.
Recall Codes - When a memory is recalled, a code is sent. Codes can be stored for memories 1 through 16.
For test purposes it is possible to send the projector control codes through the serial control port as well as the
projector control port by first issuing the serial command [PCP2].
Function Buttons F1, F2, F3 and F4 each hold two codes. One code is sent when the button is
Serial Control Port
PROTOCOL
The IN31608 baud rate may be selected from 1200 to 19,200 baud with the serial [ACI] command.
9600 baud (default)
No Parity
8 data bits
1 stop bit
These settings are stored in non-volatile memory.
STRUCTURE
All commands sent to the unit must contain a leading character (identified by the command code), followed by the
actual command and an ending character (also identified by the command code). Each command must be completely
executed by the IN31608 before it will accept a new command. The IN31608 provides a response to all commands
received. If the IN31608 executes the command, the response is sent after the command execution. When a
command is executed, the unit provides the response [OK] to indicate that the command was received and executed.
Do not send a new command until the [OK] is received, otherwise there may be a conflict. The responses have the
same beginning and ending characters as the commands that elicited the responses. Some examples of responses are:
RESPONSE INDICATION
[OK] Command received and executed
[INVALID COMMAND] Command as received does not exist
[INVALID PARAMETER] Parameter is out of range
[INVALID MODE] Command does not apply to current IN31608 mode
[GROUP CONFLICT] [CNF] command groups must be mutually exclusive
Some commands, such as the various [STAT] commands, have specific responses (see the Serial Control Command
Description section on the next page).
IN31608 OPERATION MANUAL - REV 1.6 1/4/01 2001 - INLINE, Inc.
11
A successful response from the IN31608 is issued after execution of the command
Except for the ACI and CMDCD commands. The response to the ACI command is
sent at the existing baud rate, and then the baud rate is changed. The response to
the CMDCD command is sent with the existing command code and then the command code is changed.
COMMAND CODE DEFINITIONS
The IN31608 can recognize one of four sets of leading and ending characters, also called the command codes. These
are: [ ] { } ( ) < >. The factory default for the command code is [ ]. The command code can be changed via
the serial [CMDCD] commands. The command codes are stored in non-volatile memory.
A complete command string consists of: Some sample command codes follow:
[ The leading character [CALL01] Recall setup memory 1
CALL02 The actual command [RGB3.0] Set RGB Delay to 3 seconds

Troubleshooting
Problem 1: The power switch is on but all of the front panel LEDs are dark.
Solution 1: Make sure that the AC cord is securely plugged into the unit and the AC source.
Solution 2: Make sure the AC source is live.
Solution 3: Check the IN31608 fuse and replace if necessary.
Problem 2: A video glitch occurs during switching.
Solution 1: If vertical interval switching (VIS) / genlock operation is not required: 1) disable it with serial
command [VIS0], or 2) disable it by pressing the POWER ON and OUT4 Buttons simultaneously.
Solution 2: If VIS is required, make sure that a valid GENLOCK INPUT SIGNAL is attached to the unit.
Solution 3: If projector codes are not required, disable them with serial command [PCP0].
Solution 4: If projector codes are required, use the highest baud rate [PCPPxx], the minimum projector code
length [PCLxx] / [PCHxx], and the minimum delay possible [PCPDx].
Problem 3: There is no response from serial commands.
Solution 1: Make sure that the baud rates of the controller and the unit match ([ACIx] or 9600 factory default).
Solution 2: Make sure the controller is configured as eight data bits, one stop bit and no parity.
Solution 3: Make sure that the correct command codes are being used ([CMDCDx] or ‘[]’ factory default).
Solution 4: Make sure that the connector cable is properly inserted into both / all units.
Solution 5: The controller must wait for a response to each command. Make sure that the command buffer is
not overwritten.
Problem 4: Audio / video LEDs on the front panel are flashing, and front panel input and output
commands are not responding.
Solution: See GROUP CONFIGURATION on page 2.
Problem 5: Front panel is locked up (no response).
Solution 1: If all LEDs are off, refer to problem 1.
Solution 2: If video and audio LEDs are flashing, see problem 4.
Solution 3: Cycle power while depressing Mute Button (toggle front panel enable), or send serial command
[FP1] (front panel enable).
Solution 4: Cycle power while depressing the F1 Key (factory default). Unit should come up in matrix mode.
Problem 6: Front panel volume control does not respond.
Solution: Enable front panel volume control with serial command [MDVOL0] or cycle power while
depressing the F1 Key (factory default).
Problem 7: Serial volume commands result in INVALID MODE responses.
Solution: Enable serial volume control with serial command [MDVOL1].
