3 Overview
The 88 Series is a group of 8x8 Vertical Interval Matrix Switchers1 and a
Remote Control Panel for video/stereo audio/data signals that support the
simultaneous connection of one or more inputs to several outputs2. Vertical
Interval Switching3 ensures an undisturbed picture transition. The major
innovation with the 88 Series is the ability to switch different kinds of signals
simultaneously. Section 3.1 outlines the 88 Series and section 3.2 includes
recommendations for achieving high quality performance.
3.1 The 88 Series
The 88 Series includes the following items:
VS-88A (stereo audio matrix switcher for analog balanced audio)
VS-88V (video matrix switcher for analog composite video)
SD-7588A (audio matrix switcher for digital audio)
SD-7588V (video matrix switcher for digital video)
VS-8000 (remote controller for use with the switchers)
3.2 High Quality Performance Recommendations
Achieving high quality performance means:
Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Using good quality sockets and connectors for the sources and acceptors to
avoid signal path breaks4. Aim for Zero Ohm connection resistance and ensure that
sockets and connectors match the required impedance (75 ohms in video)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality. Install unbalanced audio and video lines5 (even
though the cables are shielded) away from mains carrying cables, electric motors,
and transmitters
Positioning the switcher correctly. Each switcher is housed in a professional
1 They ensure smooth and glitch-free transition when sources share a common reference sync
2 However, you cannot connect two or more inputs to a single output
3 Frequently used when recording or transmitting a video program involving several video sources
4 Poor quality connectors tend to rust, which may cause breaks
5 Balanced audio lines are less prone to interference

You can connect up to 24 remote controllers and up to 8 switchers per
system. However, when connecting less than 8 switchers, you can connect
more remote controllers1.
5.4 Connecting Several Units and the PC
To connect several units and the PC, connect the following:
Power supply
Audio and/or video input and output cables
Reference input (for video) for VS-88V and/or SD-7588V
Set the dipswitches for the different MACHINE #. Set dipswitch # 5 OFF and
dipswitch # 6 ON
Switchers in a daisy chain arrangement2 using the RS-232 In and RS-232 Out
DB9 connectors should be connected using a flat-cable, or with at least the three
wires (pins # 2, # 3 and # 5)3. Do not use a null-modem adapter. Assign PC port
to 9600, N, 8, and 1
Figure 8 illustrates a typical system connection with both4 the RS-232 and the
RS-485 connected in a parallel line:
Figure 8: System Connection: Switchers and the PC
1 RS-485 connection supports up to 32 devices, that is, switchers and remote controllers. For example, when connecting 2
switchers per system, you can connect up to 30 remote controllers
2 The 88 Series firmware complies with Kramer Protocol-2000 (version 3.1 and higher)
3 Make one-to-one connections (that is, uncrossed)
4 Often the PC has no RS-485 Com port and so both are required simultaneously

5.5 Connecting a Component1, Y/C, RGBS or RGBHV Switcher
A component2 switcher consists of 3 VS-88V switchers, interconnected as
one group, with one of the switchers set as the Master. A component switcher
can function in the IN SYSTEM or standalone mode. Similarly, you can
configure 2 VS-88V switchers for Y/C (s-Video), 4 VS-88V switchers for
RGBS or 5 VS-88V switchers for RGBHV.
To set the VS-88V switchers in the group to operate as a single component
switcher, do the following with every switcher in the group:
Set the same MACHINE # for each switcher (for example, MACHINE # 2)
Set dipswitch # 5 OFF
Set dipswitch # 6 OFF (except on the Master, set Dipswitch # 6 ON)
Except for the Master (whose LEDs illuminate and front panel controls remain
unlocked), the LEDs on all switchers in the group are dimmed, and their front panel
controls are locked3
Figure 9 illustrates a component switcher that consists of a group of 3
VS-88V switchers:
Figure 9: Component Switcher: VS-88V Group Connection
1 For RGB or YUV (Y, B-Y, R-Y)
2 Video signal in component form offers the highest professional video quality, superior to composite or s-Video
3 After initially powering up the component switcher, if some of its switchers remain in a different status, press the ALL
button followed by the OFF button on the Master to reset all the connections prior to normal operation
Understanding the Modes
21
6 Understanding the Modes
This section describes the different system and confirmation modes.
6.1 About the System Modes
By default, a switcher starts in the standalone mode and the IN SYSTEM key
does not illuminate. Pressing the IN SYSTEM key twice toggles to the IN
SYSTEM mode.
This section describes the Standalone and the IN SYSTEM modes, as
follows:
6.1.1 Standalone Mode
In the standalone mode:
The switcher implements actions independently and separately from the others
Upon starting the system, only one MACHINE IN SYSTEM # illuminates on
the remote controller
6.1.2 IN SYSTEM Mode
In the IN SYSTEM mode:
Several switchers with different kinds of signals are connected as a system
operating as a universal switcher1
More than one MACHINE IN SYSTEM # illuminates2 to indicate the units
that are connected as part of a system. Each MACHINE IN SYSTEM # for those
IN SYSTEM units will not illuminate. However, on each of the IN SYSTEM units,
the respective IN SYSTEM button continues to illuminate
Any executed action affects all units in the system
6.2 About the Confirmation Modes
By default, the unit starts in the AT ONCE mode, that is, if an OUT-IN
combination is pressed, it will be implemented immediately. Pressing the
TAKE button twice, toggles between the CONFIRM and the AT ONCE
modes.
This section describes the CONFIRM and the AT ONCE modes, as follows:
1 Each switches in the same order according to the entered command, with one or more of them following the other units
2 The IN SYSTEM button on each unit also illuminates
Operation
KRAMER ELECTRONICS, LTD.
22
6.2.1 AT ONCE Mode
In the AT ONCE mode:
You save time
Actions require no user confirmation
Execution is immediate
No protection is offered to prevent the implementation of a wrongly entered
action
6.2.2 CONFIRM Mode
In the CONFIRM mode:
You have a method to help avoid making a mistake
Every action requires user confirmation
Execution is delayed until the user confirms the action
Protection is offered to prevent erroneous switching
7 Operation
This section describes the hardware of the machine and the operation of its
front panel controls.
For instructions on using the Windows 95/98/ NT TM Control Software, refer
to the separate user manual1, Kramer Control Software.
7.1 Technical Information
This section describes setup capacity, switching the power on, timeout and
the system settings.
7.1.1 Setup Capacity
From every switcher you can store up to 8 setups. From the PC you can store
up to 15 setups.
7.1.2 Switching the Power On
To switch the power on at all the switchers, do the following:
1. Verify, via the automatic self-test, that all switchers function correctly.
1 Included on the CD-ROM in .pdf format
Operation
23
2. Check the firmware version number indicated by the two fast blinking
digits on the display1.
To switch the power on at the remote controller, do the following:
1. Attach the power adapter plug to the power socket on the remote
controller.
2. Verify, via the automatic self-test, that all switchers and the remote
controller function correctly.
3. The Comm. Error LED will illuminate to indicate a problem2, if at all,
with any switcher.
7.1.3 Timeout
By design, every push button operation is subject to a 30 second timeout.
Failure to fully execute an action within 30 seconds will necessitate restarting
that action whilst the LED display will show the previous state.
7.1.4 System Settings Priority
The design excludes any priority3. Any operator4 can always override the
previous system settings. For example, in Figure 7: RS-485 System
Connection: Switchers and Remote Controllers, the system setting
implemented by the operator of Remote Controller # 24 will be the current
system setting until the operator of say, Remote Controller # 5, implements a
different system setting.
7.2 Push Button Controls
This section describes how to store, recall and lock/unlock settings.
7.2.1 Storing a Setting
To store a setting, do the following:
1. Press the STO button. The STO button blinks.
2. Press the Output #. The LED Output display # blinks5.
3. Press the STO button again. The memory stores the data.
1 For example, the digits 10 indicate version 1.0
2 For example, if a switcher is not connected, or its power is switched off
3 Between any or all of the following: remote controllers, front panel controls and a PC
4 Whether he operates a remote controller, a set of front panel controls or a PC
5 At this stage, pressing a different # changes the Output #
Operation
KRAMER ELECTRONICS, LTD.
24
4. The LED display returns to its previous state1.
7.2.2 Recalling a Setting
To recall a setting, do the following:
1. Press the RCL button. The RCL button blinks.
2. Press the Output #. The LED Output display # blinks2, displaying what
was previously stored.
3. Press the RCL button again. This recalls the stored data.
By design3, you cannot recall data that is stored in a particular unit from a
different unit. Each unit, even when set to the IN SYSTEM mode, stores its
own data separately.
7.2.3 Locking and Unlocking Settings
The remote controllers and the PC include a flexible locking4 mechanism for
safeguarding settings on switchers. To prevent changing the settings
accidentally5, lock your switchers. Unlocking releases6 the protection
mechanism.
From any remote controller you can lock and unlock the following7:
A specific switcher
All switchers
That specific remote controller
From the PC8 you can lock and unlock the following:
A specific switcher
All switchers
Locking a specific remote controller does not lock any other remote
controller. To lock all the remote controllers, press the TAKE and the STO
1 Nothing changes in the setup
2 At this stage, pressing a different # changes the Output #
3 On one occasion the same unit can function in the standalone mode, and on another occasion in the IN SYSTEM mode
4 Locking means that the front panel is locked. In all other respects (for example, recall, changing input and output), the
switcher still operates via the remote controller and the PC
5 Especially if the system is complex and the switchers are stored on a rack in another room
6 Restarting (perhaps due to an electricity failure) a switcher or a remote controller also releases the protection mechanism
(without wiping out the switcher settings)
7 You cannot lock/unlock from a switcher
8 You cannot lock a PC
Operation
25
push buttons on each remote controller separately. You cannot
simultaneously lock or unlock all the remote controllers from one remote
controller, or from the PC. When all switchers and remote controllers are
locked, the front panel switcher push buttons are inoperative. By design, only
specific1 remote controller push buttons will function, enabling the operator
to execute the unlock commands.
Section 7.2.3.1 describes how to lock the switcher and section 7.2.3.2
describes how to unlock the switcher. For a concise summary of the
locking/unlocking push button sequence, refer to Table 13 on page 26.
