3 Overview
The VP-1608 16x8 RGBHV/Balanced Audio Matrix is a true matrix
switcher, routing any input to any or all outputs. The VP-1608 includes 16
input and 8 output selector buttons.
The unit features:
 A bandwidth of 400MHz (fully loaded) for RGB signals
 A unique vertical and horizontal sync-pulse solution
 Audio-follow-video or audio breakaway option (to switch audio
independently from video)
 15 preset memory locations for quick access to common
configurations
 A “TAKE” button for precise switch control, letting you place
multiple switches in a queue, and then activate them, with one
touch of this button or a single serial command
 A delayed switching mode (ranging from 0 to 3.5sec1
Control the VP-1608 using the front panel buttons, or remotely via:
), for clean
transitions when switching between non-genlocked sources
 RS-485 or RS-232 serial commands—that also support audio gain
adjustments for each input and output—transmitted by a touch
screen system, PC, or other serial controller
 The Kramer RC-IR2 Infrared Remote Control Transmitter
The VP-1608 is dependable, rugged and fits into three vertical spaces (3U)
of a standard 19" rack. To achieve the best performance:
 Connect 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)
 Avoid interference from neighboring electrical appliances and
position your Kramer VP-1608 away from moisture, excessive
sunlight and dust

5 Installing the VP-1608 in a Rack
This section describes how to install the VP-1608 in a rack.
Before Installing in a rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (5 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
 In some models, the front panel
may feature built-in rack ears
 Detachable rack ears can be
removed for desktop use
 Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
 If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5 to +45 C (41 to 113 F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20 to +70 C (-4 to 158 F)
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.

To connect a PC to the VP-1608 unit1
 Connect the RS-232 9-pin D-sub (F) rear panel port on the
VP-1608 unit to the null-modem adapter and connect the null-
modem adapter with a 9-wire flat cable
, using the null-modem adapter
provided with the machine (recommended):

To connect a PC to the VP-1608 unit
to the RS-232 9-pin
D-sub (F) port on your PC
1, without using a null-modem adapter:
 Connect the RS-232 9-pin D-sub (F) port on your PC to the
RS-232 9-pin D-sub (F) rear panel port on the VP-1608 unit2, as
illustrated in Figure 7 (depending on whether the PC has a 9-pin
or 25-pin connector)
1 When connecting a single VP-1608 unit via RS-232, set the MACH. # DIP-switches to Machine # 1, according to Table 4
2 Up to 50 feet of cabling may be used for the RS-232 connection

6.3 Controlling via RS-485
You can control a VP-1608 unit via an RS-485 controller1
To connect an RC-3000 to a single VP-1608 unit (see
, for example, a
PC (equipped with an RS-485 interface) or a Master Programmable Remote
Control system, such as the Kramer RC-3000.
Figure 8):
1. Connect the RS-485 terminal block port on the RC-3000 to the RS-485 port
on the VP-1608 unit, as follows:
 Connect the “A” (+) PIN on the RS-485 rear panel port of the
RC-3000 to the “A” (+) PIN on the RS-485 rear panel port of
the VP-1608 unit
 Connect the “B” (-) PIN on the RS-485 rear panel port of the
RC-3000 to the “B” (-) PIN on the RS-485 rear panel port of
the VP-1608 unit
 If shielded twisted pair cable is used, the shield may be
connected to the “G” (Ground) PIN on one of the units (for
example, on the RC-3000)
2. Set the MACH. # DIP-switches on the VP-1608 unit to a Machine #
between 2 and 16, according to Table 4. Do not set as Machine # 1 (the
Master). Terminate the RS-485 line on both the VP-1608 unit (set DIP 4 to
ON) and on the RC-30002
1 RS-485 can be used for control even for distances exceeding 1km
.

Figure 8: Controlling via RS-485 (for example, using an RC-3000)
6.4 Setting the MACHINE # DIP-Switches
The MACHINE # determines the address of a VP-1608 unit when several
VP-1608 units are controlled by a PC or serial controller. Set the
MACHINE # on a VP-1608 unit via DIPS 1, 2, and 3 (DIP 4 is for RS-485
termination), according to Table 4.
When using a stand-alone VP-1608 unit, set the MACHINE # to 1.
When connecting more than one VP-1608 unit, set the first machine (the
Master) connected via RS-232, as MACHINE # 1. The other VP-1608 slave
units (each set to a MACHINE # between 2 and 8) interconnect via their
RS-485 ports to the RS-485 port on the Master.

connected to the “G” (Ground) PIN on one of the units (for
example, on the RC-3000)

Matrix
This section describes how to operate the VP-1608. The section includes:
 Choosing the Audio-Follow-Video or Breakaway option (see
section 8.1)
 Switching OUT-IN combinations (see section 8.2)
 Confirming settings (see section 8.3)
 Storing/recalling input/output configurations (see section 8.4)
 Adjusting the audio gain control (see section 8.5)
 Locking and unlocking the front panel (see section 8.6)
 Resetting the VP-1608 (see section 8.7)
 Displaying unit characteristics (see section 8.8)
8.1 Choosing the Audio-Follow-Video or Breakaway Option
By default, the VP-1608 is setup for use as a single machine. This means
that it is a 16x8 RGBHV/Balanced Audio Matrix (in audio-follow-video
mode), with all setups empty and each input connected to its corresponding
output (for example, input 1 to output 1). The DIP-switches are set up for a
typical application using a single machine (see Figure 11):
Figure 11: DIP-Switch Setup on a Single Machine
You can switch stereo audio signals in one of two ways, either:
 Audio-follow-video (AFV), in which all operations relate to both
the video and the audio channels; or
 Breakaway, in which video and audio channels switch
independently
8.1.1 Setting the Audio-Follow-Video Option
To set the Audio-follow-video (AFV) option, press the AFV button:
 If the AUDIO and VIDEO configurations are the same, the AFV
button illuminates. The audio follows the video
 If the AUDIO differs from the VIDEO, the TAKE and the
AUDIO buttons flash. Also, the audio outputs in the INPUT
