Resetting the Machine
To reset the machine, press INPUTS buttons “1”, “2”, and “3” simultaneously. The machine resets itself,
and the video and audio 7-segment display will display a set of numbers. The video display will show
“1604” – indicating the machine type. The audio display will show, from left to right the following
information: the first two digits will show the machine’s address, the second two digits will show the
machine number, the third and fourth two digits will show firmware version. For example, when the
audio display shows: 2.11.1.2 it means that the machine’s address is 2, machine number is 11, and
software version is 1.2. When the machine is turned ON, the audio display shows the machine number
on the first digits, followed by the machine address.

Using the Back Panel Controls
The switcher ID numbers, and the RS-232 / RS-485 settings are all configured on the back panel of the
machine as will be explained later.
9.2.14
Setting the Configuration Switches
Setting the configuration switches is accomplished through a bank of DIPswitches located on the back
panel of each matrix switcher. Table 3 describes the settings and configurations for each of the
DIPswitches. To set the configuration switches, confirm that power to the matrix switcher is OFF, and
with a small flathead screwdriver, move the DIP switches to the "
ON
" or "
OFF
" position as shown in
Table 3 and Figure 2. Master/Slave Dipswitches configure the matrix switcher for operation in a
multiple switcher configuration.
In the case of interconnection between more than two RS-485 receivers-transmitters (including PC), the
termination resistor must be disconnected on the first and last machines on the communication line.
The DIPswitches (see Figure 2) on the rear panel shold be set when the unit is operated via the RS-232
or RS-485 serial interface, or when it is interconnected with other units.
In the
VS-1604
unit the DIPswitch divided into three functional groups:
#1-3
-
Machine Address
#4
-
Reply
#5-8
-
Machine Number
The group “Machine Address” is used when building larger video/audio matrices only (see
“BUILDING LARGER VIDEO/AUDIO MATRICES”). In all other cases the state of the DIPswitches
1-3 is “OFF,OFF,OFF” (Machine Address = 1). All the units with Machine Address = 1 are enabled for
communication via both serial interfaces: RS-232 and RS-485. Units with another Machine Address
allow RS-485 communication only.
The Machine Address serves for interconnection between
VS-1604
units only, and is invisible for the
PC.
The switch group “Machine Number” is used for configuring the
VS-1604
units for operation in a
multiple switcher configuration. All the units of a composite larger matrix have the same Machine
Number. DIPswitch “Reply” serves for enable/disable of command transmition from unit to PC. In some
applications (for example, RGB configuration) it is necessary to disable commands transmition from all
the units with the same Machine Number except number one.
