Recalling a Configuration
To recall a configuration, press the RCL button, followed by an input or an output button, marking
the setup number. For example, press RCL followed by INPUT# 3 button to recall Setup # 3 from
the internal non-volatile memory of the switcher. To abort an operation of the RCL button once it
was pressed, press it again.
7.2.10
Deleting a Setup
To delete a setup, press both the STO and the RCL buttons followed by the input button
corresponding to the setup number, which is to be deleted.
7.2.11
Using the Take Function
To activate the " TAKE " Function, press the TAKE button (the TAKE button illuminates). After
each pressing of the above-mentioned buttons, the TAKE button blinks together with the relevant
numbers in the STATUS display. Confirmation of the action is implemented by pressing the TAKE
button again (the TAKE button then stops blinking). If the STATUS display keeps on blinking for
one minute (no button is pressed), the function will be aborted. To abort implementing an operation in
“TAKE” mode, press that button which originally caused the display to blink.
7.2.12
Resetting the Machine
To reset the machine, press INPUTS buttons "1", "2" and "3" simultaneously. The machine resets
itself and a 7-segment self-test is automatically performed.
Using the Rear Panel Controls
The switcher ID numbers, the RS-232 / RS-485 settings, and the sync source selection are all
configured on the rear panel of the machine.
7.3.1
Selecting the Sync Source
Input sync selection is made using the "Sync Select” button located on the rear panel. For an external
sync operation, press the “Sync Select” button. For an internal sync operation, release the “Sync
Select” button. This modifies the input circuitry to select the required input sync source.
7.3.2
Setting the Configuration Switches
Setting the configuration switches is accomplished through a bank of DIP switches located on the rear
panel. Table 3 describes the settings and configurations for each of the DIP switches. 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 3.
Master/Slave DIP switches configure the Matrix Switcher for operation in a multiple switcher
configuration. If a Matrix Switcher is operating and being controlled independently, it should be
assumed that it is operating in the “Master” configuration.
Up to 8 Matrix Switchers may be cascaded for control via a single port by configuring one Matrix
Switcher as a "master", or ID number "1", while all the others are assigned as slave Matrix Switchers
or an ID other than "1". When RS-232 connection is implemented, DIP switch # 8 allows you to
enable RS-232 communication between the Matrix Switcher and the PC. This is desirable, so that the
controlling device “knows” that the controlled device has carried out its instructions. When RS-485
connection is used for communication between the Matrix Switcher and the PC, DIP switch # 8
should be up ("OFF"). In some applications, it may be desirable for some machines not to reply to
instructions received on the RS-232 and RS-485 ports. In this scenario, you would disable the
“Reply”, or acknowledgement commands. DIP switch # 5 enables or disables "reply" from the
Matrix Switcher to the PC.
In the case of interconnection between more than two RS-485 receivers-transmitters (including PC),
the termination resistor must be disconnected on all the devices, except the first and last machines on
the communication line. DIP switch # 4 connects or disconnects the termination resistor.
