Controlling the Switcher
13
Note: In the following description, "R", "G", "B" refers to three different
switchers required for the RGB implementation.
1. Interconnect three,
OMX-SW6x1B
switchers via their RS-485 ports ("A" to
"A", "B" to "B", and so on).
2. On all the units except one, set the DIP 1 (Reply) OFF.
3. Set all the switchers to the same Machine number (DIPs 2, 3 and 4).
4. If RS-232 control is required, connect the PC via the null modem adapter to
the unit in which the "Reply" option is set to ON (the system may also be
controlled via RS-485).
5. To synchronize the machines (for vertical interval switching) to input#1 of the
G unit, daisy-chain from G'
s input #1 to the ext. sync input of R and continue
to the ext. sync input of B (using "T" connectors). Place the following jumpers
in their alternate positions: J22 and J20 in the G unit, and J21 in the R unit.
Also, ensure that the following jumpers are in their factory default positions:
J34 in all the units; J20 in the R and the B units; and J21 in the B unit. To
synchronize using an external sync signal, configure R and B as described
above, but this time daisy chaining from G'
s ext. sync. Connect the external
sync to G and set G'
s jumper J20 and J22 to their factory default positions and
J21 to its alternate position.
6. Now connect the R, G and B outputs of camera #1 to input #1 on each of the
switchers respectively, those of camera #2 to input #2 on each of the switchers
respectively, and continue until all five camera R, G and B outputs have been
connected to the appropriate switcher inputs, in the same order. Let us call
them switchers R, G and B.
7. Connect the single outputs of switchers R, G and B to the R, G and B inputs,
respectively, of a professional acceptor, such as a monitor or VCR.
8. Turn the power ON and select the input number to be switched to the acceptor.
7.5 Controlling Several Independent Switchers via a Single PC Port
1. Assign unique machine numbers to each switcher.
2. Connect via the null modem cable from the PC to the "Master" machine.
3. Interconnect the switchers via their RS-485 ports ("A" to "A", "B" to "B", and
so on).
