8x2 Video Matrix Switch

1.
For each of the two outputs there is an 8-position DIP switch on
the Video Matrix Switch’s rear panel - labeled “GAIN A” for
“OUT A” and “GAIN B” for “OUT B” - that you can use to
control the gain applied to the corresponding
input signals. For each
of the eight inputs, calculate the total lengths of the video cables from
the source to each of the two destinations (the devices attached to
OUT A and OUT B). Then set the corresponding switch position (“1”
for input 1 through “8” for input 8 on either GAIN A for OUT A or
GAIN B for OUT B): Move it DOWN if the total length is 100 ft. (30
m) or less, or UP if the total length is over 100 ft. (30 m). (In the UP
setting, extra compensation is added to the signal to make up for the
high-frequency losses typical of longer cabling.)
2.
Run the included 6-ft. (1.8-m) DB9 cable from the two included
keypads to the DB9 female connectors labeled “KEYPAD A” and
“KEYPAD B” on the Switch’s rear panel. If you have either
monitor placed father than 6-ft. (1.8 m)
from the Switch, you can
use DB9 male to DB9 female extension cable such as CDB9-
xx
-MF to
run just as far to the keypad, up to the maximum of 300 ft. ( 90 m ) .
3.
Plug the output cord of the Switch’s power supply into the
Switch’s 5-pin DIN female power inlet. Plug one end of the power
supply’s input cord into the transformer’s IEC 320 male inlet; plug
the other end of the input cord into a
working AC outlet. Your
Video Matrix Switch system is now fully installed, as shown in Figure
3-2 on the next page.
4.
Now you can turn on all attached devices. The system should
power up in its last state, with each of the Switch’s outputs
displaying its last selected input.
If it does, the system should be
ready for continuous operation. If it doesn’t, check the rear-panel
LEDs to make sure the Switch is ON; check your devices and make
sure they’re ON; and check the cabling and make sure it’s all properly
connected. If everything seems like it should work but the system still
doesn’t, call HRT Technical Support.
