Model AC603A
6
2.2 Dip Switch Settings
The AC603A can be used to transmit Composite Video and Stereo
Audio instead of VGA to the receiver. However since the Video
signals are terminated differently than audio, you need to move the dip
switch to the proper position.
Use the Mode Dip Switch to select the video type for transmission.
The Sync Dip Switch is used to change the polarity of sync at the
receiver. If your remote display has trouble positioning the right and
left edges of the screen, then try putting the switch is +/+
NOTES
If the length of Cat5 Cable is longer than 300 feet you
may need to attach a power supply to the receiver unit. The
power supply will need to be the same as the sending unit (i.e.
9VDC regulated, Center Positive with 2.5mm connector). If there
is no image at the remote or the image is intermittent, you may
need a power supply at the receiver, please contact Black Box
to purchase one. Generally if the remote display device is
referenced to ground (i.e. the VGA connector ground or case, is
connected to power line ground) you should not need an
additional power supply to the specified maximum length of 500
feet
Do not connect this unit to any LAN device such as
network cards or hubs as this may damage the AC155A and/or
the LAN device. Use EIA/TIA 568B standard straight-through
patch wiring. Do not use crossover cables.
For cable runs of 300 feet or longer it is recommended
that you use a UTP cable that is optimized for video (low skew
cable). We recommend Belden Cable’s “Brilliance®
VideoTwist(tm)” Category 5 Cable for best results.
