Connecting Cables - American Dynamics MegaPower 3200 Installation Manual

Connecting Cables

1. Connect the AD data line from the MegaPower
CPU to the DATA LINE IN BNC of the bay.
Loop the data line to other bays, if required.
2. Connect video coax cables to VIMs.
3. For bays other than a single bay or the last bay
of a series, connect coax cable from the output
of the data buffer module to the appropriate
input of the VOM or VOMs.
Note: Coax cables are not used if VOMs are in
the same bay as VIMs and the bay is a single
bay or the last bay of a series. In this case,
VOMs take data buffer outputs off the
backplane of the bay.
Note: An ADULP Universal Loop Panel is used
when ribbon cable is required to connect VIMs
to VOM-4s. The loop panel is typically used
when camera numbers exceed 1024.
For instructions on how to use the ADULP with
MegaPower 3200 switching systems, see AD
Universal Loop Panel Installation Instructions
8000-0900-01.
4. Connect video output devices, such as monitors
or video recorders, to one of the four outputs of
each VOM.
5. If using a data buffer module with video loss
detection, connect a modular cable from the
RJ-45 connector of the data buffer to one of the
RS-232 ports on the rear of a MegaPower CPU
set for VIDEO LOSS use.
Note: When a video loss is detected, the data
buffer module transmits a video loss message
via the RJ-45 connector according to the alarm
contact mode set for the data buffer module.
Pins 1 and 2 of this connector also provide a
logic level alarm contact. These pins connect to
the alarm contact inputs of an AD2096 alarm
interface unit, pin 1 to the A input and pin 2 to
ground.

INSTALLATION GUIDE
Note:
• If the AD2010DBVL is less than 2.1m (7ft) from
the CPU, connect the RS-232 port using the
modular cable supplied.
• If the AD2010DBVL is more than 2.1m (7ft) from
the CPU, or if the alarm contact output is used,
connect an 8-pin terminal box to the RS-232
port using the modular cable supplied.
Maximum cable length between an RS-232
device and the terminal box is 305m (1000ft),
using 18AWG shielded, computer grade cable.
• All American Dynamics equipment is configured
as RS-232 DTE (Data Terminal Equipment)
devices. For DTE-to-DTE connections, the
MegaPower CPU RS-232 port:
- XMIT pin connects to RCD (pin 4) of the
terminal box going to the AD2010DBVL.
- RCD pin connects to XMIT (pin 5) of the
terminal box going to the AD2010DBVL.
- Ground connects to GND (pin 7) of the
terminal box going to the AD2010DBVL.
Note: An AD2081 port expander connects up to
four AD2010DBVL modules to the CPU.
• AD2010DBVL-1x module connects to port A
• AD2010DBVL-2x module connects to port B
• AD2010DBVL-3x module connects to port C
• AD2010DBVL-4x module connects to port D.
