AVP-16 ADA Bus & Control Wiring
Suite 16 without other ADA components or Keypads
If you are controlling just an ADA Suite 16 from a non-ADA control interface (i.e. touch screen
control system), you can connect directly to the Suite-16’s rear panel RS-232 jack. Please
note, that the front panel and rear panel jacks are in parallel and as such, only one can be
used at any one time. Thus, if you use the rear panel connection for the control system, the
front panel connection will not operate in the event you wish to use your PC and the Suite-16
Setup software.
Suite 16 with other ADA Bus Components (i.e. Trinity Tuner) but no ADA Keypads.
If you are using other ADA Bus Components, such as the Trinity Triple Tuner or a Cinema
Rhapsody (or Reference) Home Theater Preamplifier, yet still only using a non-ADA control
system, you will most likely want to network the ADA Bus components on the ADA Bus. By
using a WH-2000 Wiring Harness and an ISO-232 ADA Bus to RS-232, you can connect the
Suite-16 and other devices directly to the WH-2000 along with the ISO-232. By using the
ISO-232 as your RS-232 interface, you can now communicate to all ADA Bus Components
through a single control system I/O. Furthermore, you free up the Suite-16’s RS-232 port
(either front or rear panel but never both at the same time) for connection to PC for program-
ming using the Suite-16 Setup software.
ADA Bus Wiring Connection
ADA Bus wire by specification is a three conductor 18 gauge tin-coated copper wire with an
overall braided shield that is 90% braid. These connections are shown in the heavy black
lines in the diagram to the right. In the event ADA Bus wire is not available, you can use a four
conductor 16 gauge speaker cable. Please note, that ADA Bus connections are intended
strictly for short runs, to connect ADA Bus components to the WH-2000 Wiring Harness.
Because Suite-16 runs at a baud rate of 19200, long runs of this cable will cause inter-compo-
nent communication to fail. To maintain the best operation at the faster baud rate of 19200,
ADA recommends limiting ADA Bus wiring to a total of 15 feet in length (that is the total
distance of all ADA Bus runs). As ADA Bus components are typically in the rack with the
Suite-16, several short ADA Bus connectors, 2 feet in length, are usually employed.
Suite-16 with ADA Controls
When using ADA Keypads including the MC-5011, MC-5000, MC-3000, MC-3800, MC-3000
OD or MC-3800 OD, you will need to wire them with a Cat. 5 cable and RJ-45 connectors at
both ends. Standard Cat. 5 cable can be used in runs up
to 700 feet in length per run. Clean termination of the RJ-
45 jack is essential as this wire carries both control and
feedback in addition to voltage. A short in this wire can
disrupt control and even damage both keypads and main-
frame components. Tone out all terminations prior to con-
nection. In the
event a Cat. 5
cable is damaged,
see alternate wir-
ing options on the
next page.
