2 - PROGRAMMING AND CONTORL AREA
2.1 - USB PORT
Connect the PMA amplifier to your computer at this port using a mini USB cable. Microsoft Win-
dows XP or Windows 7 will discover the PMA unit and install the required drivers. When doing
this for the first time, this process may take a few minutes. On subsequent connections, Windows
will install the driver more quickly. Refer to “Amplifer Programming” section of this manual for
more information.
Operating systems other than Windows XP and Windows 7 are not supported.
2.2 - 12V/CONTACT CLOSURE TRIGGER INPUT
Connect a 12VDC trigger output, or contact closure relay to this port using the supplied Phoenix
two-position male connector. The STANDBY/OPERATE TRIGGER will operate with applied DC volt-
age or with an open/short ciruit.
When connecting to a control system relay/contact closure output, program the relay to close
(short) the terminals to engage STANDBY; open the terminals for OPERATE. When connecting to
a DC trigger output, make sure to observe correct voltage polarity. Failure to do so could result in
damage to the PMA input or your component trigger output. 0VDC will engage STANDBY mode;
5VDC up to 12VDC will cause the amp come to out of STANDBY MODE and OPERATE.
3 - 12V/CONTACT CLOSURE LOOPING OUTPUT
Use this port to “loop” the Trigger input signal to another PMA chassis using the supplied Phoe-
nix two-position male connector. When using a DC trigger input, make sure to observe correct
polarity, or component damage may occur.
