Logic Outputs: This 25-pin Subminiature-D (male) connector
provides Logic Outputs 1~16 (pins 1~16 respectively) and a
common ground (pins 17~25). Logic Outputs allow remote control
of external circuits (see Logic Outputs on pg. 8). From the factory,
all Logic Outputs are ‘off’ and access to them is available only
through Configuration (see Configuration on pg. 10). During
Configuration, remote control buttons and Logic Inputs may be
defined to control the various Logic Outputs, utilizing ‘on’, ‘off’,
‘toggle’, and ‘no operation’ commands (see Remote Controls on
pg. 4). Logic Outputs can control relays, indicators, or other
products having logic inputs (such as VSX41 Video Switchers).
Logic Inputs: This 25-pin Subminiature-D (female) connector
provides Logic Inputs 1~16 (pins 1~16 respectively) and a
common ground (pins 17~25). Logic Inputs allow remote control
of PMX84 input/output assignment & Logic Output functions via
external circuits (see Logic Inputs on pg. 6). From the factory, all
Logic Inputs are non-functional and may be programmed to
perform functions only through Configuration (see Configuration on
pg. 10). During Configuration, each Logic Input may be defined as
an individual input/output assignment, or as multiple input/output
assignments (such as a preset). Logic Inputs are defined to affect
input/output assignments using ‘on’, ‘off’, ‘toggle’, and ‘no
operation’ functions. Logic Inputs can be controlled via switches,
contact-closures, active driver circuits, or other products having
logic outputs (such as the ADVANTAGE
®
AGII and DRC 4+4).
Remote Inputs 1~4: These plug-in barrier strips accept up to four
optional remote controls (see Remote Controls on pg. 4). Remote
controls may be infrared, wall-mount, and/or customized, and may
be wired up to 2000 feet away from the PMX84. From the factory,
Remote Inputs 1~4 are non-functional and may be programmed to
perform functions only through Configuration (see Configuration on
pg. 10). During Configuration, each remote control button on
Remote Inputs 1~4 may be defined as an individual input/output
assignment, or as multiple input/output assignments (such as a
preset). Control buttons are defined to affect input/output
assignments using ‘on’, ‘off’, ‘toggle’, and ‘no operation’ functions.
Each control button can have different functions assigned to it,
depending upon which Remote Input (1~4) it is received from.
This is an effective way to customize remote control functions for
specific zones or locations.
Override: This plug-in barrier strip terminal provides an
‘emergency’ (override) function. Override operates like a Logic
Input, and is activated when shorted to the adjacent ground (
ý
).
However, Override maintains a higher priority than any other Logic
Input or remote control button. When Override is released (no
longer shorted to ground), the PMX84 will automatically revert to
its previous settings, and to normal operation. From the factory,
Override is non-functional and may be programmed to perform
functions only through Configuration (see Configuration on pg. 10).
During Configuration, Override may be defined as an individual
input/output assignment, or as multiple input/output assignments
(such as a preset). Override is defined to affect input/output
assignments using ‘on’, ‘off’, ‘toggle’, and ‘no operation’ functions.
The Override terminal performs the functions defined for button
#40 on Remote #4. When Override is activated (shorted to
ground), the front panel Error Indicator will flash continuously, and
all Serial Port, PMX Link, Logic Input, & Remote Input 1~4
commands will be ignored.
PMX Link: This plug-in barrier strip terminal provides a ‘linking’
interface between multiple PMX84s within a system. PMX Link is
a communications bus, which allows Remote Input & Logic Input
commands received by one PMX84 to be ‘shared’ by all PMX84s
in the system. However, the way that each PMX84 in the system
responds to these ‘shared’ commands can be completely different,
as defined during Configuration (see Configuration on pg. 10). To
‘link’ multiple PMX84s, connect the PMX Link and adjacent ground
(
ý
) terminals from each PMX84 to the respective terminals on the
next PMX84, in a parallel fashion.
NOTE: RS-232 commands
received at the PMX84 Serial Port are not included at PMX Link.
Serial Port: This 9-pin Subminiature-D (male) connector provides
an RS-232 Serial Port. PC Control Software and a serial cable are
provided (see Configuration on pg. 10). The Serial Port also
allows remote control via computer, or via third-party controllers
which use the RS-232 protocol (see Computer Control on pg. 13).
AC Power Cord: The power transformer provides 27 Volts AC to
the PMX84, and is detachable via a 5-pin DIN connector. The
PMX84 has two internal ‘self-resetting’ fuses (there are no user
servicable parts inside the unit). If the internal fuses blow, they will
attempt to re-set after a short period. However, this may be an
indication that the PMX84 requires service.
