Remote Interfaces            

Note: The LED TEST switch is a pushbutton type.

The AUTO/MANUAL, REMOTE/LOCAL switches are

mom-off-mom type.

The AUDIO mute switch is on-off

The controller has 3 remote modes available to the user.  In order to avoid conflicts, these control points (Remote/Local modes) are selectable only from the local front panel. The REMOTE 232/485  mode is used for the available computer interface.  RS232, and RS485 are dip switch selectable within the control unit.  Other protocol criteria, such as, Address, baud rates, CR,LF, ignoring checksum errors, and parity settings are also dip switch selectable. (see documentation for further detail). Computer Protocol

REMOTE 422 is the remote mode setting used for an optional remote panel.  The remote panel is identical to the local panel, with all of its indicators and functionality, with the exception of being able to choose between the Local/Remote modes of operation.  The remote panel is connected to the local rear chassis via a 6 conductor cable.  It is recommended that a shielded cable be used, with the shield tied to chassis ground.  The remote unit may be placed up to 4000 feet away from the local unit.  (Note that if the controller is placed in RMT 422 mode without the remote panel actually being there, the local command switches are essentially locked out.  Some users place the unit in RMT 422 mode so inadvertent changes can’t happen.)

RMT STD is the remote mode used for monitoring and controlling the system via dry contact closures.  The remote indicator outputs are available on the remote STD port at all times.  There are remote indicators for all faults and mode settings.  The RMT STD command inputs are only recognized by the controller while the controller is in the RMT STD mode of operation.  A command input thru this port is entered by temporarily connecting the command with the command common for approximately 50 mSec.

Important note on remote switch position indicators:

The switch position indicators are taken off of the switches themselves.  A second set of indicators are needed on the switches in order for them to be transferred over to the Remote Standard port.  See pins J1-6,7,8 on rear chassis.

All indicators on the Remote Standard port are form A relays, or Normally Open.
