Xantech mrc88 installation instructions Testing Commands Under Power Management and Sense Triggers

Model MRC88 Page: 59

6.Select POWER OFF in the Macro Command List. The POWER OFF button will become outlined in RED.

7.Select the appropriate command(s) to be associated with the absence of a Sense Input (i.e. no video or 0VDC on the Ring of the stereo mini jack connected to the SENSE input).

8.Repeat for all trigger inputs desired

POLARITY AND WIRING OF SENSE INPUT

TIP = +12VDC Output

RING = Input (+12VDC)

SLEEVE = Ground

When using a dry contact closure to activate a Current Sense Input Trigger, the switch should be connected between TIP and RING through a 220ohm resistor.

When using an external trigger voltage, (12 VDC control out from switched source, etc.) the switch should be between SLEEVE and RING.

CURRENT SENSE DE-BOUNCE SETTINGS

“De-Bounce” is the amount of time switches and relays need to stabilize. The factory default of ‘2’ should be tried first. For a faster switch, try the ‘1’ setting. For slower switches change as needed to allow the controller to sense the switch or relay condition.

TESTING COMMANDS UNDER POWER MANAGEMENT AND SENSE TRIGGERS

Commands may be tested in the same manner as on the Virtual Keypad. To test commands, the Dragon PC must be connected to the front panel COM PORT or USB Port and emitters must be placed in the proper Source and Zone IR Emitter output ports. For Fast Testing, an emitter placed in the COMMON IR port will be sufficient.

1.Select the Sense Trigger to be tested with the IR codes placed under it to test. The Trigger should now be hi-lighted.

2.Select the TEST button located in the bottom right-hand side of the Power Management window. Commands listed under the Macro Command List for that selected sense trigger should now be executed in order of appearance out of the proper Emitter Ports on the MRC88 Controller.
