Embedding Relay Commands In A Smart Macro - Universal Remote Control MSC-400 Programming Manual

Control IN on a Power Amplifier (it is also connected to the 12V Convenience Terminal on the MSC-400 as the
source of the control voltage). The Relay configuration is Normally Open (NO). When the ON Command is
issued, the Relay will close, 12V will be present on the mini plug and the amplifier will turn ON. When the
OFF Command is issued, Relay 1 will open, the control voltage is cut and the amplifier turns OFF.
The exact opposite would occur if the Normally Closed (NC) configuration were used. When the ON
Command is issued, the Relay will open, interrupting normal operation, and when OFF is issued, the Relay
will close and the normal function will resume.
Both examples are also true of the Press and Hold options, the difference being, with the Latching ON and
OFF commands, the Relay remains open or closed until the next command is issued. With Press and Hold, the
Relay will open and close with the same logic, but now, will remain open or closed only for as long as the
command is being sent from the remote, or, for the duration set in Minimum Press Time.
Relays can be embedded into Smart Macros and will execute as programmed as steps in System ON/OFF or
Source Select Macros without any additional programming. However, in order to control a Relay with a button
press from a remote, a Macro Group: Relay Commands, will need to be setup in order to create the RF Triggers
required for control of the Relay from a remote. To program Relay Commands:
