P
ROCESS RS232 INPUT
(Factory Default = “ENABLED”)
This setting should be enabled when the RS232 port will be used to receive data to control the MRC88m
System from a PC or other RS232 device. If the RS232 port will only be used to control an external device from
the Keypad (thermostat controller, lighting system etc..), disable this setting to prevent the MRC88m system
from misinterpreting erroneous data.
NOTE: To control the MRC88m System from the RS232 port, please see Section 5: RS232 Input Translator
and Section 9: Appendix-RS232 Control.
MONITOR LOCKOUT MODE
(Factory default: “DISABLED”)
This mode is only accessible if ‘Priority Lockout’ is enabled. If Priority Lockout is not selected (system is in
Whole House Mode), the Monitor Lockout Boxes are grayed out and therefore cannot be selected. Once the
boxes are accessible, checking the corresponding boxes prevents sources from being monitored (audio and
video) and controlled in specific zones. Example: If adult content is not to go to the children’s areas, this can be
set at the time of system installation. When a Source is selected in a zone that is checked, a message stating
MONITOR LOCKOUT will be displayed in the zones keypad LCD window and now video and/or audio for that
source will not be able to be monitored. To enable MONITOR LOCKOUT for a particular Zone/Source complete
the following instructions:
1. Select “PRIORITY LOCKOUT MODE” under MODE OF OPERATION. The Monitor Lockout boxes will
be activated.
2. By Zone, click in the box of each Source that is NOT to be monitored in that zone.
