MX-4248 I/O Module Option
The MX-4248 I/O module has 24 alarm inputs and 8 contact outputs. If
the MX-4248 I/O Module is installed, the alarm inputs replace AIU-100,
address 0, alarms 1 through 32. Alarms 25 through 32 on AIU-100,
address 0, are not available. However, a host computer can use alarms
25 through 32. The MX-4248 I/O module alarms are handled the same
as alarms from an AIU-100. MultiCalls must be assigned to the MX-
4248 alarms for the CCU to respond to them. When the CCU receives
an alarm, it starts the MultiCall assigned to the alarm.
The MX-4248 I/O module has 8 contact outputs. The contact outputs
are controlled using camera address one. Auxiliary control commands
for camera address one are sent out COM 2.
3.2.4
Time Initiated MultiCall
The CCU can be programmed to perform MultiCalls at specific times with
specific intervals.
Examples:
- A MultiCall can be programmed to run every day at 5:00 p.m.
- A MultiCall can be programmed to run every hour.
- A MultiCall can be programmed to run every other day.
Up to nine MultiCalls can be assigned to date and time and stored in the
CCU. Note that MultiCalls can contain other MultiCalls including itself. This
feature can be used to perform continuous complex video switcher
sequencing and/or full scale video tours of a facility.
