The sampling field shows the word SAMPLING when the CMCF receives a valid signal from an LRU/LRM. The word sampling field goes away when there is an invalid signal or no input.
The header field shows WORD NO and/or BIT NO. This helps to identify the information in the scale header field.
The scale header field shows the word range or bit range for the data in the sampling field. The characters in the header field line up to identify the characters in the sampling field.
The sampling data field has three rows of the most recent data available to the display. The newest data is on top. Older data in is the middle row. Oldest data is on the bottom row. The data updates at a 1 HZ rate.
Use the direct entry field to enter signal specifications with the keyboard.
The sampling data field is 20 characters long. It shows the signal name from the input monitoring alias table.
Each input monitoring group has two dedicated buttons.
The FREEZE button is a toggle with RUN. The display shows RUN first with the system in the freeze mode.
RUN is available for selection when there is a signal to monitor. Select RUN to start the data to update at a 1 HZ rate. The selection changes to FREEZE. FREEZE causes the CMCF to stop the update rate.

The SIGNALS button is not available for use at this time.

Select UNITS to show the input monitoring units dialog box. The UNITS command selection is not available for these:
*
With no signal to monitor

*
Analog variables

*
Analog discretes.

Scroll Bar

The display cannot show all eight signals at once. The scroll bar gives access to the other groups. The scroll bar lets you scroll up or down one group at a time.
Buttons

RUN ALL is a toggle with FREEZE ALL. The display shows RUN ALL first with the system in the freeze mode.
RUN ALL is available for selection when there is a signal to monitor. Select RUN ALL to start the data in all input monitoring groups with a valid signal to update at a 1 HZ rate. The selection changes to FREEZE ALL. Select FREEZE ALL to stop the update rate.
If the selection shows RUN ALL and the user selects RUN on a group selection, the command selection changes to FREEZE ALL.

Text Entry Operation
To enter text directly from the keyboard, put the cursor over the direct entry field. The cursor changes to the text entry I-beam cursor. Use the keyboard to enter the signal specification and select RUN. Each signal specification is made up of several elements separated by the slash (/) symbol. These are the types of signals you can monitor by typing in signal specifications:
*
ARINC 429

*
ARINC 629

*
Analog variable or discrete

*
AIMS inter-module memory (IMM).

ARINC 429 Monitoring
The ARINC 429 signal specification has these elements:
*
Input destination

*
Bus type

*
Bus identification (ID)

*
Label

*
Source destination identification (SDI).

This is an example of a valid ARINC 429 signal specification:
* L/429/052/351/00
In this example, these are the elements of the ARINC 429 signal specification:
* "L" is the input destination
45-10-00

CMCS -INPUT MONITORING GENERAL INPUT PAGE

*
"429" is the bus type

*
"052" is the bus ID

*
"351" is the label

*
"00" is the DSI.

The input destination element identifies the AIMS cabinet as the destination of the signal. Use "L" for the left AIMS cabinet and "R" for the right AIMS cabinet.
The bus type element identifies this as an ARINC 429 signal specification. Use "429" to identify this signal specification as ARINC 429.
The bus ID element is a three character hexadecimal number that identifies the ARINC 429 input bus to AIMS. It is not necessary to enter leading zeros. The bus IDs are listed in the CMCF help screens and in chapter 31 of the systems schematic manual (SSM).
The label element is a three character octal number that identifies the ARINC 429 signal. It is not necessary to enter leading zeros.
The SDI is a two character binary number that describes the signal source and destination identification. The binary numbers identify left, right, or center. Enter "XX" for if you do not care.
