Example 1

T:13:46 D:01/1/2010 E:COMMAND 1:"1PL"

This is the simplest possible example because it contains the minimum number of fields

needed to execute a scheduled event. Notice that the example occupies only one line of text,

and that each field is separated by a space. In order, this is exactly what each field means.

Start Time(T): 1:46pm in the afternoon (13:46 military)

Start Date(D): January 1

2010

Event(E): COMMAND – Specifies that parameter 1 contains a DVMHD command

Parameter 1(1): The command string “1PL” will cause the DVMHD to play file #1.

Example 2

T:14:46 D:01/1/2010 E:COMMAND 1:"RJ" ;Stop Playback

Two things have changed in this example.

Start Time(T): 2:46pm in the afternoon (14:46 military)

Start Date(D): January 1

2010. (same as Example 1)

Event(E): COMMAND (same as Example 1)

Parameter 1(1): The command string “RJ” will cause the DVMHD to stop playback.

Using Example #1 and Example #2 together in a schedule file will cause file #1 to begin

playback at 1:46PM on January 1

, 2010 and stop playback at 2:46PM the same day.

One other thing that is special about this event is that the comment “Stop Playback” has

been added at the end of the line using a semicolon(;). Anything found after a semicolon

is ignored by the scheduler. You can even place a comment on its own line, if you like.

Example 3

T:14:46 D:01/1/2010 R:30 P:minute A:1/3/2010 I:3:00 E:COMMAND 1:"1PL”

We’ve now added:

Repeat Number(R): 30

Repeat Period(P): minute

Ending Time(I): 3am in the morning (3:00 military)

Ending Date(A): January 3

2010

The Repeat Number acts as a multiplier of the Repeat Period. They should be read in

conjunction like this: “Repeat this event every 30

minutes”.

The Ending Time and Ending Date fields specify the time and date that the repeating will

stop. In this example, the DVMHD will play file #1 on 1/1/2010 at exactly 2:46PM. It will then

play the file again 30 minutes later (3:16PM) and will continue to repeat until 3:00AM on

1/3/2010.
