Alcorn McBride Digital Video Machine DVM-7400 User’s Manual Rev 1.5

GPS sensors need a

“line-of-sight” to the

sky in order to receive

strong satellite

signals. For the sake

of reliability, operation

indoors or in long

underground tunnels

is not recommended.

6. You’re now ready to begin entering GPS trigger points. Get in your vehicle!

Place the GPS sensor on the roof (or other mounting location recommended

by the GPS sensor manufacturer). Click on the first entry in your GPS

playlist. Drive to the first desired trigger point and hit the Space Bar when

you reach it. GPS Builder will record the coordinate and advance to the next

line. After this point all you need to do is hit the Space Bar each time you

want to log another coordinate.

7. Drive to the next trigger point and hit the Space Bar again. GPS Builder will

record the next coordinate. Keep doing this until all of your coordinates have

been entered.

8. Click on File…Save…to save your file. Make a backup!

9. Copy the playlist to the Compact Flash card you’re going to use in the DVM,

along with all of the videos referenced in the playlist.

Proceed to the next section to learn how to use this playlist in your DVM.

Configuring the DVM for GPS Operation

Now that you have your playlist file with the GPS coordinates, you can use it in the

DVM. Here’s how.

First, make sure that the DVM GPS Mode DIP switch is in the OFF (UP) position. It’s

DIP Switch #2 on the 2-key DIP switch block.

Connect the Alcorn McBride GPS harness (comes with the DVM GPS kit) to the DB-

37 port and the RS-232 port of the DVM.

Connect the GPS sensor to the mini DIN connector of the GPS harness.
