Downloading Message Files
This chapter shows how to use menu option 9 - Message File Download to
download message files from a computer to a DL20 Display.
Note: It is recommended that you use option 8 - S Record/Message File
Upload (Read)/Download (Write) to download large numbers of messages.
The S Record file transfer is more efficient and faster.
Before transferring files between your computer and a DL20 Display, you
must connect the equipment using the appropriate cable. The figure below
