The DL20 can transfer message data and system attributes to an EPROM
file. The EPROM file can be used to burn an EPROM. When this EPROM
is inserted into a DL20, message and system attributes cannot be modified.
Use EPROMs as a reliable method of programming multiple DL20s with
identical messages.
Appendix C describes how to transfer the EPROM file. Data is sent as an
EPROM file in S record format using the RS-232 port.
Important: EPROMs can only be created from DL20s with 16K memory
programmed or less. Make sure the ECHO TO ALL SLAVES special
function is not selected when using the EPROM function.
DL20 Operation Using an EPROM
Instructions for installing an EPROM are provided in Chapter 9. After an
EPROM is installed in a DL20, it will overwrite the RAM memory. There
are some restricted modes when using an EPROM:
DL20s enter run mode on powerup. You cannot enter edit mode.
The following special functions are not accessible:
Tape Operations
Burn PROM
Clear RAM
Set Up Master
Set Up I/O Ports
Other than these restrictions, the DL20 functions like a DL20 using RAM.
