depending upon the PC used.

names of the Þles will vary in accordance with the current
software revision. The Þle name should look similar to the
following: Vxxxxx.RAM.

DL3800 comm port conÞguration. Default conÞguration for the
DL3800 is 9600 Baud, 8 bits, No parity, 2 stop bits. Connect the PC
serial port to the DL3800
COMM PORT .
