UPDATING MODEL 192E TO OPERATE WITH 195EG

firmware has been updated, all the programming instructions in this User’s Manual will be applicable. The following firmware
update procedure requires the ESTeem 192E to first be updated to firmware version 220.19. Once this has been verified, please
proceed.

to the FTP server before proceeding.

a. 192eupdate.sh
b. 192epdrs.sh
c. swupdate-192e-230.dev.65.img
d. DOS2UNIX.EXE
3. Open the 192eupdate.sh file using Wordpad. Replace <server-IP> with the IP of your ftp server. Replace <version> with the
firmware version (e.g., 230.dev). For example:
4. Save the amended script file.
5. Open a Command Prompt.
