User’s Manual InterCon-PrintServer

Use these commands for:
•
Transfer mode switched to binary
•
Timeout for retrying sending packets set to 30 seconds
•
Total timeout for transfer set to 15 minutes
tftp> binary
tftp> rexmt 30
tftp> timeout 900
If you wish to observe the transfer, switch to trace mode by entering:
tftp> trace
Upload the software update binary file (e. g.
po_828.bin
):
tftp> put po_828.bin
If trace is activated, the number of the sent and confirmed data packets are displayed. After
receiving the first data packet the Flash EPROM of the print server will be erased. After 10 seconds
the next data packets follow.
During the data transfer to the print server the red LED of the print server continuously shines. If the
TFTP protocol reports that the data transfer is finished, then the download of the software update
binary file is completed. Exit the TFTP protocol by entering:
tftp> quit
If a network error occurs during the download procedure the print server will wait for the next data
packet until the network is stabilised. If the timeout exceeds the pre-set value the TFTP protocol
terminates the data transfer. The print server must then be restarted.
After being switched on the print server will detect that the EPROM is not completely
reprogrammed. (Notice that the red LED is flashing very fast). The print server now waits for the
binary file transfer. Start the TFTP protocol and continue as described above.
