The software download file is transferred to the G2BT Station remotely through the LAN
using TFTP, or locally through the front panel serial port using Xmodem or Ymodem
protocols. When one of the methods has been activated but not yet completed, the other
method handling is disabled (any data received using that protocol is ignored).
•
TFTP (Trivial File Transfer Protocol)
The transmitter functions as a TFTP client; in this mode, the software download file will
be “pulled” or downloaded by the station from a predefined server. The server IP address,
download date, time and file name is specified through the user interface or through SNMP
MIB sets.
During download, the system keeps information on the number of packets that have been
transferred with or without success and the number of packets that have been transferred with
success. There are also user specified values to control the timeout value from packet ack/err
sent and the next packet received, number of retries that the station will send packet err to the
server before aborting the session and interval from when the station receives a data packet to
when it sends a packet ack/err.
•
Front Panel Serial Port
The software download file can be transferred locally using the serial port and specifying the
Xmodem or Ymodem protocols through the serial program (typically Hyperterminal or
ProComm).

The software download file always contains all binary images for the SCM software, the DSP
software and the FPGA configuration code.
