To save data from the JANUS 2050 to the host computer
1. Connect the JANUS 2050 to a host computer using the communications
port. The JANUS 2050 transmits and receives data at 4800 baud, no parity,
8 data bits, and 1 stop bit.
2. Run a communications program, such as Crosstalk, that saves data on the
host computer. This program is not provided with the JANUS 2050.
3. If the Boot Loader menu is not already displayed, request the menu by
turning the JANUS 2050 off. Press

The JANUS 2050 downloads data from low memory (640K and below)
through COM1 to the host computer. The data is transmitted in Intel
hexadecimal file format.
5. A record counter on the JANUS 2050 display counts the data as it is
transmitted to the host computer. The record counter stops updating when
the JANUS 2050 is finished downloading the data. When the download is
completed, you can reboot the JANUS 2050 or reload the JANUS 2050’s
flash memory.
If the system flash memory is corrupt, reload the JANUS 2050 flash
memory as described in the next section.
Loading Flash Memory
If the JANUS 2050 Boot Loader menu displays a checksum error message or if
you need to upgrade the JANUS 2050 software, you can download all of the
JANUS 2050 flash memory from a host computer. Before replacing the
memory, upload any data you want saved from the JANUS 2050 to the host
computer.
CAUTION
Caution
If the Load System flash option is selected, all system data will be lost.
Conseil
Si l’option de chargement du flash système (Load System Flash) est
sélectionnée, toutes les données système seront perdues.
