DekTec DTM-3200 IP-ASI Converter - Manual (Page 25)

DTM-3200 – OEM Ethernet TSoIP Converter
User Manual
25
Starting from firmware version 1.4, for each 7 bits of data one 8-bit ASCII character is send, where
the MSB of the ASCII character is set to 1 (extended ascii range). The translation is illustrated in
Figure 8.
This encoding is only applied to the data-part of the "File part" message. (category 0x80, setting
0x02). The rest of the messages are encoded as before.
An example of a firmware update sequence and an example routine for the above translation can
be found in paragraph 4.5.
4.4.6 IP receive settings
The IP receive settings are available only if the DTM-3200 is configured as IP-to-ASI converter.
