DNT900 - 11/05/08
Tx Timeout
- this parameter sets the transmit timeout used for determining message boundaries in trans-
parent data mode. Units are in milliseconds. The default is that a message boundary is determined
whenever there is more than a 5 ms gap detected between consecutive characters.
whenever there is more than a 5 ms gap detected between consecutive characters.
MinPacketLength
- sets the minimum message length used for determining packet boundaries in trans-
parent data mode. The default is one byte.
TransLinkAnnEn
- enables a link announcement function for transparent mode. Whenever link is acquired
or dropped, the strings "<LINK>" or "<DROP>" are sent to the host.
EscapeSequenceEn
- enables or disables the escape sequence which can be used to switch from trans-
parent mode to protocol mode. Enabled by default. Valid settings are 0 = disabled, 1 = one chance at
startup, 2 = enabled at any time.
startup, 2 = enabled at any time.
TransPtToPtMode-
controls the behavior for addressing packets in transparent mode. When this setting is
zero (default), in transparent mode the base will direct packets to the broadcast address. This is useful for
point-to-multipoint where the base is sending data to multiple remotes, for instance in applications where
a wireless link is replacing an RS-485 serial bus. When this setting is one, in transparent mode the base
will direct packets to the last remote that registered with it. This is useful for point-to-point networks where
there are only two endpoints, for instance in applications where a simple serial cable is being replaced.

GPIO0. .5
- writing to these registers sets the corresponding driver for pins that are enabled outputs.
Writing to pins that are enabled as inputs enables or disables the internal pull-up. Reading these registers
returns the current level detected on the corresponding pins.
returns the current level detected on the corresponding pins.
ADC0. .2
- read-only, returns the current 10-bit ADC reading for the selected register. See the discussion
of the ADC_SampleIntvl parameter below.
