Key
~
(tilde)
– Performs the same type of operation as the “
j
” key above except that
power (strong pull-up) is applied to the bus after the first bit is issued. (Subsequent bits
generated will not be followed by strong pull-up.)
Key
f
–
Performs a 1-Wire bus “first” operation. This operation searches the bus and
finds the first 1-Wire or iButton device and displays the device serial number prefixed
with a “+” or “-“ character to indicate if there are more (“+”) or no more (“-“) parts
remaining to be found.
Key
n
– Performs a 1-Wire bus “next” operation. This operation searches the bus and
returns the next 1-Wire or iButton device, and displays the device serial number prefixed
with a “+” or “-“ character to indicate if there are more (“+”) or no more (“-“) parts
remaining to be found. (If used again after a “-“ response is received, this function finds
the first part again.) Note that if a Family Search (the
\f
command) is in progress, next
may return a “?” if encountering a family code overshoot.
Key
t
– When followed by a two-character hexadecimal value, will change the search
type to this function command value. Using “tF0” will make the search normal. Using
“tEC” will make the search conditional and will discover only devices for which the
search conditions are satisfied. (See the data sheets for each individual Dallas iButton or
1-Wire device for specific search type command codes.)
Key
l
(lower case L)
– This will test the composite 1-Wire bus level and report a “0” if
any bus is low or a “1” if all busses are high, followed by a carriage return.
Key
x
– Forces all 1-Wire busses to a low level. Cancelled by a reset (“r”) command or
any bit or byte command to restore the 1-Wire busses to operation. This function is used
to cause a bus-wide reset by robbing power from all devices on the busses for a few
seconds.
Key
z
– Turn off the sw5V line to the LinkHub-E output connectors.
Key
d
– Turn on the sw5V line to the LinkHub-E output connectors.
Key
&
–
Report the current intended state of the sw5V line on the LinkHub-E
output connectors.
Key
$
–
Start arrival/departure scanning (See
Scanning
below.)
Key
*
– Report scan list. If scanning is NOT active the response is a single carriage
return character. (See
Scanning
below.)
Key
\
(
backslash
) – Escape character for a LinkHub-E expanded command set
command. The \ command by itself does nothing. It must be followed by an expanded
command character. This differs from a standard Link which uses this key for sniffer
mode that is not supported by the LinkHub-E.
