Power Up
Turn the Power switch ON. The REMOTE-2 PN Series waits for valid
programming commands during the first 20 seconds after POWER ON.
If no valid commands are received within that time, the instrument
recalls its last stored parameters (or default settings) and starts
counting.
If a programming command is received within the first 20 seconds, the
command is examined and, if valid, the associated parameters are set
and stored in non-volatile memory, overwriting the previous values.
The instrument waits another 20 seconds for the next command and the
process repeats for each command that is sent. When no more valid
commands are received, the timer times out and the instrument loads
the stored parameters and uses them to begin counting. Old parameters
are used if they were not modified during the program session.
Lighthouse recommends that, before powering up the instrument, a list
be made of the commands to be used and parameters to change. This
avoids unnecessary time outs.
Sample
Session
Hyperterminal should be running BEFORE applying power to the
REMOTE-2 PN Series.
1. Apply power to the instrument. The Rxxx2 "program mode"
prompt is sent by the unit.
2. The next commands must be performed before the instrument
"times out" or the startup steps will have to be repeated.
Note:
The commands
discussed require the <
(shifted comma) and >
(shifted period) characters;
they mark the start and
end of the commands.
3. Type:
<V>
-- this is Verbose mode. This must be the first
command sent if you wish to see responses
from the instrument
4. Type:
<?>
-- the unit ’ s current settings are displayed .
Note:
The flow rate
displayed will be according
to the model - 0.1 cfm for
the R3012PN and
R5012PN or 1.0 cfm for
the R3102PN and
R5102PN.
