1. INTRODUCTION
The new key is able to operate with 4 different "objects":
– One instrument;
– A second key:
– A Personal computer;
– A Personal computer and one instrument.
The key is subject to different "rules" according to the different
connected object and to the action to be made.
Note: The key is able to store all the configuration
parameters of one instrument at a time.
1.1 Dialogue between Keys and Instruments
It is possible to perform two different actions:
– Copy parameter values from an instrument memory to the
key memory.
– Copy parameter values from the key memory to an
instrument memory.
No specific rules must be enabled when copying the
instrument memory to the key memory (is always possible);
this action copies all parameters (when present, also the
program parameters).
On the other side, to copy the key memory data to an
instrument, prior to perform the transfer to the controller,
the conditions that guarantee the configuration integrity are
tested.
These conditions ensure that the configuration that we are
sending to the controller:
1. Has been created for the same instrument type;
2. Uses the resources built in the instrument itself.

1.2 Dialogue between two keys
This action is subject to no specific rules (is always possible)
this action copies all parameters (when present, also the
program parameters [thermal profiles]).
The dialogue between two keys of different type is not
allowed (a new key with an old one).
1.3 Dialogue between a key and a PC
This action is subject to no specific rules (is always possible)
this action copies all parameters (when present, also the
program parameters [thermal profiles] and, if available, the
logging data).
WARNING! The key does not verify the congruence of the
data coming from a PC. The software in the
PC must be able to perform all tests necessary
to ensure the integrity and congruence of the
configuration that is to be transferred to the key.
Note: If the configuration in the PC has been copied from a
controller, the data are certainly congruent.
For this kind of dialogue, the key can be set to perform (or not)
a special service related to the protocol used by Ascon
Tecnologic instruments to transfer data through TTL interface.
All Ascon Tecnologic instruments (exception made for TLZ)
use ModBus protocol for all interfaces but on the TTL interface
they put 3 (FF) character before the standard string. These
characters are used by the instrument ro recognize the
"silence" between two strings and identify the beginning of a
new string.
By setting properly the dip switches, it is possible to obtain a
dialogue with or without the 3 additional characters (FF).
1.4 Dialogue between an instrument and a
PC through the key
In this action the key is used as a smart converter. The key
is able to perform two different conversions:
– TTL <-> USB allows the dialogue between ALL Ascon
Tecnologic instruments and a PC;
– RS 485 <-> USB allows the dialogue between a PC and an
instrument [Ascon Tecnologic or not] equipped with an RS485.
Also in this case the key can be set to filter or not the 3 (FF)
characters.
The "smart" definition not only shows the ability to add/
filter the additional FF characters but also the capability to
automatically manage the direction of the RS485 line.
Note: Also in this case, the key does not verify the congruence
of the data coming from a PC. The software in the PC
must be able to perform all tests necessary to ensure
the integrity and congruence of the configuration that is
to be transferred to the key.
