GIR1002 FR / GIA1000 FR Connecting and Operating Manual Version: 4.03-3 page: 13
Description of characters used:
! :
ASCII-Code: 21H
This character interrupts a connection, if any is existing, and resets all GIR1002 FR devices
connected to their original state thus initialising a check to ensure that the following two
characters correspond to their respective device numbers.
Nr.:
Permissible range
“
0
”
to
“
9
”
and
“
A
”
to
“
F
”
(corresponding to ASCII code 30H to 39H and 41H to 46H)
As a precaution device number will be transmitted twice.
Data will not be processed by the GIR1002 FR unless the device number transmitted is identical
to the one set in the respective GIR1002 FR. If numbers are not identical the device will only
check if the data stream contains another
“
!
”
character thus indicating a new data circuit.
F1,F2:
Permissible range see table 1
Functional codes, specifying the parameter and/or value to be processed. For assignments
please refer to table 1 of chapter
‘
functional code
’
.
/:
ASCII-Code: 2FH
Indicates the end of a data transfer process. Each data transfer process, either from host to
GIR1002 FR or from GIR1002 FR to host is completed by putting
“
/
”
.
# :
ASCII-Code: 23H
Indicates the beginning of a data transfer process.
‘
#
’
is issued by the GIR1002 FR prior to starting transfer of data to the host. If the
character
‘
#
’
is transferred by the host after issuing of the device number, the GIR1002
FR device will know that data are to be transferred from the host to the GIR1002 FR
(programming of GIR1002 FR).
$ :
ASCII-Code: 24H
Signals that the data following will be transferred in hexadecimal code.
D1..D4:
Permissible range
‘
0

to
‘

’
and
‘
A

to
‘
F

.
(corresponding to ASCII code 30H to 39H and 41H to 46H)
Data will be presented in the hexadecimal mode. For more detailed information please refer to
chapter
‘

.
a :
ASCII-Code: 61H
Transferred as hand-shake signal by the GIR1002 FR after successful data input to
the memory.
