CONFIGURATION
If the t r ansmitte r is al r eady configu r ed as r equi r ed by the application ( senso r
type, r ange, etc ) , it may be installed and used r ight away. Howeve r , if a
distinct configu r ation is r equi r ed, this can be done th r ough the TxCon f ig
so ft wa r e and the TxCon f ig In t e rf ace.
The TxConfig inte r face and softwa r e can be pu r chased f r om the manufactu r e r
o r at its autho r ized dist r ibuto r s and r ep r esentatives. Updates fo r the softwa r e
a r e available at ou r website. To install the TxConfig softwa r e, r un the
Tx_se t up.exe file and follow the inst r uctions.
The TxConfig inte r face connects the t r ansmitte r to the PC, as shown in
Fig. 1.
Fig. 1 – TxConfig Interface USB connections
Once the connection is accomplished, the softwa r e shows the configu r ation
options of the t r ansmitte r model attached. Access the Help fo r usage
inst r uctions.

The fields in the sc r een mean:
1. Inpu t Senso r : Choose the desi r ed tempe r atu r e senso r among the
available options. See Table 1.
2. Measu r ing Range: Defines the beginning and the end of the r ange.
When the Low Scale Limit is configu r ed with a value highe r than the
Full Scale Limit, the cu rr ent output will have a dec r escent behavio r
( 20~4 mA ) .
The values configu r ed in these fields can not be beyond the senso r
measu r ing r ange. The minimum span value has to be obse r ved as well
( see Table 01 ) .
