5. CONFIGURATION
All transmitters have a mini-USB type, serial connector, located on the instrument
side (Fig. 5.A), through which the instrument can be connected to a PC for
configuration parameters setup.
Connection is made by means of the special
RS45
(not isolated) or
RS45I
(isolated)
cable, which has a built-in USB adaptor and is supplied with a mini-USB connector for
the instrument plus a USB connector for the PC. For a correct connection, USB drivers
included in the
DeltaLog14
software package (the software can be downloaded from
the Delta OHM website) must be installed in your PC.
Attention
: the serial connection will not work if the instrument is directly connected to
a PC by means of a standard mini-USB/USB adaptor cable. For a serial connection,
you will need the special
RS45
or
RS45I
cable.
With the
RS45
cable, the instrument is powered directly by the USB port of a PC (at
least a 500 mA USB port is required), allowing in this way on-site instrument
configuration by means of a portable PC.
The PC can be connected even if the instrument has been already installed and power
supplied; the instrument is designed to avoid interferences between the two power
supplies. With the
RS45I
cable, the instrument is not powered by the PC USB port.

The instrument parameters setup can be easily performed by means of the application
program for PC
DeltaLog14
In such case, please refer to the software manual for
parameters setting.
The instrument can also be configured through the serial connection without the help
of the application program
DeltaLog14
, by using the serial protocol indicated in
section “COMMUNICATION PROTOCOL”.
In
HD45…S…
and
HD46…S…
models, the instrument setup can be performed
through a RS485 connection. See section “RS485 COMMUNICATION”.
HD46…DT…
models can be configured by means of the front keyboard, with no need
of PC connection. For keyboard setting, please refer to section “Configuration through
keyboard”.
The instrument continues to measure normally also when it is in configuration mode;
any analog outputs or relays are regularly updated for the measured values. Changes
made to parameters have an immediate effect (from measure cycle next to parameter
confirmation).
