SVANTEK 977W User Manual
The view presented on the display for each
of three kinds of possible power sources is
different. The current battery voltage is
displayed together with its approximate
state (in graphical format).
When the instrument is powered from a set
of internal batteries the user should select
the correct battery type (
Alkaline
and
Rechargeable
). It is essential for the right
detection of the capacity of the battery
pack.
8.3. Setting the interface parameters - Communication Ports
The
Communication Ports
position
enables
the
user
to
select
active
communication
ports
(
GPS
and/or
Serial Port
) and programme them.
As a serial port the user may select
RS232
or
Bluetooth
.
<ENT>
For the
RS232
serial port, two parameters should be defined: transmission
speed (
Baud Rate
) and the time limit during which the communication
operation should be performed (
Time Out
).
Setting the transmission speed of the serial interface
The RS 232 interface transmission (
Baud Rate
) speed can be selected from the following available values:
1200
(bits/second),
2400
(bits/s),
4800
(bits/s),
9600
(bits/s),
19200
(bits/s),
38000
(bits/s),
57600
(bits/s) or
115200
(bits/s). The selection is made by means of the
◄ or ► push-buttons. The setting here should be the
same as the connected instrument or computer to ensure successful data transfer.
The other RS 232 transmission parameters are fixed to
8 bits for data
,
No parity
&
1 Stop bit
.
Setting time limit for the performance of serial interface operation
The default value of the parameter
Time Out
is equal to one second but this may be too short for the printers,
which may not be fast enough. In such cases, the
Time Out
parameter may have to be increased to a higher
value.
For the Bluetooth interface the user should
key in the
Authorisation code
to pair a PC
(or suitable tablet or smartphone) and the
instrument.
If the
Visible
parameter is switched on,
then during the searching of the Bluetooth
unit by the PC, the instrument will be visible
and it will be possible to pair the instrument
and
the
PC.
The
instrument
can
communicate with the PC also with inactive
Visible
parameter.
