To connect your meter to the PC use the optional HI 920010 (available
from your Hanna Dealer). Make sure that your meter is switched off
and plug the connectors, one into the meter RS 232C socket, the other
into the serial port of your PC.
Note: Cables other than HI 920010 may use a different configuration,
in which case, communication between the meter and the PC
may not be possible.
SETTING THE BAUD RATE
The transmission speed (baud rate) of the meter and the external
device must be identical. The meter is factory set to 2400.
If you wish to change this value, please contact your nearest Hanna
Center.
SENDING COMMANDS FROM PC
With terminal programs such as, for example, Telix
®
, Windows Termi-
nal
®
, it is possible to remotely control your Hanna Instruments bench
meter. Use HI 920010 cable to connect the meter to the PC, start the
terminal program and set the communication options as follows: 8, N,
1, no flow control.
Command Types
To send a command to the meter the scheme is:
<DLE> <command> <CR>
This line makes the computer send a Data Link Escape character (/ or
?), the command expressed as a number or a 3-character sequence
and a CR character.
Note: Windows Terminal
®
and all the other terminal programs that
support the ANSI escape sequence, represent the DLE character
by the string ‘^P’ and the CR character by the string ‘^M’.
