Connection to a Printer
To connect to a printer you must use a DTE to DCE (Data Communications
Equipment) cable.
Set the meter to the TALK ONLY mode by setting the HP-IB address to 31
from the front panel. Then set the RS-232 interface as the active interface.
See pages 187 and 189.
DTR / DSR Handshake Protocol
The meter is configured as a DTE (Data Terminal Equipment) device and
uses the DTR (Data Terminal Ready) and DSR (Data Set Ready) lines of
the RS-232 interface to handshake. The meter uses the DTR line to send
a hold-off signal. The DTR line must be TRUE before the meter will
accept data from the interface. When the meter sets the DTR line
FALSE, the data must cease within 10 characters.
To disable the DTR/DSR handshake, do not connect the DTR line and tie
the DSR line to logic TRUE. If you disable the DTR/DSR handshake, also
select a slower baud rate (300, 600, or 1200 baud) to ensure that the data
is transmitted correctly.
