Wiring
The serial communications cable
attaches to the bath through the
DB-9 connector at the back of
the instrument. Figure 9 shows
the pin-out of this connector and
suggested cable wiring. In order
to eliminate noise, the serial ca-
ble should be shielded with low
resistancy between the DB-9
connector and the shield.
Setup
Before operation the serial inter-
face of the bath must first be set
up by programming the baud
rate and other configuration pa-
rameters. These parameters are
programmed within the serial
interface menu. The serial inter-
face parameters menu is outlined
in Figure 7 on page 38.
To enter the serial parameter
programming mode first press
"EXIT" while pressing "SET" and
release to enter the secondary
menu. Press "SET" repeatedly
until the display reads "ProbE".
This is the menu selection. Press
"UP" repeatedly until the serial interface menu is indicated with "SErIAL".
Finally press "SET" to enter the serial parameter menu. In the serial inter-
face parameters menu are the baud rate, the sample rate, the duplex mode,
and the linefeed parameter.
Baud Rate
The baud rate is the first parameter in the menu. The display will prompt
with the baud rate parameter by showing "baud". Press "SET" to choose to
set the baud rate. The current baud rate value will then be displayed. The
baud rate of the 7060/7061 serial communications may be programmed to
300,600,1200, or 2400 baud. The baud rate is pre-programmed to 1200
baud. Use "UP" or "DOWN" to change the baud rate value. Press "SET" to set
the baud rate to the new value or "EXIT" to abort the operation and skip to
the next parameter in the menu.
