2.4 RS232 Interface
Computer commands sent over the RS232 interface simulate
pressing the front panel keys. Request stored data with commands
from Table 4 on page 14. The instrument then sends the requested
information to the computer. For commands to send data to the
Epson LQ-570+ printer see section 2.4.3 Downloading and
Printing Test Results.
2.4.1 Hardware Configuration
All RS232 connections are made through the Serial I/O port
located on the left side of the instrument panel (see Figure 1 on
page 4). Connect the 9-pin D connector of a computer interface
cable to the Serial I/O port on the instrument. Connect the
opposite
Serial I/O port (Com 1 or Com 2).
A command line may need to be added to the AUTOEXEC.BAT
file of your communication software to set up the connection. If
so, add the following command:
MODE COMn, 9600,N,8,1
Where n is the port number 1 or 2.
The BODTrak instrument is wired as Data Communication
Equipment (DCE) and operates at 9600 baud with 8 data bits, no
parity, and one stop bit. The pinouts of the necessary cables are
shown in Table 3 and Table 3. The receiving device (computer or
printer) must be able to continuously receive at 9600 baud or
characters may be lost during long transmissions.
