RS-232 Configuration
4.3 RS-232 Configuration
The Model 430 Programmer uses the following parameters related to the
RS-232 interface:
• Baud Rate: 115200
• Parity: No Parity
• Data Bits: 8 Data Bits
• Number of Start Bits: 1 bit
• Number of Stop Bits: 1 bit
• Flow Control: Hardware (RTS/CTS)
4.3.1 Serial Connector
An IBM-compatible computer’s serial port can be directly connected to the
Model 430 Programmer via a standard DB9-female-to-DB9-female null
modem serial cable. Refer to your computer’s documentation to determine
which serial ports are available on your computer and the required
connector type.
The Model 430 Programmer is classified as a DTE (Data Terminal
Equipment) device. It uses the standard DB9 male connector and identical
pinout used on IBM-compatible computers. The RS-232 connector pinout
for the Model 430 Programmer is fully documented on page 154 in the
Appendix.
4.3.2 Termination Characters
All commands and queries are transmitted and received as ASCII values
and are case insensitive. The Model 430 Programmer always transmits
<CR><LF> (a carriage return followed by a linefeed) at the end of an RS-
232 transmission. The Model 430 Programmer can accept <CR>, <LF>,
<CR><LF>, or <LF><CR>, or a semicolon ( ; ) as termination characters
from an external computer.
4.4 Ethernet Configuration
The Model 430 Programmer provides a 10/100Base-T Ethernet interface
as a standard feature. It complies with the IEEE 802.3u 100Base-TX and
802.3 10Base-T standards.
The Model 430 Programmer allows its IP address, subnet mask and
gateway IP address to be assigned either statically or dynamically. To
make these values static and assign them manually, set IP Address
Assignment to Static (see section 3.10.5.1) and then set the values using
