COM2
For the purpose of configuring the controller's operating parameters,
communication will be accomplished via the auxiliary communications
interface, COM2. This auxiliary interface only communicates via
RS232 and is reserved for configuring and updating the operating
parameters and for updating the firmware in the controller. For
example, with the correct hardware dip switch settings, the COM2
interface can be used to configure the parameters of the COM1
interface. The electronics of this interface are also optically isolated
from the other circuits of the controller.
The communication options for the COM2 interface follow:
Table 4-3:
Baud rate
1200, 2400, 4800, 9600,
19200 bps
Number of Data Bits 7, 8
Parity Even, Odd, None
Handshake None, Xon/Xoff
The default configuration parameters for COM2 are:
Table 4-4:
Baud rate 9600 bps
Number of Data Bits 8
Number of Stop Bits 1
Parity None
Handshake None
Digital Board DIP Switch
The digital board is mounted inside the LRP2000 enclosure closest to
the wall with the cable entries. The first 5 switches of the main board
set the COM1 baud rate, electrical interface, and the download
options for COM2. SW6, SW7 and SW8 are not used and should
remain OFF. When switch 1 and 2 are both set ON, the baud rate is
set via the Configuration Menu. The table below illustrates possible
combinations of switch settings for typical applications.
