6.2: CONFIGURING PCAP II PLUS FOR DIFFERENT BAUD RATES
This section is intended for advanced users, only.
The PCAP II Plus system is capable of operating at RS232 symbol rates of 9600, 14400, 19200,
38400, and 115200 baud. Each PCAP II Plus is factory-configured to operate at 115200 baud, which
works well for most modern PCs. However, some applications (such as modem or network links) may
require the use of a different baud rate.
Change the PCAP II Plus baud rate as follows:
1. First, reset the internal DIP switches of the external processor for the new baud rate as follows:
a. Power off the external processor and disconnect all cables, especially the EXTERNAL
POWER and RS232 cables.
b. Carefully remove the external processor top cover.
c. Locate the 5-position DIP switch at the front of the internal printed-circuit board. Set DIP
switch positions 1-3 to the desired baud rate as follows:
d. Replace top cover and reconnect all cables.
2. Next, configure the Master Control program for the new baud rate as follows:
a. Make sure that the external processor is powered OFF.
b. Power ON the computer (not the external processor) and load Windows. Run the PCAP II
Master Control program by double-clicking the icon; an error message should appear
indicating no communication with the box (it is powered off). Click OK and enter the
program anyway.
