CHAPTER 6
COMMUNICATIONS
The analyzer communicates with a computer through its RS-232 port or its USB
port. The analyzer can also communicate wirelessly through its Bluetooth port, if it
is equipped. Only one port can be active at a time. The communication protocol is
as follows:
BAUD RATE: 9600 baud
DATA: 8 bits, 1 stop bit, no parity
HANDSHAKE: None
Communication is by ASCII characters only. Use a USB cable or 9-pin serial cable
to connect the analyzer’s serial port to the computer. The USB drivers must be
installed first. They are located on the ENERAC CD, and the ENERAC website:
www.enerac.com.
The analyzer’s RS-232 port is a DTE-type. Only three wires are necessary: pin 2 is
TxD, pin 3 is RxD, and pin 5 is ground.
A. ENERCOM SOFTWARE
You can retrieve current data and stored data from the ENERAC with any
communications program such as Windows
Terminal. You can, however,
considerably enhance the performance of the ENERAC by using the special
Enercom
TM
for Windows software. This software allows you to:
1. Monitor all emissions parameters simultaneously.
2. Record maximum, minimum, average and standard deviation for all
emissions parameters.
3. Set alarms for every emissions parameter including recording the time
duration that alarms have been exceeded.
4. Plot bar graphs and time plots of all parameters.
