SUB SERIES INTERVAL DATA RECORDERS
5 62-0342—01
Using the USB connection on your
computer
As an alternative to the SUB-RS232K converter, we offer the
SUB-USBK that allows you to convert the RS485 output from
your IDRs for direct connect to your USB connection on your
computer.
Baud Rate Selection
The communication baud rate is selected by means of a
jumper on the circuit board (See appendix C for location.)
There are three (3) selections: 19200, 9600 (factory default)
and 2400.
1. When using the IDR with a modem, the rate of 9600
should always be selected.
2. The baud rate on the IDR must always match the baud
rate selected in the E-Mon Energy software. Communi-
cation will not work if they are not set correctly.
3. After a baud rate change, press CPU Reset (See
Appendix C) to register the change in the IDR.
4. All IDRs in the “daisy chain” circuit must be set at the
same baud rate.
