MD485 RS-485 Multidrop Interface

3.1.3 Configuring the MD485

The MD485 is typically configured using the Device Configuration
(DevConfig) utility, which is included with PC400 and LoggerNet and can be
downloaded at no charge from our web site. Using DevConfig, you select and
configure the active ports and choose the communication mode (see Figure 2).
Changed settings are saved in Flash memory.

Alternatively, a Setup Menu can be accessed by connecting the MD485’s RS-
232 port to a PC running a terminal program such as Hyper Terminal

TM

or

Procomm

TM

(always 9600 baud, 8-N-1) and pressing the “Setup” button on the

MD485. Changed settings are saved in flash memory by selecting menu item
“7” as you exit the Setup Menu. If left idle, the Setup Menu will time out 2
minutes after the last received character and exit without saving any parameter
changes with the message “Setup Timeout.”

A datalogger can remain connected to the CS I/O port while
setting MD485 parameters on the RS-232 port, although CS I/O
communications would be inactive until exiting DevConfig or
the Setup Menu.
