Instructions Manual of Communication Interfaces MI485 / MI486 / MI488
After connection to power supply voltage, the Power LED indicates the presence of power supply, while the diodes on the ethernet
terminal indicate the presence of the ethernet network. If network is active, one LED is lit or is blinking (the left LED indicates 10
Mb/connection /activity, and the right LED indicates 100 Mb/s connection/activity).

SETTING
3.1
MI485
The MI485 communication interface does not need any setting for its operation; however, measuring instruments connected to
RS485 communication should be set. Measuring instruments connected to RS485 net should have different addresses set (when
purchased their address is 33). They should also have the same communication rate (at purcase it is 9600 bits/s). The MiNet
program is recommended for parameter setting..
3.2
MI486 AND MI488
Parameters for ethernet connection should be set for the MI486 and MI488 communication interfaces before the first application.
Parameters are set by means of the Deviceinstaller program. Its installation and description of settings are described in item 3.2.2.
The RS485 net connected to the MI488 interface should also be set. We recommend to set the net by means of the MI485 interface
and the MiNet program (see item 3.1). The programs for setting the interfaces are avaliable on the CD marked MI48x.
3.2.1
SETTING ETHERNET CONNECTION
The communication interface should have a unique IP address in the ethernet net. Two ways of assigning the IP are described
below.
