DETAIL OF LAN SCREENING

Screen

Up to 30* IAC 200/400/420/600s and 1000m

Controllers (including MIUs) on the main LAN and sub-LAN must not have conflicting

addresses. Controllers on different sub-LANs may use the same address. Ideally the sub-LAN

addresses should be kept within a range so as not to use up all of the main LAN addresses.

The number of IAC controllers on a Touch-screen
Sub-LAN is limited to a maximum of 31 base units
including the one the Touch-screen is plugged into.
Each Touch-screen can display up to 256
parameters.

ISOLATED
GROUND

LAN A and LAN B should be screened with the screen earthed only on a verified good earth at the computer or MIU.

LAN A and B screens should be connected to the isolated Ground Terminals of each of the IACs on the LAN - see Fig.8.

LAN A and LAN B should be screened with the screen earthed only on a verified good earth at the computer or MIU.

LAN A and B screens should be connected to the isolated Ground Terminals of each of the IACs on the LAN - see Fig.8.
