IL-NT-RD Wiring
IL-NT-RD can be connected to InteliLite-NT or InteliDrive Lite controller via RS232 or RS485
communication line. It is possible to connect only up to two remote displays to one master controller, if
they are using different communication COMs. It is not supported to connect two or more remote
displays to one communication line, e.g. RS485. It is possible to monitor only one master controller
from one remote display at the time.
Connection process
Remote display after power on automatically starts to search for any master controller connected. It
starts to search on COM1 from master controllers address 1 to 32 and later on COM2 from address 1
to 32. Remote display tries two communication speeds 38400 bps and 56000bps.
During this process is displayed text “Detecting…” on screen and progress bar below counts from 0 to
100%. This process takes approx. 10-15 seconds. Than is 5 seconds pause and process continues
again until compatible master controller is found.
Not supported types of controllers, not supported application, or controllers that are not properly
communicating are skipped during the search.
Controller type selection
IL-NT-RD automatically detects controller type.
Troubles with connection
There are few reasons why remote display cannot connect with master controller:
1. Not supported type of controller connected (E.g. IGS-NT, ID-DCU, IC-NT, IGS-CU, etc.)
2. Not supported firmware in master controller
3. Configuration table error in master controller
4. Wrong settings of setpoint COMx Mode in master controller
5. Wrong connection, wiring, communication fail
Direct RS232 connection
HW module:
IL-NT-RS232
Master controller settings:
ControllerAddr = 1..32
COM1 Mode = DIRECT
Up to 2 meters:
It is recommended to use our standard AT-LINK cable.

Up to 10 meters:
It is recommended to use standard Null-modem cable for local connection between controller and
remote display, although the three wires (TxD, RxD, GND) RS 232 connection is enough for direct
communication:
