About this manual
The N-COM is a dimming control system designed for the Nottrot N-Line models. Since all models are built using the same
concept (similar components), all data has been collected to create one manual that describes the entire series.
This document contains technical and users information about the dimming system and must be used with the manual of your
type of monitor, like N-Line. Please make sure you are using the latest version of this manual when installing the product.
Although we strive to be as complete as possible, there will always be additions made. All updates of this document are subject
to change without notice. The revision history is shown in chapter 1.

1Introduction
N-Com is an advanced dimming system on the N-Line. This digital system can be used for controling various functions like OSD-
control and dimming of your LCD monitor. N-Com also makes it possible to interconnect upto 18 monitors for central dimming
and (basic) control. The units will be addressed automatically.
➔With the N-COM application software you are able to set all kinds of parameters descibed in this manual.
The advantage of the N-Com with LIN-Bus and RS485 is the supported long cable length. It supports auto-addressing and
patching of any dimming control-unit to any other monitor.
Safety precautions
•Consider this document as a addendum on the N-Line monitor manual.
•Remove power before (dis)connecting any cables to the monitor
•Connecting the RS485 (LAN/CAT5) cable to a computernetwork may result in damage to the devices on the network and
the monitor.
•The cover glass or touch sensor is made of regular (or hardened) glass. This can be scratched or even broken in pieces by
hitting it
•In case of trouble contact your supplier. Service should only be done by qualified personal
•Never open the chassis. There are no user-serviceable parts inside.
•Never place any parts of the monitor system near warm objects like heaters or in direct sunlight.
•Keep all parts dry to avoid short circuit. Make sure no fluids can enter the units through any ventilation gaps.
•Wait for at least 6 seconds after switching power off before removing the cables.
•Make sure the temperatures do not exceed max values when storing or using the display.
•Never expose the unit to strong vibrations during transport and use.

2System overview
Basically N-Com is introduced for advanced dimming of the N-Line monitors. With this system you are able to control OSD and
dimming levels from the front of the monitor, but you can also control it remotely with a NControl, PLC or PC by means of RS-
485 (using a USB adapter cable) or with a LIN-Bus dimming knob. LIN bus (Local Interconnect network) is a serial network
protocol used for communication between components (Single wire / 12VDC). In this chapter the harware configurations will be
described.

Connectors at I/O bracket
For connecting the units to a controller and daisy chain, there are 2 connectors located on the I/O bracket.
→The RJ45 connectors are not compatible with LAN protocol.

4Addressing for dimming and commands
4.1 NET ID and Unit numbers (ID)
NCOM uses auto addressing (NET-ID =logic address), which ensures that you always have access to the entire network. Even
though there are duplicate unit numbers in use. The first unit (monitor or NControl*) in the chain is assigned logic address 1 and
acts as master for the chain.
It is also possible, without additional settings, to add peripheral equipment such as Ncontrol and VariCap. A user who does not
use the advanced functions such as control with the PLC will not notice a NET-ID. The NET-ID is also used to exchange dimmer
data in a fast way, so that you have a nice smooth dimming function, regardless of the number of sources.
A unit number can be set by the user in the NCOM app. All commands sent by an external controller (PLC. PC etc) will be
distributed in the daisy chain by the master. A reply will always be given by the master, NET-ID1
*) NControl is a 4.3” touch screen device to control dimming and functions of the monitors in the chain.
→Notations: ❶=NET ID, ①=Unit Number, ⑴=Source
Example of a simple daisy chain with 3 monitors with and without a NControl:

Available unit numbers:
⓪Reserved for zero configuration
②-⑲Available for user
⑳Central dimming
㉑-㉓Reserved for NControl
㉔Reserved for VariCAP backlit Zones
Now that we know the structure of NET-ID’s and Unit numbers we can look at the way dimming and function control uses these
numbers.
→Dimming is based on Unit-sources and commands are based on logic addresses.
4.2 MultiDimming control setup
MiltiDimming is a term used for dimming monitors in many different ways using different dimming sources. MultiDimming is a
key-feature of the NCOM system and it ensures a very flexible way of dimming and function control. Dimming of a monitor can
be controlled by its own dimming knob, a dimming knob from another monitor or RS485 HEX-commands or a combination from
these.
Basically a monitor will follow a dimming level of a Unit Numbers-Source, notation ①-⑴. Per Unit Number upto 4 sources can
be set for dimming level.

5Protocol
The monitors can be controlled by an external RS485 command. The standard protocol is NCOM. As an option the monitor can
be set to use the SCOM protocol.
→The RS485 commands are actively forwarded by each monitor, like a repeater. An un-powered monitor will break the chain.
→The master (the first device in the chain) is the communication partner for the PC/PLC. A reply will always be addressed from
the master.
5.1 NCOM
Communication settings:
•RS485
•Half duplex
•Frame based
•Baudrate 115200 (→Do not change the original RS232 baudrate 38400 in the unit! )
•Data bits 8
•1 stop bit
•no parity
A message always consist of a start (0x02) and stop (0x03) byte, address to sent to, command, length of data bytes and
checksum. The length of data can be 0 to 79. See complete description and example in the NCOM-protocol Excel sheet (available
on request).
All commands and listed in: NCOM-protocol_x.x.xlsx, where x.x is version. Please contact us to receive a copy.
Checksum: sum all data in hex: 02+01+99+05+14+00+10+80+FF and inverse the byte, take lsb.
5.1.1 Dimming format
The data package for NCOM dimming has following format:
(fixed)
0x02=
02 startcode. Always 0x02
0x01 =
01 = master monitor. Always 0x01. The master processes all data from the PC or PLC and takes care the other units
also get these data. A reply is always sent to the PC / PLC! Do not send a new message before the reply is received.
0x99 =
command. Always 0x99 for external level
0x05 =
amount of bytes
0x14 =
unit number, in this case unit / monitor number 20 (HEX 14)
0x00 =
level source 1, level to be processed by each unit which listen to unit 8 , source 1. Dimming level is 0
0x10 =
level source 2, see source 1, but level 10(hex) 16(dec)
0x80 =
level source 3, see source 1, but level is 0x80(hex) 128(dec)
0xFF =
level source 4, see source 1, but level is 0xFF ( hex) 255 (dec) = maximum level
0xBB =
checksum: sum all data (byte 0..8) in hex: 02+01+99+05+14+00+10+80+FF and inverse the byte, take lsb.
0x03 =
end of frame, always 0x03. No part of checksum.

5.1.2 Function and OSD control format
Funtion control of monitors is based on logic addresses (NET ID). Function control is only available from the NControl and
external RS485 commands. The command is addressed to a NET ID in the chain. This command is distributed by NET ID 1
(master) to the slave units. The master will send a replay.
→Sending a command to any unit in the chain will always have a reply from the 1st unit, the master.
When a NControl is used in the chain, this will be the master. The 1st monitor in the chain will have NET ID 2
