Since all models are built using the same concept (similar components), all data has...

N-COM Setup manual 2 System 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 RS485 (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. Figure 2-1 System overview

N-COM Setup manual 4 Addressing 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...

N-COM Setup manual Available unit numbers: ⓪ Reserved for zero configuration Available for user Central dimming Reserved for NControl Reserved 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...

N-COM Setup manual 5 Protocol 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!...

N-COM Setup manual 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 Notes: To store data from RAM...
