DEMO INFORMATION
Introduction
The NGC-
40
system is made up of six different modules, NGC-
40
-BRIDGE, NGC-
40
-HTC,
NGC-
40
-HTC
3
, NGC-
40
-IO, NGC-
40
-PTM and NGC-
40
-SLIM (Safety Limiter module that is required in European countries).

the modules and H# for the installation instructions. Refer to these instructions for more detail regarding the individual module.
NGC-40-BRIDGE Module
The NGC-
40
-BRIDGE module is the interface to the outside world allowing the NGC-
40
system to communicate with TOUCH
1500
software. The NGC-
40
-BRIDGE module has several communication ports, RS-
232
, RS-
485
and Ethernet. The NGC-
40
-BRIDGE also is the
module that gathers all of the information from the NGC-
40
-HTC/NGC-
40
-HTC
3
and NGC-
40
-IO. The method of communication between
the NGC-
40
-HTC/HTC
3
and NGC-
40
-IO is a protocol called Controller–area network (CAN or CANbus).
CANbus:
• Was designed to allow microcontrollers and devices to communicate with each other within a system without a host computer.
• Is a message based protocol, designed specifically for automotive applications but now also used in other areas such as industrial
automation and medical equipments.
• Is used in the NGC-
40
system to link the modules so that each module can communicate with any module in the system.
