Page 5: About Em2037
About EM2037 Introduction EM2037 is designed for OEM applications based on Newland`s image acquisition system. This high-performance decoded image engine can easily be integrated into various devices such as kiosks, ticketing machines and PDA's. The image acquisition interface, initial data interface as well as I/O interface are available for users, which enables users to easily realize second development via Newland`s SDK. -
Page 6: Electrical Specifications
Electrical Specifications Introduction The EM2037 Series are small decoded output engines that can read 1D and 2D bar codes and have image capture capabilities. The EM2037 Image Engine is specifically designed for easy integration into most existing applications. The decoder module supports a TTL level 232 interface which, in most cases, does not require any hardware modifications for integration. -

Page 18: Host Flex Circuit
Host Flex Circuit The host interface flex should be compatible with a CviLux Corporation CF20121V0R0-LF style connector, the following is an example of a flex circuit. Unit: mm Design Proposal Space for EM2037 and flex strip should be taken into consideration during structure design so as to avoid any extrusion on components of EM2037 or any damage on flex strip. -
Page 19: Depth Of Field
Depth of Field Introduction The depth of field is defined as the distance over which the EM2037 is able to resolve and decode a bar code symbol. This distance is referenced from the end of the EM2037 lens tube. All depth of field data is verified at T = 23°C (73°F), Vin=5V, ambient light = 300lux. -
