Page 24: Functional Description
Principle of Data Acquisition The M36N is an automatic data acquisition system with up to 16 measuring digits. It is based on ANALOG DEVICES Inc.'s AD7634 chips. These are fast 18-bit A/D converters. The component uses a charge redistribution successive approximation register (SAR) architecture to achieve a conversion rate of more than 100kSPS (8,1µs total conversion time). - Page 25 Differing applications might require special adaptations of the M-Module applying to the source of the measured value. For this reason, input adaptation is not implemented on the M-Module itself but on a small additional PCB plugged on the M-Module. MEN Mikro Elektronik GmbH 20M036N00 E2 – 2009-07-27...

Page 26: Registers
Functional Description Registers The M36N has a sequencer, which stores the data coming from the A/D converter in a dual-ported RAM buffer. The measurement order can be determined by the user. The buffer has a size of 16 data elements. A data element is comprised of a measurement Data Register, an Address Register and a Configuration Register. - Page 27 If no external clock is available, this bit has to be set to 0. 0x60 Status Register ( ) (read) 15..8 7..3 IRQ BI Status of the IRQ bit Present status of the binary input MEN Mikro Elektronik GmbH 20M036N00 E2 – 2009-07-27...

Page 31: Maintenance
The voltage inputs of the DC/DC converters are protected by a fuse. This fuse is not intended to be exchanged by the customer. Your warranty for the M36N will cease if you exchange the fuse on your own. Please send your board to MEN for repair if a fuse blows. -
Page 32: Appendix
Serial Number MEN user documentation may describe several different models and/or hardware revisions of the M36N. You can find information on the article number, the board revision and the serial number on two labels attached to the board. • Article number: Gives the board’s family and model. This is also MEN’s order- ing number.
