Page 7: Overview
SDK Programming Guide. Deva Encoder Range Features The Deva037 and Deva001 range of 3 and 4 axis Incremental and Absolute Encoder Interfaces are designed to enable simultaneous reading of 3 or 4 encoders per card, using a PC based system. Thus, with four 4-axis cards installed, up to 16 encoders can be supported by one system (Deva001 only). -
Page 8: Facilities
Digital Readout A Digital Readout (DRO) displays all the common facilities of the Deva037. This enables users to quickly verify that the Deva037 is installed correctly and to make checks of the system without having to write their own software. -

Hardware Installation System requirements The Deva037 requires a PC computer with a minimum of one spare USB port and Windows10/ Windows8/ Windows7/ WindowsXP 32/64 operating system. Both 32 and 64-bit operating systems are fully supported. Limited Linux support is available but is not covered herein. -

The installation may then be tested using the supplied DRO program, which can be found on the USB stick at ‘X:\Gold CD Relxx\PC interface products\Deva037\Issue x.x\Windows\utils\Win xx’ (‘X’ and ‘xx’ will vary according to the PC setup and Deva software release). Open the DRO program and a display similar to Figure 3.1 will be seen. - Page 15 Deva037 USB Encoder Interface User’s Manual Software Installation Ensure the Deva supplied USB stick is plugged into a USB socket on the PC and select the ‘Install Driver’ or ‘Update Driver’ button.

Page 20: Input Signal Descriptions
Deva037 USB Encoder Interface User’s Manual USB Incremental Encoder Interface Hardware 4.1.2 Input signal descriptions The Ai & nAi, Bi & nBi inputs are differential pairs for connection to the A-phase and B-phase quadrature outputs of an incremental encoder. The Mi & nMi inputs are differential inputs for the channel marker signal. This function will latch the counter reading for the relevant channel, allowing an accurate reading of the position of a moving encoder to be made at a specific instant. -
Page 21: Usb Connection
Functional description The Deva037 is designed to interface up to three incremental encoders or linear scales to the USB bus. The functions are programmed via Deva’s proprietary interface Enclib and/or, where the device is to be used in a CMM application, a utility such as DevaCMMCtrl. - Page 22 4.2.4 Touch Probe Interface The Deva037 incorporates a touch probe input. This input provides the correct signal conditioning to allow a volt-free contact type touch probe to be used. The probe function works like the marker function but latches all three axis counters simultaneously. Unlike the marker function it operates asynchronously and hence does not require that the A and B signals be at a logic one level.
