What are the advantages of acquiring potentiometer resistance via CAN communication?

The primary advantages are noise-resistant digital transmission and simplified wiring. While analog voltage transmission raises concerns about errors caused by ambient electromagnetic noise, CAN conversion enables highly reliable data acquisition. Additionally, since it can be built with 3-wire cabling, it significantly reduces complex wiring workloads in applications like forklifts and construction machinery.

What is the data update rate for CAN communication?

COCORESEARCH's RR series (CAN-compatible models) support high-speed updates as fast as 1 ms. Furthermore, because measurement data is automatically output to the CAN bus at each configured update interval, upper-level systems do not need complex command-response programming, contributing to reduced development costs.

Do you support the J1939 protocol used in automotive and construction machinery?

Yes, we have a proven track record of supporting the SAE J1939 protocol (DLC 8 bytes or less). Control data for steering angles and position information can be seamlessly integrated into standard in-vehicle networks. Customizations for individual specifications are also available upon request.

Can instrument settings and data backups be performed on a PC?

Yes, you can use our free dedicated software, 'LINKSHIP'. Equipped with a standard USB-C port, it allows easy management of setting values, report printing, and CSV-format data logging directly on a PC. Even when using multiple measuring instruments, copying master settings can significantly reduce workload.
