I-7561/I-7561U
The I-7561 is a cost-effective module for transferring serial data via USB. It allows you to connect your serial devices to systems that use a USB interface. Connecting the I-7561 to a PC, you get one RS-232/422/485 port. Like the I-7520A, the I-7561 contains “Self-Tuner” chip auto-tunes the Baud Rate and data format to the RS-485 network.The I-7561 module derives its power from the USB port and doesn’t need any power adapter.
