I-7560U
The I-7560U adaptor provides a Windows serial COM port via its USB
connection and is fully compatible with both current and legacy RS-232
devices. The I-7560U features a full set of RS-232 modem data and control
signals (TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI and GND) on its PC compatible
DB-9 male connector. It also features a high-speed transmission rate of 921.6
kbps and is powered from the USB bus, meaning that no additional power
supply is required.
I-7561U and I-7563U
The I-7561U/I-7563U module is a cost-effective solution for transferring serial
data via USB allowing serial devices to be connected to systems that use a
USB interface. By connecting the I-7561U/I-7563U module to a PC, a single
RS-232 or RS-422/485 port can be accessed. Both modules contain a
"Self-Tuner" chip that automatically tunes the Baud Rate and Data Format to
the RS-485 network. The modules are powered from the USB bus, meaning
that an additional power adaptor is not required.
The I-7563U is a USB-to-single channel RS-485 converter with a 3-way RS-485
Hub. Each channel contains discrete RS-485 driver IC, providing support for star-shaped wiring
network topology.
