1.1. Power Supply
USB-003 is powered through a USB port (Bus-powered). No external power supply
is required.
1.2. Block Diagram
Between USB and RS-485/422 are isolated.
2. Function
The driver IC built-in USB-003 supports RS-485 and RS-422.
By setting dip switch, USB-003 can support both RS-485 and RS-422.
This converter is that it has the dip switch to enable and disable the built-in 120
ohm terminal resistor and the echo cancelling function.

6. Latency Timer
In some cases, adjusting “Latency Timer” will help to speed up the response time of
application. The default value is set by device driver.
If you reduce the value of “Latency Timer”, its priority will be higher. But be careful
that the response time of the other applications will probably be slow.
Following steps of Windows OS show how to set “Latency Timer”.
Open “Device Manager” and right click “[USB-003/010/017…]”. Open “Properties”
window and open “Port Setting” tab, then click “Advanced” button.
