4 EVALUATION BOARD USB INTERFACE

The ZIC2410 has two UART interfaces, UART0 and UART1. UART0 is typically used for

general communication purposes, while UART1 is used to interface to the various software

tools (i.e. Device Programmer, etc.). UART1 can also be used for general communication

when not interface to the various software tools. On the evaluation boards either one or

both UARTs are present, when only one UART interface is present it will always be UART1.

The evaluation boards utilize a Serial-to-USB interface chip; as such the UARTs have USB

interfaces. The balance of this document will assume a UART1 connection; however the

procedures for installing drivers, etc. are the same for UART0 when present.

4.1 CONNECTING TO UART1 THROUGH USB

This procedure is written for an evaluation board however it applies to the ZIC2410USB-

WNA, as well. This procedure must be run for each component as it is connected to the

PC and powered on.

4.1.1 Enumerating the USB Drivers

When an evaluation board or other USB component is connected to the PC for the first time and

powered on, the PC will respond that it has detected new hardware. The following is the procedure

for enumerating the new hardware on the PC using the

‘Found New Hardware Wizard’

1) First, connect an evaluation board to the PC using a USB cable. Power the

evaluation board by placing the ‘POWER SWITCH’ in the ‘VREG’ or ‘USB’ position.

A LED should illuminate indicating that power has been applied to the evaluation

board. After a few seconds, the screen in Figure 3 should appear.

2) Either of the two choices given in Figure 4 will correctly install the new hardware onto

the PC, but the automatic installation will take more time because it must search for

NOTE: Before connecting an evaluation board to a PC via USB, install the CP210

USB Driver. For

installation information refer to Section 3 of this document.
