Summit WM Controller diagnostics
Summit WM Technical Reference Guide, Software Version 5.174
Using the console port
Connect to the console port of the Summit WM20 Controller to perform diagnostics or a rescue
procedure. The Summit WM20 Controller does not directly expose a DB9 COM interface. Instead, serial
console access is provided through the USB Control port as a USB connection. The connector is reserved
for Serial-over-USB operation.
To connect to the console port:
1 Install the virtual serial driver by Silicon Laboratories Inc. on the laptop. You only need to install the
serial driver once. You do not need to repeat installing the software each time you connect to the
port.
2 The CP210x USB to UART Bridge VCP drivers are provided by Silicon Laboratories Inc. Depending
on the OS of your computer, click on the appropriate "VCP Driver Kit" link on the web page given
below. Note that this URL is subject to change.

3 With a normal USB (male A/B) cable, connect the B end to the Summit WM20 Controller and the A
end to the laptop. The driver recognizes the connection and installs a serial device (Com #).
To determine the actual number assigned to the device, navigate to Control Panel > System >
Hardware > Device Manager > Ports (COM & LPT).
4 Using a terminal program of choice (for example, Hyperterm) establish a connection to the Summit
WM20 Controller using the corresponding COM device.
The connection settings are 9600 8N1 no flow (9600 bps, 8 bits, no parity, 1 stop bit, no flow).
