Page 36: Getting Started - Software
4.0 Getting Started – Software The following sections detail how to create software to interface to the uX communications interfaces. RS-232 The RS-232 interface makes use of a standard ‘command/response’ communications protocol. See section 5.0 for the syntax of the serial interface protocol. -
Page 37: Enabling Communications In C# For Rs-232
4.1.1 Enabling Communications in C# for RS-232 Communications in Microsoft Visual C# are started with the COM port initialized and then the port opened. Then a routine would be created to send commands out the COM port, and another routine to receive responses from the port. - Page 38 The application can be set to either default to a specific COM Port or the End User can be allowed to choose one for the particular PC. After initial configuration the following could be an example C# code routine to set up a transmit array, to build and send out a message to the COM port.

Page 41: Usb
The uX presents itself to the Host computer as a Human Interface Device (HID). In HID devices, the attached device instructs the host computer what the report format looks like via a “Report Descriptor”. The uX defines only a single write and a single read report type. -
Page 42: The Spellman Hid Communication Dll (Usb_Dll.dll)
Note the VID (Vendor ID) of VID_1200. This is Spellman’s assigned VID. 4.3.2 The Spellman HID communication DLL (USB_DLL.dll) Spellman provides a .dll (dynamic link library) to help communicate with the uX via the Windows driver. This file is named “USB_DLL.dll” and is included on the CD that comes with the uX unit. -

Page 53: Response Overview
Response Overview The command responses will follow the same format as outlined above in section 6.1. This list is comprised of Commands with complex responses only. Commands using a simple response will use the <$> character (ASCII 0x24) as a “Success” response or a single character error code. These responses will be eight ASCII characters in length. -
Page 54: Command Descriptions
Command descriptions This section gives descriptions of all available uX commands. Note that the examples given in this section include the checksum byte. The checksum byte is used for serial RS232 and USB communication, but not for Ethernet. If you are using Ethernet omit the checksum “<CSUM>” byte in your commands and response. -
Page 55: Program Kv Setpoint
Note: When this command is sent via the serial port the actual baud rate change does not occur until a delay time of 200ms has expired. This is to allow time for the response to be sent at the old baud rate. The host must wait for a minimum period of 200ms before sending new commands at the new baud rate. -
