Usb Communications - Mantracourt T24-BSi Technical Manual

USB
Connection to the base station will be either a captive USB cable (T24-BSu) or a USB socket B for connection using
a standard USB A-B cable (T24-BSi). There is an optional cable assembly for the T24-BSi to provide for a USB
connection while the device is still fitted to the ABS case.
To communicate with the base station the connected device must use the USB HID Device Class and support USB
2.0 full speed interface (12mbits).
The USB connection will also power the base station.

USB Communications

Using the Mantracourt T24drv.dll driver is the easiest way to communicate with the base station. However, if you
want to write your own communications software you will need the following information:
Vendor ID: 6017 (0x1781 hex)
Product ID: 2980 (0xBA4 hex)
Incoming packets are read from report 0 and contain 64 bytes of data. There will always be 64 bytes of even if
there is only a few bytes of valid data. These bytes will need placing into a buffer and your software will need to
detect and extract complete packets.
Outgoing data is written to report 0 and must always contain 64 bytes of data. Any unused bytes should be set to
zero.
Please note that 65 bytes of data are actually sent and received but the first byte indicates the report number so
this is always zero.
