5 - Operating in a Linux Environment via USB

To open a USB connection to Mini-Circuits ZTM & RCM Series modular test systems, the

Vendor ID and Product ID are required:

 Mini-Circuits Vendor ID: 0x20CE

 ZTM Series Product ID: 0x22

Communication with the test system is carried out by way of USB Interrupt. The transmitted and received buffer sizes are 64 Bytes each:

 Transmit Array = [Byte 0][Byte1][Byte2]…[Byte 63]

 Returned Array = [Byte 0][Byte1][Byte2]…[Byte 63]

In most cases, the full 64 byte buffer size is not needed so any unused bytes become “don’t care” bytes; they can take on any value without affecting the operation of the system.
