TDS2CMA
The TDS2CMA module is an optional add-on module for the TDS1000 and TDS2000 series oscilloscopes, which provides Centronics parallel (printer), RS-232 serial, and GPIB ports. It was superseded by the TDS2CMAX and both are also backwards compatible with the TDS200 series.
These modules are not compatible with TDS1000B or TDS2000B series oscilloscopes which instead feature an integrated USB port for communications and storage purposes.
