RP2.1 Tech Notes

Microcode mismatch after upgrade

TN0971

Product: RP2, RP2.1, RA16BA, RV8, RM1, RM2
Version: > v80
Date Added: 2016-08-02

Issue

After updating to v84 TDT drivers (or above) and updating the microcode on the devices in your system, zBUSmon will show a mismatch (red lettering) and indicate the version number is 80 for the following devices: RP2, RP2.1, RA16BA, RV8, RM1, and RM2.

Workaround

The latest microcode version for these devices is v80. You can still use the "Update All Devices" command to update your system's microcode. The microcode installer can detect the device types and install the correct microcode according to the device type. In this case, you can safely use both microcode versions in your system as needed. You will see a microcode mismatch indicator (red lettering) for devices using v80, but you can disregard the warning indicator in this situation.

Solution

Upgrade to the latest version of TDT Drivers. The mismatch indicator no longer erroneously appears for these devices.

RP2.1 DACs and ADCs will not function with v59b microcode

TN0189

Product: TDT Drivers, RP2.1
Version: 59b release 44 (before 08/02/2005)
Date Added: 2005-06-22

Issue

Installing TDT Drivers v59b release 4 (downloaded before 08/02/2005) and updating the microcode on an RP2.1 causes the DACs and ADCs to lose functionality. The RP2.1 will display properly in zBUSmon and it will load and run circuits, however no analog signal will appear on the outputs and no analog signal will be converted on the inputs.

Solution

As of 8/02/2005, the downloadable file TDT Drivers/RPvds v59b - release 4, available on the Downloads page, contains version 58 microcode for the RP2.1 module, which resolves the problem. If you are experiencing the problem, download the latest version of TDT Drivers/RPvds v59b - release 4, install the drivers, and reprogram the microcode on your RP2.1.

Connecting the RP2 or Stingray (RL2) to a video camera or VCR

TN0093

Product: RP2, RP2.1, RL2
Version: All
Date Added: 2001-03-01

Issue

This Tech Note describes how to construct a cable for connecting the RP2 or Stingray (RL2) to a video camera or VCR. This will allow you to use these devices to control recording and playback.

Solution

In the diagram below, the numbers listed under RL2 and RP2 indicate the pin numbers on the digital inputs and outputs that should be connected to the LANC connector.

The codes for controlling these devices are not published anywhere. Hobbyists have figured them out, and it may take some work to get them to work with the RP2 and RL2.

Channel one delay at 200 kHz

TN0061

Product: RP2.1
Version: Serial number < 2000
Date Added: 2002-12-09

Issue

When running a 200 kHz sample rate, analog input channel two is always delayed by one sample relative to analog input channel one. There is no delay at lower sample rates.

Workaround

Compensate for the delay by using a delay component on RPvdsEx or shifting the data by one sample.

Solution

This issue has been resolved in RP2.1s with a serial number of 2000 and greater, running RPvdsEx version 50 and greater.
