I'm making use of STR711 Microcontrollers for my Final Year Project at university. I decided on using RIDE, and as a result ordered what I thought was the RLINK STD in-circuit debugging & programming tool from a third party vendor. Due to some confusion, however, I ended up receiving an older version of RLINK that came with a 14 pin JTAG adapter as opposed to the 20 pin adapter required by STR7's, and software support only for 8051 family of microcontrollers.

While I was able to download the version of RIDE with support for the STR7 from this website, I am still in a spot of bother when in comes to the JTAG adapter. Bearing in mind that it may be difficult to return this adapter, I would like to enquire whether it is at all possible to convert a 14 pin JTAG adapter to the 20 pin one required. From what I've seen of the pinouts for 14 and 20 pin JTAG, it appears that the only extra pins in the 20 pin model that are used are related to debugging such as DGBRQ. I was wondering whether it would be possible not to implement these functions and use the required pins for an STR7 from the 14 pin JTAG adapter.

Thanks in advance
