Does the Mini-ACE™ have a combined BC/Monitor mode?
A. No. The ACE and Mini-ACE™ do not include an explicit BC-MT mode. However, with the Mini-ACE™ bus controller mode, you essentially get a monitor for “free”. That is, in the ACE’s BC message block, all of the words of a message are stored: that is, the BC’s Command Word, the RT’s Status Word (including both status words for an RT-to-RT transfer), and any and all Data Words transmitted by the BC or the RT. In addition, the Mini-ACE™ will flag any error conditions: either failure of its own loopback test, and/or any no responses or errors in responses from RTs. So, in essence, you’re getting all the functions of a bus monitor with the ACE’s BC mode. Also, the Mini-ACE™ does include a combined RT/Monitor mode. In this mode, the ACE operates as a full-function RT for one RT address, and a selective message monitor for all other RT addresses. Q. We are using two Mini-ACE™s on two separate processor cards separated by a VME bus connection. We are trying to synchronize these two devices such
