Conv TTL Blocking
The TTL to blocking converter is a system designed to replicate TTL and blocking pulses. An incoming TTL pulse is replicated simultaneously on both the TTL and blocking channel on which it was received. Similarly, a blocking pulse on an input channel is replicated on both blocking and TTL outputs of the same channel. The system consists of two VME64x double height boards, the front module and the rear transition module (RTM). The front module contains all the active circuitry, whereas the RTM is passive and targeted for connectivity.
