C257

The Mod. C257 is a single width CAMAC module housing 16 independent 24 bit counting channels at a maximum input frequency of 100 MHz. The LAM is asserted by the 16th or 24th bit (programmable by internal jumpers) of each enabled channel. The status of the internal jumpers can be read via std. CAMAC functions. Each channel can be cascaded with the next one through internal jumpers. The unit exists in three different versions accepting respectively ECL (C257E), NIM (C257N) or TTL (C257T) inputs.
