(12) Discrete signal input/output interface
(a) Time Mark Pulse Inputs (optional)
The two inputs, TMP1.1 and TMP2.1 are matched by a buffer circuit
(EVTA and EVTB signals) and are applied to the EVT inputs of the 2
TS25 circuits.
(b) Time Mark Pulse
The TMP1.0 output is generated by one of the TS25 circuits, after
storage and matching by a buffer.
(c) BT250F
The BT output of one of the TS25 is matched by a buffer and consti-
tutes the BT250 output, reserved for maintenance.
(d) Internal discrete inputs
Six signals internal to the RPU from PCBs Z1 and Z4 are applied to
an A/D converter, then to a 3-state buffer circuit, the outputs of
which are connected to data bus D (16/23).
