A.3 - PL01 Wiring Diagram
Channel A RS-232 (CHA_TX and CHA_RX) and Channel A TTL (TTL_TX and TTL_RX) are mutually exclusive
and operate at different voltage levels. Do not connect to both ports simultaneously. There are no TTL
signals available for Channel B. The two video lines are specifically routed to have the least impedance of
any payload lines; place any analog video lines along these payload lines.
