RS-232C CONNECTION
2) Transmit the air leak tester settings data
(1) Set the air leak tester to RDY status.
＊ The RDY status can be confirmed by viewing the RDY signal from REMOTE.
＊ Communications will not take place other than in RDY status. If not in the RDY state,
input signals will be ignored.
(2) Transmit the settings value request to the air leak tester.
