③ Caution/Note
In case data transmission (multi-transmission) by using COM1, COM2, do not set
the target to be transmitted equally. For example, if this is transmitted to FEP or
to HOST by both COM1 and COM2, collision may occurs during data process in
internal S/W.
-. FEP: Bi-directional communication signal system (connect to FEP)
-. HOST: Bi-directional communication signal system (connect to Environmental
Management Corporation’ s server)
-. SVR: Single directional communication signal system (one-way data
transmission)
-. OUT_1 ~ OUT3: Single directional communication signal system (one-way
data transmission)
Single direction mentioned here is of information flow. To make efficient
communication, control signals are exchanged. (e.g. ENQ, ACK, etc)
