3--3 Key Operation
Before attempting communications when using RS-232C, RS-422, and
RS-485 Models, set the baud rate (communications speed) and Controller
number according to the following procedures; use the keys on the front of
the Controller to make the settings. For operation procedures other than the
following, refer to the operation manual supplied with the Controller or the
operating procedures listed in the datasheet.
The E5AF/E5EF goes to display level 0 when power is turned on. The display
level changes when the level key is pressed for two seconds or more. The
displayed contents at each level are shown in the following diagram. The
baud rate and Controller numbers can be set at display level 2.

Controller Number ( ): This setting assigns a Controller number (inte-
gers from 0 to 99) to each Fuzzy Temperature Controller to allow the host
computer to distinguish one Fuzzy Temperature Controller from the others in
the same system during communications. When
appears on the pro-
cess value display, use the Up Key or Down Key to input a set value. The
Controller number is set to 0 before shipment. Do not give identical Controller
numbers to Fuzzy Temperature Controllers in the same system, as this will
interfere with communications.
Baud Rate (
:!
): This sets the speed for communications with the host com-
puter. When
:!
appears on the process value display, use the Up Key or
Down Key to input a set value. The rate is set to 9600 bps before shipment.
The baud rate can be set to 150, 300, 600, 1200, 2400, 4800, or 9600 bps.
The set value becomes effective only after the E5AF/E5EF power is switched
off once and then on again.
