Communications (TB302)
Terminal Block TB302 can be used for communications. The wiring for commu-
nications is easy when several 8-point Controllers are connected in parallel. The
screw size for the terminals is M3.

Terminal Connection
Do not tighten the terminal screws with excessive force. Each terminal screw is a
M3.5
×
8 screw. Use crimp-style terminals that are fit for the terminal screws. Be-
fore you connect PVC lead wires to the terminals, bare each lead wire 6 to 8 mm
from the end by removing the PVC insulation cover, and then apply solder to the
lead wire surface for a smooth connection.

-E specifications for the communications interfaces are the same
as those for 4- and 6-point controllers. Return to

Switch Settings
For the following switch settings to be effective, they must be made with the pow-
er to the E5ZD turned OFF, i.e., the switch status is read only when the power is
turned ON.
Unit Number: SW302
Each E5ZD-8
jjj
-E Temperature Controller is assigned a unit number to en-
able easy identification of the various Units during communications with the host
computer. The unit number (from 0 to F) is set using SW302. When multiple
E5ZDs are connected to the same host computer, the same unit number must
not be set for more than one E5ZD. The unit number is set to 0 at the factory.
Baud Rate: SW501
The baud rate determines the transmission speed for communications with the
host computer. The host computer must be set to the same baud rate as the
E5ZD for communications to be possible. Set SW501 to between 0 and 6 to set
the baud rate according to the following table. Do not set SW501 to between 7
and 9.

Set these pins to establish the type of sensor and the temperature range to be
used. Pins 4 to 9 are not used, so leave them OFF. All pins are set to 0 at the
factory, so the K setting will be 0
