2-7-2 RS-422 and RS-485

•

Mount the RS-422/485 Communications Unit on the E5ZE Serial Communica-
tions Model.

•

The E5ZE can be connected to the communications interface in the ratio of 1:N
with a maximum of 16 Units connected.

•

The maximum cable length is 500 m.

•

Refer to the E5ZE Multipoint Temperature Controller Communications Manual
(H77) for further details on communications.

Parameter Settings

•

Specify the following parameters using the communications DIP switch. Al-
ways turn OFF the power before changing the switch.

•

Set the terminating resistance at both ends of the transmission path including
the host device. If terminating resistance is to be set at devices other than the
E5ZE, make sure that the total terminating resistance value of the transmis-
sion paths is at least 100

Ω

.

Wiring the Communications Terminal Block

•

Always turn OFF the power supply before wiring.

•

Wire the power lines and communications cables separately to prevent noise
interference.

•

Use crimp terminals or solder the wire ends when wiring the terminals.

•

Tighten the terminal screws to a torque of 0.59 N

m, or 6 kgf

cm.

•

Do not apply a force of more than 100 N or 10.2 kgf to the terminal screws.

•

Do not bend any crimp terminals after connecting them to the terminal screws
and tightening.
