Connection for E5ZN Compoway-F Communications

The figure below shows the connection between one PRT1-SCU11 and 1 to
15 E5_N Temperature Controller units. Refer to the E5AN / E5CN / E5EN and
E5GN User Manuals for more information on Wiring.

This way of communication also allows the use of other stand-alone Compo-
way-F instruments, for example a K3GN Digital Panel Meter.
Note The E5AN / E5CN / E5EN and E5GN support baud rates of 9.6 and 19.2
kbits/sec. Ensure that the PRT1-SCU11 baud rate setting (DIP-switch 1 and
2) is set to the correct setting.
The E5ZN Temperature Controllers use Compoway-F communications over 2-
wire RS-485. Multiple E5ZN units can be connected together, using one RS-
485 Terminal. The RS-485 connection is extended through the E5ZN sockets.
However, these units all have unique RS-485 addresses.
The RS-485 connection can be either one-to-one or one-to-N. Up to 15 E5ZN
units can be connected in a one-to-N system.
The figure below shows the connection between one PRT1-SCU11 and 1 to
15 E5ZN Temperature Controller units. Refer to the E5ZN User Manuals for
more information on Wiring.
Note The E5ZN supports baud rates of 9.6, 19.2 and 38.4 kbits/sec. Ensure that
the PRT1-SCU11 baud rate setting (DIP-switch 1 and 2) is set to the correct
setting.
