Connection for E5AR/E5ER Compoway-F Communications
The E5AR/E5ER Temperature Controllers all use Compoway-F communica-
tions over 2-wire RS-485.
• The RS-485 connection can be either one-to-one or one-to-N. Up to 15
Temperature Controller units can be connected in a one-to-N system.
• The total cable length is 500 m max.
The figure below shows the connection between one PRT1-SCU11 and 1 to
15 E5AR/E5ER Temperature Controller Units. Refer to the E5AR/E5ER User
Manuals for more information on Wiring.
Note The E5AR/E5ER 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 cor-
rect setting.
