The following conventions are used to classify and explain the precautions in this manual. Always heed the information provided with them. Indicates information that, if not heeded, is likely to result in serious injury or loss of life. [. . . ] Description (1/2 W) E5ER E5AR 2 2 1 1 Use a 220 (1/2 W) terminator. RR+ Shield 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 correct setting. 26 Wiring the RS-422A / RS-485 Devices Section 2-3 2-3-6 Connection for R88A-MCW151-E Host Link Communications The R88A-MCW151-E uses Host link communications over 4-wire RS-422A. The figure below shows the connection between one PRT1-SCU11 and 1 to 15 R88A-MCW151-E units.

If the PRT1-SCU11 is connected on one end of the transmission circuit, the termination resistor must be enabled on the Unit, by setting Switch 2 to ON. The R88A-MCW151-E connected at one end of the transmission circuit, must also have its termination resistor enabled, by setting Pin 3 of DIPswitch SW2 to ON. The R88A-MCW151-E 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. 27 Wiring the RS-422A / RS-485 Devices Section 2-3 2-3-7 Connection for E5AK/E5EK K-Format Communication The E5AK/E5EK Intelligent Digital Controllers use the K-Format communications over either 4-wire RS-422A or 2-wire RS-485. Both are supported, through dedicated communication option units. Refer to the E5AK/E5EK User Manuals for more information on these dedicated communication units. RS-422A Connection to E5AK/E5EK The RS-422A connection can be either one-to-one or one-to-N. Up to 15 E5AK/E5EK units can be connected in a one-to-N system. The figure below shows the connection between one PRT1-SCU11 and 1 to 15 E5AK/E5EK Intelligent Digital Controller units. The table below shows the pin numbers used on the E5AK and E5EK units for connection of communication signals. Refer to the E5AK/E5EK User Manuals for more information on Wiring.
