1-4
Allow a wait time of at least 2 ms before the next command is sent after the host
receives a response from the E5CN/AN/EN-H.
Communications with the host are carried out through a standard RS-485
interface, RS-232C interface, or RS-422 interface (E5AN/E5EN-H). Use a
K3SC Interface Converter for RS-485, RS-232C, and RS-422 interface
conversion.
RS-485
• The RS-485 connection can be either one-to-one or one-to-N. Up to 32 units
including the host can be connected in a one-to-N system.
• The total cable length is 500 m max.
• Use a shielded twisted-pair cable with wires of a thickness of AWG24
2
(0.205 mm ) to AWG14 (2.081 mm
2
).
