Cable specification
• Use a 4-core twisted and shielded copper cable (data transmission cable with
braided copper shield). The cable must meet the following specifications:
– Cable cross section 0.25 – 0.75 mm
2
(AWG23 – AWG18)
– Cable resistance 120
Ω
at 1 MHz
– Capacitance per unit length
≤
40 pF/m at 1 kHz
Suitable cables are CAN bus cables or DeviceNet cables.
