3、485總線是一種最簡單、最穩定、最成熟的工業總線結構
這種概念是錯誤的。485總線是一種用于設備聯網的、經濟型的、傳統的工業總線方式。。其通訊質量需要根據施工經驗進行調試和測試采可以得到保證。485總線雖然簡單，但也必須嚴格按照安裝施工規范進行布線。
二、必須嚴格按照施工規范施工
在485總線系統施工時必須嚴格按照施工規范施工，特別應注意下面幾點。
1、485+和485－數據線一定要互為雙絞。
2、布線一定要布多股屏蔽雙絞線。多股是為了備用，屏蔽是為了便于出現特殊情況時調試，雙絞是因為485通訊采用差模通訊原理，雙絞的抗干擾性較好。不采用雙絞線是錯誤的。
3、485總線一定要用手牽手式的總線結構，堅決避免星型連接和分叉連接。
4、設備供電的交流電及機箱一定要真實接地，而且接地良好。有很多地方表面上有三角插座，其實根本沒有接地，接地良好可以防止設備被雷擊、浪涌沖擊。靜電累積時可以配合設備的防雷設計較好地釋放能量，保護485總線設備和相關芯片不受傷害。
