NUT（Network Update Time）、RPI（Requested Packet
Interval）這兩個參數(shù)在網(wǎng)絡中常常影響到網(wǎng)絡的帶寬，使得網(wǎng)絡不暢通或效率不高。在理論上來說當帶寬在60%~70%網(wǎng)絡效率較高，當帶寬不夠時就應該減少NUT與RPI時間。另外NUT，RPI之間按一定的關系來確定數(shù)值，也能提高網(wǎng)絡效率減少帶寬，即RPI=2nNUT。

3．安裝
除了軟件設置，安裝不合格同樣會引起很多問題。

敷設ControlNet網(wǎng)絡的RG6電纜保護要做好。電纜破損，分支器進水以及BNC頭做得不好都將影響網(wǎng)絡的暢通。在網(wǎng)線敷設好后，分支器不聯(lián)入節(jié)點，裝上終端電阻，測量分支器聯(lián)入節(jié)點的BNC芯線與外層電阻應在37.5 ~43Ω之間，小于37.5則有短路現(xiàn)象，過大則接觸不好。BNC頭的制作建議使用1786-CTK工具制作，在工具箱內光盤中有制作的全過程的影像文件。
