864. I/O4.1 Introduction4.1.1 System IntroductionNUUO provides remote I/O solution for NVRmini/NVRmini 2 by connectingSCB-C31 with NUUO I/O Box SCB-C24/26/28. Refer to the below architecture,I/O device is connected directly with I/O Box, and input/output signaldelivered in RS485 format are converted to Ethernet through SCB-C31.NVRmini/NVRmini 2 can use the signals to do more sophisticated setup, suchas starting recording when input triggered, triggering output as an eventhappened, and much more.4.1.2 HW InstallationSCB-C24/26/28 must work with SCB-C31 (Ethernet-RS485 converter).Further, the C31 Box cannot be used for POS and converter at the sametime, and one C31 Box can be paired with one NVR unit only. Pleasefollow the steps below to configure the devices.Step 1: Check the system switch of SCB-C31 is switched to OFF-OFF position.Step 2: Connect SCB-C31 with power source.Step 3: Connect SCB-C31 with internet by RJ45 LAN cable.Step 4: Connect I/O Box with power source.Step 5: Connect SCB-C31 and I/O Box with cable, positive connection(TX+/D+ and DATA+) and negative connection (TX-/D- and DATA-). TakeSCB-C31 with I/O Box SCB-C24 for example as below.
