[RC232] What are the LEDs for? They are not included In the RC2500 datasheet They are not in use for –RC232 protocol but is used with Tinymesh protocol, so for –RC232 they do not need to be mounted. Last Update: August 8, 2017 January 25, 2017 1493 RC232 Q&A Related Knowledge Base Posts -[RC232] “we are building an application with one master boat, which communicates with 150 slaves boats (obviously in open sea). Each slave boat will have a bit rate of 1Kbps to the master boat, the signal range must be till 2km. We are considering using RC17xxHP-RC232 modules to communicate with master boat and slaves. Our questions are: It will be the RC1780HP-RC232 module suitable for this application, or you propose some other module? It’s possible with this device to create a multipoint network (one master, many slaves)? Does your modules have frequency hopping function? “[RC232] “The data rates for the high speed module RC1180HP is more suitable for our needs, but we need to have the possibility to increase the range with a high gain antenna or any kind of amplifier, could that be possible? “[RC232] What is the estimated range on 433mhz @27db 19.2kps, 868mhz @27db 19.2kps?
