This article takes the Protocol 103 for an example to explain how to upgrade the timing eye-call strategy to adaptive-call strategy in the actual programming, and provides a flow chart of transformation as well as the C source code.陈品富...
Multi-Drop - Usually, up to 32 devices can be connected per port, and even more using repeaters. Devices are distinguished by unique addresses that are assigned to each device. For example, if you have 5 devices attached to a port, they would be addressed as units 1 to 5. If you want...
In the example code, we use an array of RS485 addresses, to allow any arbitrary number of encoders to be used. uint8_taddresses[1]={0x54};//only one encoder connected, using default address of 0x54//uint8_t addresses[2] = {RS485_ENC0, RS485_ENC1}; //two encoders connected,...
1. Press the PUSH BUTTON (on side of receiver) until LED 2 flashes once, then release.2. Press the transmitter(s) to be programmed.LED 2 flashes with incoming RF.3. Wait 10 seconds until beeping and flashing of LED 2 quits, which indicates programming has ended. To delete ALL ...

New generation RS-485 transceivers have an improved feature that includes true fail-safe receiver inputs. This eliminates the need for pull-up/pull-down resistors as shown in the previous example. If a transceiver is specified to have a true fail-safe feature this means that, the differential...
