Hi,
I am back. I was asked to work on PCB board for the last 2 weeks, so I did not have the chance to go over the suggestions.

To MadCow: thank you for the info.
I think I forgot to mention that I am using USART and I2C.
1. The USART is used to communicate between my board with PIC16F876A and RS-485 Devices.
2. The I2C is used to communicate between my board and the Main Frame (processing unit).
On power up, the Pic...
Hi,
I am using PIC16F876A to relay data from RS-485 devices multi-drop daisy chain configuration (one master – multiple slaves) by means of Asynchronous serial module to a processing unit by means of I2C bus module.
Hardware Configurations:
RS-485 chip PIC16F876A...
