Problem
The BSC protocol is used by a master device to communicate with a slave device (station no. 4).
1. The master selects the device, in order to ascertain whether it can send data to the device. Give the select command sent by the master in ASCII as well as hex. Write down the transmission in the format etc. for ASCII and <55><10> etc. for hex. No need to show the .
2. The device indicates that it is ready to accept data, and the master now sends the following data: 1234 (ASCII). Write down the master's transmission (frame) in ASCII as well as hex. No need to show the . Make up your own BCC (checksum).
3. How is data transparency achieved in DF-1?
