Talk:Turn-around-times

In network configuration system of PLC using PC/PPI, The cable is in transmit mode when data is transmitted from RS-232 port to the RS-485 port. The cable is in receive mode when it is idle or is transmitting data from the RS-485 port to RS-232 port. The cable changes from receive to transmit mode immediately when it detects characters on RS-232 transmit line. The cable switches back to receive mode when the RS-232 transmit line is in the idle state for a period of time,it is defined as Turn-around time. The time depends on the baud rate selection. --202.146.241.9 03:05, 6 November 2005 (UTC) yudhaa@mobile-8.net
