    ASCII C OMMUNICATIONS ESSAGE EQUENCING The master unit initiates all data transfers by either sending data to a slave or requesting data from a slave. This protocol is strictly half duplex; only one device may be transmitting at any time. A slave device should not transmit unless it receives a valid message that requires a response--when it does receive such a message, it must respond quickly (See Timing).
  • Page 76 “RTS” is high when the transmitter is enabled and low when the transmitter is disabled (“tri-stated”). The slave’s “FF” may be replaced with a one character time (10/baud rate) delay between transmitter turn-on and transmission of the STX. Time Limits...

If a message is received that has the same message number as the last message received, the recipient should acknowledge the message and then discard it.
