2.1.7.ACK/NAK Protocol

Once this protocol is activated, the decoder waits for an acknowledgment from the host system:

•ACK (06 hexa) means: message correctly received by the host system.

•NAK (15 hexa) means: message incorrectly received by the host, upon reception of this character the decoder resends the message.

2.1.8.XON/XOFF Protocol

Using this protocol, the host system can control the data flow coming from the decoder:

•XON (11 hexa) means: host system ready to receive data.

•XOFF (13 hexa) means: host system busy, the decoder stops the transmission and waits for an XON.

2.1.9.RTS/CTS Protocol

This protocol is a hardware "handshake" between the decoder and the host system. Before transmitting data, the decoder rises its RTS signal (pin 4) to +10 volt and waits for a +10 volt signal on its CTS (pin 5) from the host. The rest position of the two pins is -10 volt.
