18 DATA COMMUNICATION FUNCTIONS
18.5 Transparent
Example 2: If "Transparent 2 (NXDN)" is assigned to a communication port
The following assumes that 950 bytes of Transparent Data are sent from a PC to the transmitting transceiver. The
data is sent on a control channel as shown in the block diagram below. There is no Gap Time between data blocks
to be sent.

Example 3:
The following assumes that 80 bytes of Transparent Data are transferred from a PC to the transmitting transceiver.
The data is sent on a control channel as shown in the block diagram below.
In this example, there is no difference in sending data even if either "Transparent" or "Transparent 2 (NXDN)" is
assigned to a communication port.
