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
following is the block diagram if the parameters are configured as below.
Transmit Delay Time: 100 ms
Data Transmit Modulation Delay Time: 400 ms
Transparent Header: Enable

The DELAY frame is placed for the amount of the time configured for Transmit Delay Time and Data Transmit
Modulation Delay Time, and then the data is sent. There is no Gap Time between data blocks to be sent.
 Examples in an NXDN Trunking system
Example 1: If "Transparent" is assigned to a communication port
The following assumes that 250 bytes of Transparent Data are sent from a PC to the transmitting transceiver. The
data is sent on a communication channel as shown in the block diagram below.

The DELAY frame is placed between blocks of data to be sent (Gap Time) and the data is sent. 400 ms is fixed
value for the Gap Time in an NXDN Trunking system. 80 ms is fixed value for the Gap Time in an NXDN Trunking
system.
