18 DATA COMMUNICATION FUNCTIONS
18.5 Transparent
The transmitting transceiver transmits over the Air when the data time elapses in the following way:
 If a baud rate of 19200 and 1 stop bit are configured for the PC and transmitting transceiver:
When a duration equal to or more than 1/19200 x 10 x 16 = 8.3 ms elapses
 If a baud rate of 9600 and 2 stop bit are configured for the PC and transmitting transceiver:
When a duration equal to or more than 1/9600 x 11 x 16 = 18.3 ms elapses
In an NXDN Conventional system and NXDN Trunking system, data is sent to the ID configured for Base ID Type and
Base ID. In an NXDN Trunking system, data which is equal to or less than 80 bytes is sent on a control channel, and data
which is more than 80 bytes is sent on a traffic channel.
The maximum data capacity for the receive buffer of the transmitting transceiver in order to receive data from a PC is
limited to 1024 bytes. If transmit speed and reception from a PC is unbalanced and the overflowing received data exceeds
1024 bytes, the excessive data will be ignored.
For Mobile, if the transceiver receives the 1024 bytes of data while the transceiver is configured for which the RTS and
CTS ports are available, the transceiver starts the flow control to an external device. (Refer to
Port on page 524.)
The transceiver can control not to overflow from the buffer the data sent from the external device as soon as the
transceiver has started the flow control, so that the transceiver can receive the 1024 bytes of data. In the RTS and CTS
ports, the data communications with an external device are controlled as follows.
RTS:
When the buffer of the transceiver for serial communications becomes full, the status of the RTS port will be low level
<8 V).
CTS:
When the status of the CTS port becomes low level <8 V), the serial data will not be sent from the transceiver
Transceiver Behavior
1
A device sends data to the transceiver.
The communication port of the transceiver assigned
"Transparent" automatically starts transmitting if the received data
size reaches 80 bytes.
The communication port of the transceiver assigned "Transparent
2 (NXDN)" automatically starts transmitting if the received data
size reaches 314 bytes.
"COMPLETE" appears on the transceiver main display for 1 sec
when the transmission completes, and the transceiver restores
the previous display.
