1.2.10 Automatic Carrier Wave Output Option - AC
This option allows the TIMTER™ to transmit a carrier wave when the clock input is absent, which would normally
cause the RF output to be turned off.
1.2.11 Baud Rate Option
– BRx
The BR option changes the serial communications default baud rate on the transmitter to the one selected. A number
from 0-8 follows the BR option request. Corresponding values are as follows: 0 = 57600 (Standard default for all
Quasonix transmitters); 1 = 4800; 2 = 9600; 3 = 19200; 4 = 38400; 5 = 56000; 6 = 57600; 7 = 115200, 8 = 230400.
1.2.12 CP07 Control Protocol Option
– C7
The Quasonix interpretation of IRIG 106-17, Appendix 2-C serial control protocol (CP07) “provides standards for
commands, queries, and status information when communicating with telemetry transmitters configured with
communication ports.” The Basic command set contains the minimum (required) commands for transmitter control,
query, and status. The Extended command set contains optional commands that may or may not be implemented at
the manufacturer’s discretion. CP07 is enabled when the C7 option is requested.
The default baud rate for CP07 transmitters is 9600.
1.2.13 Convolutional Encoder Option
– CE
The CE option enables convolutional encoding and NRZ-M conversion. This encoding adds redundant information
to the transmitted data stream to help detect and correct bit errors that may occur, particularly due to predominantly
Gaussian noise. Use of convolutional encoding requires a matching Viterbi decoder in the receiver to extract the
source data. The encoded data rate will be twice the source data rate, and the occupied bandwidth will also be
doubled.
