such as PLL lock, Power-Up, stabilizing Power, and etc. So, it will degrade overall
system performance. Usually, the SD-170E series uses at least 20ms (Default).
f. Tx Delay Time 2
This is the required time to detect tone, and is only available for the FFSK Modem
and channel with Tone (CTCSS/DCS). In case of SD-170E series, 250ms (Default) is
recommended.
g. Number of Allowable Errors for Start Bit
This option prevents the radio from receiving invalid data by an external
disturbance. Consequently, the more unwanted signal the radio receives, the less
selectable value you may select.
6.4. System Option 3
a. Tx Off Delay
If all assigned data is transmitted, after the transmission the Radio keeps the TX
status during this period of time, TX stops. Normally, in case of the SD-170E series,
0ms (Default) is recommended. Detailed information is given in Section 5.2.
b. Tx On Delay
Radio transmits data after elapsing this period of time since TX starts. In case of
the SD-170E series, 20ms (Default) is recommended. Detailed information is given in
Section 5.2.
c. Rx On Delay
The radio enters RX status after elapsing this period of time since receiving the
carrier. In case of the SD-170E series, 16ms (Default) is recommended. Detailed
information is given in Section 5.2.
7. Modem Operation Explained
This section explains each operating mode and details the modem serial pin connections.
There are two types of modes, Auto and Dumb mode. In Auto mode, the radio is
automatically controlled by existence of inputted data from a DTE. To avoid data
overflow by limitation of the buffer memory due to continuous input, serial port data
flow is controlled by the radio in communication with a DTE. In Dumb mode your
application should control all these processes such as Tx preparation for the RF stage
