Table 6.1. Available Modem Baud Rate
In above cases, Modem speed is selectable.
6.2. System Option 1
a. Auto Mode
The radio will be automatically controlled by existence of inputted data from a DTE.
There is no need for the user to be concerned with operation of the radio. The
SD-160 will transmit simply by sending data.
b. Dumb Mode
The Radio should be controlled by user application, manually. For instance, to
transmit data, you should input PTT(RTS) signal besides assigned data. Moreover,
in control of the radio, exact timing should be defined by you. This mode is only
provided to give compatibility with existent radios.
c. TX Forcing Mode
During RX mode, when the Radio receives data from the DTE, if
TX Forcing Mode
Option is enable, the radio will transmit data. If disabled, the radio will not.
d. Initializing Data for HT (Hyper Terminal)
This is a strongly recommended option when using Hyper Terminal. In addition, you
can check the version of the modem.
