User's Manual

Note that the Login command begins with an asterisk (*), and the Module’s address
is repeated twice. Prior to Login, no Module is active, and no character echo back
will be received on the PC. Example, to log into the Transmit Module (AR150):
Type: *log0202 (all of which is hidden because it is not echoed)
AR150TX [02] (this is what the Module sends to indicate successful login)
The information above echoed by the addressed Module is: the Module type
(AR150), the function (TX = Transmitter), and the hex address (02).
The LOG command will automatically make any other active Module Quit (logout) if
it was previously enabled.
4.3.2 TX Downstream Air Frequency
The Downstream Air center Frequency is set within the 5.8 GHz band with the
command:
DA<nnnn>, where the frequency is in Megahertz.
The DA command is acknowledged with an “initializing” message during the actual
writing of internal processor registers, and the successful completion is
acknowledged with the message displaying the new value.
It must be given to both the TX Module and the DX Module.
Example, to set the Downstream frequency to 5735 MHz:
*log0202 [this typing is not echoed, not shown on the PC screen, the active module,
seeing the login, will logout]
AR150TX[02]>da5735
Initializing...
DA Downstream Air Output 5735 MHz
The Downstream Air frequency is the actual frequency used in the 5.8 GHz ISM
band, as would be seen by a spectrum analyzer. It is received by the CPE outdoor
transceiver which connects to the subscriber cable modem.
The available 18 values are in the Section on Frequency Planning.
IMPORTANT: Downstream Air Frequency must be set in BOTH the TX and the DX
modules, separately.
4.3.3 TX Title
The Title, or label, for the Access Point TX Module can be set.
It can be up to 3 lines of alphanumeric text and keyboard printable ASCII symbols,
with 32 characters per line.
All three Modules can accept a Title.
T<n><string>, where n = {0, 1, 2}
Notice that there is no space between the single-digit line number <n> and the
<string>. If there is one space, it is thrown away. Spaces in the title are OK.
