weeder(1)                                    Qualcomm Atheros Open Powerline Toolkit                                   weeder(1)

NAME
       weeder - Weeder Solid State Relay Module Controller

SYNOPSIS
       weeder [options] [attenuation]

DESCRIPTION
       Set  or get the attenuation level on the Qualcomm Atheros Production Test System using a local RS-232 communication port.
       Attenuator settings are changed if an attenuation value is specified.  Attenuator settings are read and displayed  if  no
       attenuation  value  is specified.  The serial port settings must be configured before running this program.  Settings are
       9600 baud, no parity, 8 data and 1 stop bit.  See datasheet http://www.weedtech.com/wtssr-m.pdf for more information.

OPTIONS
       -e echo
              Enable or disable echo mode.  The value of echo can be 1=on or 0=off.  Alternately, keywords &quot;on&quot; and &quot;off&quot; can be
              used.  Atheros recommends that you always disable echo when using this program to speed relay switching.

       -m mode
              Turn  on  or off the Device Under Test power.  The value of mode can be 1=on or 0=off.  Alternately, keywords &quot;on&quot;
              and &quot;off&quot; can be used.

       -o units
              Change relay control module order.  Individual relay control modules are assigned a digital address  that  can  be
              referenced  using  the  UTF-8  letters  &quot;[A-P]&quot; then &quot;[a-p]&quot;.  The Atheros PTS is configured so that module &quot;B&quot; is
              activated before module &quot;A&quot;.  This options lets you specify some other module order.  The default value is &quot;BA&quot; to
              indicate &quot;B&quot; before &quot;A&quot;.

       -p port
              The  name  of  the  serial  port.   On  Linux, the name is usually &quot;/dev/ttyS[0-4]&quot;.  On OS/X, the name is usually
              &quot;/dev/cua[0-4]&quot;.  On Windows, the name is &quot;com[0-9]:&quot;.  The default is &quot;/dev/ttyS0&quot; on Linux and &quot;com1:&quot;  on  Win‐
              dows.   If  environment  string  &quot;WEEDER&quot;  is defined then it takes precedence over the default serial port.  This
              option then takes precedence over either default.  Belkin USB-to-serial cables are named &quot;/dev/ttyUSB0&quot; on Linux.

       -w wait
              Wait time in milliseconds.  Serial I/O operation are slow and a  delay  is  needed  after  each  write  operation.
              Unfortunately,  different  operating systems require different wait times.  This options lets you adjust the time.
              The default is 10 milliseconds which should be adequate on most systems.

ARGUMENTS
       attenuation
              The attenuation in decibels.  The attenuation may be expressed in decimal,  binary  or  hexadecimal  when  setting
              attenuator but is displayed in decimal when reading the attenuator.  Binary values start with &quot;0b&quot; and hexadecimal
              values start with &quot;0x&quot;.

EXAMPLES
       The following example turns the Device Under Test power on and configures the attenuator for 72db attenuation.  Option -m
       is not necessary if the Device Under Test power is already on.

          # weeder -m 1 72

       The  next  example  configures  the controller for 42db attenuation.  There is no needed to turn the Device Under Test on
       again because it remains on until turned off.

          # weeder 42

       The next example configures the controller for 56db attenuation and turns the Device Under Test off.

          # weeder -m off 56

       The next example displays the current attenuation on the console because no attenuation value was specified.

          # weeder
