Report
The Report option lets you choose to report the activity of all targets, approaching targets, or receding targets.
During the first minute after power up, the SI-2 will report all targets regardless of the selection above. This
allows you to test the unit with a tuning fork.
Baud Rate
You can set the Baud Rate option to 19200, 9600, 2400, or 1200 to match the speed of the device the unit is
connected to.
Direction Report
If you want to report the target's direction, click the Direction Report check box. + (toward), - (away) or ?
(unknown) will appear in the <D> field in the Tx String. If you don't check the box, nothing will show up in the
<D> field .
Tx String
The Tx String pull-down menu lets you pick the format in which you want the reported speed to show. The
following are represented in the Tx String:
8N1 <D> <ASCII hundreds> <ASCII tens> <ASCII ones> <CR>
8N1 <D> <ASCII S> <ASCII tens> <ASCII ones> <CR> <7-bit checksum>
8N1 <D> <ASCII hundreds> <ASCII tens> <ASCII ones> <.> <ASCII tenths> <CR>
8N1 <D> <ASCII *> <D><ASCII hundreds> <ASCII tens> <ASCII ones> <.> <ASCII tenths>
<,> <3 ASCII characters representing received signal strength in dB 000 through 225> <CR>
<LF>
8N2 <D> <ASCII hundreds> <ASCII tens> <ASCII ones> <,> <ASCII 0000.0> <CR>
8N1 <D> HEX [2][84][1][SPEED][1][AA][3]
D = optional direction indicator (+, -, or ?)
A = target amplitude in dB
Poll String
The Poll String pull-down menu lists the available formats that you can use to request a speed update from the
SI-2. It is only enabled when you select Update When Polled as the Rate of Update.
After making your selections, click OK. A dialog box will come into view that says Configure Completed, as
Figure 6 shows. Then click OK and remove power from the SI-2 device.
Figure 6 This dialog box indicates the SI-2 has finished configuring.
