For Systems with Maxon Radios

The VP satellite with Raveon radio requires a Field Interface Unit (FIU) with 

a Raveon radio (P/N FIU-2011DR) to communicate. If your current system, 

along with the FIUs, employs the (older) Maxon radios, the Raveon radio 

must be put into “bell202” mode for successful communication. 

Required Items:

•  Radio Manager software from Raveon
•  USB to Serial (DB9) cable with included drivers
•  12V Phoenix power connector (from authorized Toro distributor)
•  12V power supply for radio (from authorized Toro distributor)

To put the Raveon radio into bell202 mode:

1.  Disconnect all power to the controller. Remove the radio. Place it next to 

the Lynx computer on a static-free surface.

2.  At the computer running Lynx, install the drivers for the USB  

to Serial (DB9) cable. Reboot computer.

3.  Plug USB cable into a USB port and Serial port on radio (

Figure 1

).

4.  Connect Phoenix power cable into 12V power supply.  

Plug other end into DC IN port on radio (

Figure 2

).

5.  Plug in 12V power supply.

6.  Launch Radio Manager. See 

Figure 3

7.  Select appropriate COM port (

Figure 3, A

).

8.  Change the baud rate to 1200 (

Figure 3, B

)

9.  Press ‘Discover Radio’ button (

Figure 3, C

).  

The radio should be discoverd (

Figure 4

).

10.  At the command line, issue the following commands  

to the Raveon radio: 

ATMT 4

ATR2 15

ATBP 1

ATIO 7

TXTOT 60 

11.  To exit a Raveon radio from bell202 mode  

(to recommunicate with other Raveon radios,  

for example), issue the following commands:

ATMT 0

ATR2 3

ATBP 0

ATIO 0

12.  All interface board jumpers (both the satellite 

and FIU) must be set to the left, to the ‘VP’ 

side (see frame 1 on previous page).
