The second parameter of the 

BAUD

 command (

abc

) is a 3-character block 

indicating how the data is formatted.

= Data bits (

7

 or 

8

)

= Parity (

N

 for None, 

O

 for Odd, 

E

 for Even)

= Stop bits (

1

 or 

2

)

NOTE:

7N1, 8O2, and 8E2 are invalid communication settings and are
not supported by the transceiver.

CTS [0–255]

The 

CTS

 (clear-to-send) command selects or displays the timer value 

associated with the CTS line response. The command parameter ranges 
from 0 to 255 milliseconds.

For DCE operation, the timer specifies how long to wait after the RTS 
line goes high, before asserting the CTS line. A timer value of zero 
means that the CTS line will be asserted immediately.

DECF [0–100]

The 

DECF

 (decrease frequency) is a local maintenance command that 

decreases both the transmit and receive frequency by the specified per-
centage of the adjustable range. This is a temporary setting until the 

RMST

 command is used to store the command.

DECP [0–100]

The 

DECP 

(decrease power) is a local maintenance command that 

decreases the transmit power by the percentage specified of the adjust-
able range. This is a temporary setting until the 

RMST

 command is used 

to store the command.

DF

The 

DF 

(decrement frequency) is a local maintenance command that 

decreases both the transmit and receive frequency by 1% of the adjust-
able range. This is a temporary setting until the 

RMST

 command is used 

to store the command. 

DIAGLEV [OFF, 1,2,3]

This command sets the diagnostics level used in the transceiver. 

OFF

 

indicates no diagnostics capabilities are available.

• Mode 1 (Standard Diagnostics) is indicated by 

1

• Mode 2 (Advanced Diagnostics) is indicated by 

2

.

• Mode 3 (Remote Maintenance) is indicated by 

3

Set 

DIAGLEV

 to the diagnostics mode currently used in the radio system.
