When a noise problem is shown to be helped by way of the High Noise option, chances are that the noise 
may be further squelched by use of a bandpass filter available for sale from FreeWave Technologies. 

MCU Speed controls the speed of the Micro Controller Unit in the transceiver. The default setting is 0 for 
low speed. A setting of 1 is required for Ethernet and UDP operation. 

The following table describes the MCU speed settings. 

0 

Low speed 

Reduces current consumption 

1 

High speed 

Required for 230 KBaud and greater data port rate 

This setting, when enabled, outputs LED information through the Remote LED pins on the data port. 
 
NOTE: This feature is only available with the 24-pin data interface. 
 

0 

Board LED’s 

Default, only on board LED’s are enabled.  

1 

Board and Remote LED’s 

Onboard LED’s are enabled as well as 
Remote LED’s through the Diagnostic port. 

2 Remote 

LED’s 

On board LED’s are disabled. Remote LED’s 
are enabled through the Diagnostic port. 

 
NOTE: When using Remote LED’s the center (TX) LED will not turn Green when in Setup mode. The 
Green TX LED has no remote pinout. 
 
NOTE: This feature may be used to save power in Multipoint Repeaters.  By turning off the on-board 
LED’s (setting = 2) the current consumption of the radio is reduced.  To reduce current consumption in 
Slaves, use the setting “Low Power = 1” (see p. 34).  Low Power does not work with Multipoint Repeaters 
because they are constantly transmitting.  Remote LED drives the Diagnostic port which has a small 
amount of current draw.
