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
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.
Setting Description Notes
0 Low speed Reduces current consumption
1 High speed Required for 230 KBaud and greater data port rate
(C)
REMOTE LED
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.
Setting Description Notes
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
becau
se they are constantly transmitting. Remote LED drives the Diagnostic port which has a small
amount of current draw.
