Defaulting the Receiver to Factory Values
In the event that the user wishes to restore the receiver to factory values,
complete the following:
1. Remove the four screws from the bottom of the receiver and remove
the top cover.
2. Locate and press the small pushbutton on the circuit board labeled
DEFAULT.
3. The AC LED will flash once to indicate that the factory parameters
have been restored.
4. Replace the top cover and re-install the four bottom screws.
Setting the Receiver for Master Mode on the Serial Port
By default, the ProScale RF receiver is designed to operate as a slave device. In
this mode, a standard serial cable is used to connect the unit to a PC for normal
operation.
In some cases, it may be required to use the receiver as a master device to
communicate with another electronic product. To help to facilitate this, the unit’s
transmit and receive pins on the DB-9 can be reversed via internal jumper
settings.
To reverse the transmit and receive pins, complete the following:
1. Remove the four screws from the bottom of the receiver and remove the
top cover.
2. Move jumpers blocks JP3 and JP4 from pins 1 and 2 to pins 2 and 3 on
each jumper.
3. Replace the top cover and re-install the four bottom screws.
A male-male DB-9 serial cable may now be used or a standard male-female
cable with a gender changer may be installed.
