C
ONFIG
Display a list of the current RPM1 configuration.
This will also set FLOW control to none to enable simple 3 wire serial communication
Valid range
None
DEFAULT
Set all RPM1 configuration settings to their factory default values.
Valid range
None
RESET
Exit the modem and force a software reset.
Any changed parameters will take effect after the modem has restarted.
When exiting the configurator, the HOST device must ensure the SETUP pin is high
otherwise the configurator will be re-entered after the reset.

Two RPM1 modules can communicate with each other provided they have matching
Unit numbers and Site codes.
default
0
Valid range
0 to 15
S
ITE
Sets the Site address
The site number is used to distinguish between groups of operating modems. The site
code is an address extension to the unit number.
default
0
valid range
0 to 7
A
DDR
Updates the unit number value.
This command is used for changing the unit number in RAM without updating the
unit number stored in EEPROM. This enables the RPM1 to support point-to-
multipoint communications.
Upon using this command the configurator is exited and the modem operation is
resumed. The modem is not reset when the configurator is exited.

T
HRUPUT
Sets the on-air data throughput.
Three possible settings are provided.
max: sets the maximum data throughput of the RPM1.
slots: effectively reduces the on-air throughput. This opens up ‘time slots’
allowing other RPM1 pairs, operating within close proximity, equal
opportunity to transmit data.
slotsw: increases the ‘time slots’ even further to allow more RPM1 pairs to
operate.
