baud DTE baud rate
This command sets the host interface (DTE) baud rate. The changed baud rate
will take effect after leaving the configurator using the exit command.
Using a DTE baud rate, with no flow control, greater than the radio through-put,
you should be aware of the 96 byte serial internal receive buffer of the radio
modem. If the internal serial receive buffer overflows then data will be lost. If
hardware flow control is used, no data will be lost.
Command format
baud [n]
where: n =
600, 1200, 2400, 4800, 9600, 14400
19200, 38400, 57600, 115200
airspd On-air data rate
This command sets the on-air data throughput between two Radio Modems. By
reducing the on-air throughput, the air-time usage between a pair of Radio
Modems is also reduced.
To improve data throughput within a network of multiple Radio Modem pairs all
operating within radio range of each other, it is recommended to drop the on-air
throughput. This will effectively reduce the rate of data collisions and packet
retries, thus improving the overall network interoperability.

airspd [n]
where: n =
600, 1200, 2400 – Applies to RMX232-151/173
600, 1200, 2400, 4800, 9600
unit Radio Modem unit address
This command sets the device unit address. To permit two radio modems to
communicate they must have the same unit address and site code.
Multiple modem pairs can operate within close proximity by ensuring each pair
within the group have a unique unit address.
To improve interoperability of multiple radio modem pairs in close proximity, all
units support a listen before transmit (LBT) collision detection. Before a radio
modem attempts to transmit a data packet, it listens for transmission from other
radio modems. Only when no other device pairs are transmitting will the radio
modem transmit its data.
It is recommended that this command is not used to continually change the unit
address in a point-to-multipoint system, as this EEPROM memory location has
a life of only 100,000 write cycles. The command addr is provided for the
purpose of continually changing the unit address, site code and hop count.
