3. This sequence states the command: Set or change the maximum number of Packets Per Interval for
this ISM Subsystem to 4.
4. The console confirms your change: OK
9.2.9 Changing RF Transmit Delay
An ISM Master Radio can be configured to wait a specified number of milliseconds before transmitting a
packet. However, this is not recommended.
The default setting of zero (0) milliseconds is the preferred and recommended setting for this parameter.
Other settings, because they limit data throughput, may degrade system performance.
NOTE
This is a Master Radio function only. Slave devices may accept an entry in this configuration
field, but will ignore any setting you make
Example:
1. Type at*rftto delay at the maintenance port or remotely, where delay is the number of milliseconds a
Master device will wait before transmitting data packets. Example: at*rftto 10
2. Press the Enter key.
3. This sequence states the command: Set or change the number of milliseconds this device will wait
before sending a packet to 10.
4. The console confirms your change: OK
9.2.10 Changing Mode of Operation
When it comes out of the carton, the ISM Radio is neither Master nor Slave. Its hardware supports both.
How it performs depends on choices you make during configuration and setup.
Even after an ISM device has been configured for Master or Slave operation, its Mode of Operation can
be changed remotely through a Routing Table update or at a terminal connected to the maintenance port.
A single-digit code determines whether the device operates as Master or Slave:
Code Number Mode of Operation
3 Radio operates as Master
5 Radio operates as Slave
Example:
1. Type at*type mode at the maintenance port or remotely, where mode is the code number indicating
Master or Slave mode. Example: at*type 3
2. Press the Enter key.
3. This sequence states the command: Set or change this radio to operate as a Master device.
4. The console confirms your change: OK
