Microhard Systems P900 - Hop Interval; Data Format

© Microhard Systems Inc. Confidential 87
6.0 Register/Command Reference
S109 (PP/PMP) Hop Interval
This register is effective only on the Master and is responsible for establishing the rate at which all modems within a
particular network change frequency (hop - from frequency to frequency).
Long hop intervals typically result in the greatest data throughput, however shorter hop intervals may decrease
latency and make the system more immune to interference.
The default setting of 20ms is satisfactory for most applications
Hop Interval S109 should
only be changed if
recommended by
Microhard Support and/or
for specific applications!

This register determines the format of the data on the serial port. The default is
8 data bits, No parity, and 1 Stop bit. The value must match the PC or Serial
Based device that is connected to the data port.
When forcing a module to Command Mode the data port will temporarily
communicate at the default value. When the P900 is retuned to Data Mode, the
serial port settings are returned to those specified in S102 and S110.
