Packet Repeat Interval S115 L
A parameter that is specific to Slaves and Repeaters is the Packet Repeat
Interval.
The allowable settings are 1 through 255. The default is 1.
This parameter defines a range of random numbers that the Slave will use as
the next slot in which it will attempt to send the packet. For example, if this
register is set to 7, the Slave will choose a number between one and seven as
the next slot in which to transmit. Suppose the random number generator
picks 5, then the Slave will transmit in the fifth time slot. A Slave will
transmit a maximum of once per hopping interval, however, depending on
the duration of the hopping interval and the maximum packet size, more
than one slot per hop is potentially available. The Slave will transmit more
frequently when a Repeat Interval with a smaller range is selected. Choose
1 to have the Slave transmit in the first available slot. Choose higher
intervals for less frequent transmission, or to avoid collisions between many
Slaves in the system.
AT Menu
Link Handshaking S122 P
Link Handshaking is controlled only by the Master unit. If the Master runs
out of free buffers, it will command all Slaves and Repeaters to hold their
data. Once the Master is ready to receive data it will allow the Slaves and
Repeaters to transmit. Possible values are ‘1’ - Enabled and ‘0’ - Disabled.
The default is 1. This register is ignored by all Slave and Repeater units.

Modbus Mode S117 Q
Modbus Mode allows for the CompactRF
TM
to be fully Modbus compatible.
Please contact Microhard Systems for assistance when configuring the unit
for Modbus operation. Optimal Modbus settings rely on several other S
Register parameters.
The allowable settings for this register are:
*0 Disabled
1 Enabled
