HN-591

Set Data Transmit Delay

When used in conjunction with the minimum data length parameter, this sets the

amount of time from the receipt of a first byte of data from the host until the radio

will transmit in transparent mode. Default is 00H which causes transmission to occur

without any delay. When a host is sending a group of data that needs to be sent

together, setting this parameter will provide time for the group of data to be sent by

the host before the radio transmits. If the length of data to be sent together is longer

than the time slot can send, the data will not be sent together but will be broken up

over multiple hops. The length of time the radio will wait is equal to the specified

value times the hop duration.

Set Slot Assignment Mode (base station only)

Sets whether the base station will assign remote transmit slots dynamically, based on

the number of remotes currently registered or whether the base station will assign

remote transmit slots statically, based on the maximum number of remotes parameter.

If static slot assignment is selected, make sure maximum number of remotes is

correctly set. Otherwise remote transmit performance will suffer as transmit time will

be reserved for remotes that may not exist. The dynamic assignment mode will

generally be preferred; however, the static assignment mode will result in a static

maximum data length parameter.

Set Base Slot Size (base station only)

Sets the amount of time allocated for transmission on each hop for the base station

time slot in 4-byte increments. Maximum value is

2FH which corresponds to 188

bytes. If using a protocol mode, attempting to send a packet with a length longer than

this setting will cause the packet to be discarded.

Set ARQ Mode

Sets ARQ mode when set to 0 which is the default. In this mode the radio will resend

an unsuccessful transmission until either successful or packet attempt limit attempts

have been made. When set to 1 selects redundant transmit mode that will send every

transmission packet attempt limit times regardless of success or failure of any given

attempt. When redundant transmit mode is used, receiving radios will discard all

subsequent retransmissions once the transmission has been successfully received.

Thus the receiving host will receive just one copy of the transmission.
