APPENDIX A: MOBILE RADIO IPMESSAGE PARAMETERS
2003 IPMobileNet, Inc. 46 IPSeries MR User Manual / Rev. A / 08-Apr-03
Data Field Description
txdelay=x
Setting Transmission Delay.
Where “x” is number of slots, from 0 to 15, to be delayed. Use this command to delay
back-to-back radio transmissions to reduce the chances of colliding with the base station
downlink transmission. Before typing in the command, the radio must be unlocked. The
command is effective immediately. When setting the delay to a non-zero value, the
“rxinprogressmessage” in the base must be set to 1.
Default Value = 2
mtu=n
Setting MTU.
Where “n” is the desired MTU in decimal value, 1500 maximum. Use this command to
change the MTU. Before typing in the command, the radio must be unlocked. The
command is effective immediately.
When the radio receives a packet with size greater
than the MTU, it will return an ICMP packet (type=3, code=4) to the source. The original
received packet will be discarded.
Default Value = 1500
internalgpsinput=1 (input protocol =
TSIP)
internalgpsoutput=1 (output protocol
= TSIP)
internalgpsinput=2 (input protocol =
TAIP)
internalgpsoutput=2 (output protocol
= TAIP)
internalgpsoutput=3 (output protocol
= NMEA)
Setting Internal GPS Input/Output Default Protocol.
Use this command to configure the default protocol for the internal GPS. Before typing in
the command, the radio must be unlocked. Once the command has been entered, the
radio should be reset with the “reboot” command.
Default Value = internalgpsinput=2, internalgpsoutput=2
tftpoptions=s,t
Setting TFTP Packet Size and Delay between Packets.
Where “s” is the packet size in number of bytes (e.g. 512), and “t” is the delay between
packet transfers in seconds (e.g. 3).
Use this command to change the default over-the-air TFTP protocol options (256 bytes for
packet size and 3 seconds for packet delays). These options do not apply to TFTP packets
that are not sent over-the-air, which are fixed at 512 bytes and no delay. Before typing in
the command, the radio must be unlocked. The command is effective on the next file
transfer.
Default Value = 256, 3
diversityprocessor=0
Disable Diversity Processor.
Use this command to disable the diversity processor. The mobile Firmware automatically
detects whether the diversity processor is present and enables it if it is detected. When the
diversity processor is enabled, the diversity processor will handle diversity. If the diversity
processor is present but is disabled with the command by the user, the main processor will
handle diversity. Before typing in the command, the radio must be unlocked. The
command is effective immediately. To re-enable the diversity processor, the user must
reboot the radio using the ‘reboot’ command.
Default Value = 1 if found, 0 if not found (auto-detect)
