ZONE DATA

Read Zone Statistics Log

The transceiver divides its frequency operating spectrum into eight

3.0 MHz-wide zones or sub-bands. (These are the same zones referenced by

the

SKIP command described earlier.) Data frame statistics are maintained for

each zone to indicate the transmission quality of data through the network.

This information is useful for identifying zones where significant interference

exists.

Historical information on the quality of each zone can be accessed using the

ZONE DATA command. The report shows you the number of data frames sent,

the number received, and the number received with errors. If an excessive

number of errors are seen in one or more frequency zones, it may indicate

interference, and you should consider “skipping” those zones using the

SKIP

command (See “SKIP [NONE, 1...8]” on Page 53).

Note: If a frequency zone has been skipped, all counts for that zone will be

zeros.

The

ZONE DATA format is displayed as follows:

1:TX TOTAL 00000000

1:RX TOTAL 00000000

1:RX ERROR 00000000

8:TX TOTAL 00000000

8:RX TOTAL 00000000

8:RX ERROR 00000000

All data is based on payload packets. Incoming network data may be divided

into multiple packets for over-the-air transfers. The number before the colon

represents the zone.

TX TOTAL is the transmit packet total. RX TOTAL is the

receive packet total.

RX ERROR is the total number of received packets with

CRC errors. All zone data is reset with the ZONE CLEAR command.

9.0 TROUBLESHOOTING

Successful troubleshooting of a TransNET system is not difficult, but

requires a logical approach. It is best to begin troubleshooting at the Master

station, as the rest of the system depends on the Master for polling instruc-

tions and synchronization data. If the Master station has problems, the oper-

ation of the entire network will be affected.

When communication problems are found, it is good practice to begin by

checking the basics. All radios in the network must meet these basic require-

ments:

• Adequate and stable primary power

• An efficient and properly aligned antenna system

• Secure connections (RF, data & power)
