TX320 Transmitter
CSI floating point binary data requires 3 B per data point. Data must be low
resolution. Sign and decimal location are maintained. This is an efficient data
format.
Floating point ASCII requires 7 B per data point. Data must be low resolution.
Sign and decimal location are maintained. Data does not need to be converted
after transmission. Data points are separated by a comma. This is not an
efficient data format, but it is convenient.
Binary, 18-bit, integer data format requires 3 B per data point. All data stored
in the datalogger must be in high resolution. All information right of the
decimal place is truncated. Data is transmitted as a signed, two’s compliment,
18-bit integer. Precision can be maintained by pre and post processing. This is
an efficient data format that requires conversion and post processing. See
Appendix D for details.
7.6.4.3 P126 Result Codes
The result codes can be used to increase the success rate of data transmissions.
When the result code is 0, all went well. When the result code is 2 through 6,
P126 did not execute properly, but can still send the data. A result code of 7
indicates P126 did not execute properly and the data probably cannot be sent
again. Refer to Section 8.2, Result Codes, for more information.
7.6.5 Read Status and Diagnostic Information from the TX320
Edlog Instruction 127 (P127) is used to read status and diagnostic information
from the TX320.
1: TX320 Status (P127)
1: 0000 Status Command
2: 0000 Result Code Loc [ _____ ]
Parameter 1: Status Command
0 Read Time, Uses four Input Locations

2 Read Last Message Status, Uses 14 Input Locations
3 Transmit Random Message, must be followed by command 6. One
Input Location
4 Read Error Register, Uses Ten Input Locations
5 Reset Error Register, One Input Location
6 Return transmitter to online mode, used after command 3, One Input
Location
Edlog Instruction 127 (P127) has four basic functions:
1) Datalogger will retrieve information from the TX320 transmitter.
2) Datalogger will initiate a test transmission on a random channel.
3) Datalogger will reset the error register of the TX320.
4) Return TX320 to online mode following a forced random transmission.
