3 TRANSMITTING FUNCTIONS
3.1 Introduction to Output Data Formats
Chapter 3 TRANSMITTING FUNCTIONS
This chapter describes the different output formats.
3.1 Introduction to Output Data Formats
The type of data to be sent from the VR200 recorder is specified by the TS command
(TS0, TS1, or TS2: see Section 2.3.7), and the output data format is specified by the
FM command (see Section 2.3.8).
Note
The specification of the data type by the TS command is effective only when the ESC T command is sent afterwards. Hence,
changing the specification of the data type by the TS command after the ESC T command is sent will not take effect until the ESC
T command is sent again.
3.1.1 TS0
After sending the TS0 and the ESC T command, you must specify the output format
using the FM command. Data cannot be output if the FM command is omitted.
However, after the FM command has been sent and the data has been read, the data
within the same sample can be read again by specifying the output format once more
using the FM command.
If the next FM command is sent before the specified data have been output completely,
the newly requested data will be output.
Sequence (see also Sections 2.3.7 and 2.3.8)
TS0
ESC T
FMx, xx, xx
(Read all data specified, until the end.)
FMx, xx, xx
(Read all data specified, until the end.)
Note
• Do not send the LF command until the reply data have been read completely after sending the FM command.
• After sending the ESC T command, data will be stored in a buffer and the system will wait for FM or LF commands (regardless
of whether the ESC T command is sent without executing an FM or LF command after the last invocation of the ESC T
command, or whether data have not yet been sent completely.)
• The ASCII code for “ESC” is 1B in hexadecimal notation.
3.1.2 TS1 and TS2
After sending the TS1 (or TS2) and the ESC T command, to read the data you must
specify the output channel using the LF command. It is possible after reading the data
completely to read data for other channels by sending another LF command.
Sequence (see also Sections 2.3.7 and 2.3.9)
TS1
ESC T
LFxx, xx
(Read all data specified, until the end.)
LFxx, xx
(Read all data specified, until the end.)
Note
• Do not send the LF command until the reply data have been read completely after sending the FM command.
• After sending the ESC T command, data will be stored in the buffer and the system will wait for FM or LF commands (regard-
less of whether the ESC T command is sent without executing an FM or LF command after the last invocation of the ESC T
command, or whether data have not yet been sent completely.)
