Campbell Scientific TX320 Transmitter - Manual (Page 64)

Appendix F. Extended ASCII Command Set
Unless otherwise noted, the transmitter will respond to all commands with one
of the following:
“OK[CR][LF]>" if command was accepted,
"Bad parameter[CR][LF]>" if a command parameter was invalid,
"Unknown Format[CR][LF]>" if there are too many or too few
parameters,
"Access Denied![CR][LF]>" if the command requires a higher access
level,
"Unknown Command[CR][LF]>" if the command is unknown,
"Execution Error[CR][LF]>" if the command fails during execution,
"Transmitter Must Be Disabled[CR][LF]>" if the transmitter must be
disabled prior to using this command.,
"Transmitter Must Be Enabled[CR][LF]>" if command must first be
enabled,
"Configuration Not Recognized[CR][LF]>" if configuration is invalid,
If the command was a request for a configuration parameter the transmitter will
respond with:
<cmd>=<data>[CR][LF]> When returning data parameters.
F.1.1.3 Command Access Level
All commands are subject to an access right to restrict access to calibration and
test commands. Two access levels are defined: USER and TECHNICIAN. An
error will be returned if a TECHNICIAN level command is entered while at the
USER command access level. USER level commands are always available
including when at the TECHNICIAN command access level. The
TECHNICIAN level commands are not described here.
The command access level is changed by using the password protected
TECHMODE command. After power up the access level is always USER. The
access level of each command is noted in each command description.
Some commands are only available when transmissions are disabled. This is
also noted along with each command description.
F.2 General Configuration Commands
F.2.1 Clock Read/Set
Syntax:
TIME= yyyy/mm/dd hh:mm:ss
Access level: USER
TX320 State: Enabled/Disabled
This command sets the date and time in the transmitter. The date and time will
be overwritten when a GPS time synchronization occurs. Self-timed
transmissions will not occur until the time has been set either using this
command or from the GPS. Random transmissions will occur with or without
time being set.
The real time clock starts at 01/01/2000 00:00:00 at power up.
