The TEOM 1405 Monitor supports AK Protocol. This protocol permits a
locally or remotely located computer to obtain information electronically
from the unit. These protocols are described in this appendix.
The AK Protocol allows the user to query the present value of any system
variable remotely, and allows the user to change those system variable
values. The user also can download information from the internal data
logger. The RPComm software program uses this protocol for two-way
communication directly to a personal computer or through a modem.
The following AK Protocol commands are presented in detail on the
following pages:
•
AREG (Ask Register Command).
The user can query the TEOM
1405 Monitor for the current value of any system variable.
•
EREG (Enter Register Command).
The user can assign a new value
to any system variable. Great care must be taken when using this
command, as the value of variables should only be changed when the
monitor is in the appropriate operating mode.
•
SFxx (Set Function xx Command).
The user can send commands
using the <RUN> key and the <DATA STOP> key to the instrument.
Each command is designated by a two-digit code, xx.
•
ASTO (Ask Storage Command).
The user can download a specified
number of records from the internal data logger from the current
position of the data storage pointer. The location of this storage pointer
may be defined by the SSTO command. The values on each line of
output are delimited by commas.
•
SSTO (Set Storage Command).
The user can change the location of
the data storage pointer in the internal data logger, and is used in
conjunction with the ASTO command described above. The data
storage pointer is always located immediately after the last record
transmitted through the RS232 port via the AK Protocol. If the circular
buffer overwrites this location or if the ASTO or SSTO commands
have not been used, the data storage pointer is positioned at the oldest
record in the internal data logger.
