SERIAL OUTPUT
The
ACT3X
has can have an optional USB, Ethernet or RS232C compatible serial interface. The USB connection is a Type B
socket, the Ethernet is a standard RJ45 port and the RS232 interface is made via a 9-pin miniature D connector on the rear panel.
See
for connection details. The instrument is not supplied with serial interface cables.
The instrument sends and receives various information out through the serial interface. Under normal operation, the status of the
limits is sent as each event occurs. The user can also request the actual value of the display be sent on a continuous basis. The
user can also request the minimum and maximum values be sent on demand, as well as the current set up of all parameters of the
instrument and program the unit remotely. Software is available to allow programming and to show real time data, or export the
real time data to an Excel
TM
spreadsheet.
The instrument is fully programmable via the serial interface. The user can remotely set the modes, limits, hysteresis, scale
factors and so on, as well as reset either or both the limits.
6.1
Data from the Serial Interface
The messages below are sent from the instrument as each event occurs. Other information is sent on demand and is covered
in the following section.
The messages are sent as standard ASCII and all messages end with a carriage return
<CR>
. There is no Line feed sent.
However, most terminals, printers and computers have the ability to automatically add a Line feed to a carriage return.
SS1
LIMIT 1 has tripped
SS2
LIMIT 2 has tripped
SR1
LIMIT 1 has reset
SR2
LIMIT 2 has reset
SR3
Both Limits have been forced to reset (
RESET
button pressed)
If the user sends a Send display Data (
@D1
) command, the front panel display value is transmitted at the display update rate
(Refer to
). This data is sent as it is displayed on the unit.
@D1
will send data continuously
@D2
will stop data from being sent
@PI
will identify the unit
@C1
will send over the current configuration
6.2
Serial Commands
The instrument responds to a number of commands sent to its serial port. All commands begin with
@
end with a carriage
return
<CR>
. All illegal data is ignored.
There are basically two groups of commands. The first group are
Run Mode
commands and do not affect the operation of
the unit, other than the execution of the command. The second group is
Control
commands that require further information
from the operator.
NOTE:
Control
commands suspend operation of the instrument until completed.
6.2.1
Run Mode Commands
These commands do not interfere with the operation of the instrument. They result in an action only. All commands
are activated after the carriage return
<CR>
or
<Enter>
is pressed. Commands entered are not echoed back to the
user. However, the results, if any, are sent back to the user.
The following are valid
Run Mode
commands. Enter the command and then
<CR>
.
Command Action
Response
@D0
Send current displayed value Unit sends current displayed value once
@D1
Send display data
Unit sends display data until @D2 command
