AM8a Instruction Manual
7. RS232 ENTRIES AND PRINTOUTS
This section describes the RS232 commands that are equivalent to functions actuated by keys
on the AM8a front panel. Also described are the printouts of SETUP menus,
EVENTS/DETAILS, METER displays, LED displays, and AUTO PRINT reports. Finally, this
section describes the RS232 connections for a terminal and for chained operation of more than
one unit.
7.1 RS232 COMMAND DESCRIPTION
Functions activated by front panel keys (described in the previous sections) may also be
executed by a terminal or computer connected to the RS232 port on the rear panel. The
following rules apply to RS232 Commands:
•
An RS232 command is initiated by a "(" and executed when a ")" is received. The
")" may also be used alone to repeat the last command sent. Only the characters between
the "(" and the ")" are recognized as a command. (Other control characters, such as
carriage return <CR> and line feed <LF> are not required and will be ignored.)
•
An "=" sign precedes a value change in SETUP commands.
•
A help menu may be displayed by typing "?". As directed in the menu, "1" through
"6" can then be typed to get additional information.
•
The AM8a echoes all characters received after it has processed them. The echo may
be disabled if required, but leaving echo enabled is recommended while computer down-
loading, for output control and error checking purposes.
•
A computer's down-load program should be setup to wait for the echo of the
previously sent character prior to sending the next character. This ensures the AM8a has
had adequate time to process the command and prevent a buffer overflow. This also
prevents loss of data which may cause down-load failure.
•
The first letter of many commands corresponds to pressing a key on the front panel for
that function (e.g. "C for CONFIG'N, "E" for EMULATE, "A" for ANALYZE). Other
commands may abbreviate a key and its action e.g: "SZ+" for SEIZE ON).
