RS232 Entries and Printouts
7.1.5 ON-OFF (Control Toggle) Commands: The RS232 commands that simulate the toggle
action of the keys on the lower-left of the front panel are shown in Figure 7-7. The
"+", "–", and "#" characters following the command letters represent ON status, OFF
status, and (for PCM monitor) reversed inputs. Refer to Section 1 for further
description of the key functions.
7.1.6 CALL INITIATE (Signaling) Commands: The RS232 commands that simulate the actions
of the keys in the upper right side of the front panel are shown in Figure 7-8. The "+",
and "–" keys are used to indicate the key states.
7.1.7 EVENTS DISPLAY Commands: The RS232 commands that simulate the actions possible
after the EVENTS DISPLAY function on the front panel has been activated, are shown in
Figure 7-9. The commands permit the selection of a given event for detail printout,
provide simulation of the
and CANCEL keys.
7.1.8 METER DISPLAY Commands: The RS232 commands that simulate the key actions after
the METER DISPLAY function has been selected are shown in Figure 7-10. The MENU
and MEASURE selections possible are dependent on the CIRCUIT CONFIGURE
selections.
COMMAND
(Lxxx...x)
Log On with password xxx...x: A password is required if the setting of the
CONFIG'N PASSWORD menu is YES. If NO, a password is not required, and the
AM8a acts on RS232 commands as soon as a "?" or "(" character is received. Setting
of the password is described at the end of this table. (The user may "white it out" of
this manual, if desired.)
Log Off ("Bye"): This command should be entered as soon as the operator is
(B)
finished with entering RS232 commands. In any case, there is an automatic Log off if
there is no activity at the RS232 port for a period of two minutes. This is only required
with passwords.
(EC+)
Echo On: This is the default status for the RS232 entries. When echo is on, every
character received by the AM8a (on the RX line) results in the AM8a returning the
command on its TX line. A terminal set in full-duplex mode will print the character,
thereby acknowledging that the AM8a has received it. If commands are output from a
computer, the computer program should be written to wait for the echoed character
and check it.
