Martel Electronics M2000 - Manual (Page 24)

REMOTE IEEE-488 RS-232 Sequential Overlapped
(Remote command) Places the M2000 into the remote state. This command duplicates the
IEEE-488 REN (Remote Enable) message. When the M2000 is in the remote state, and not
locked out, only the LOCAL key is active. If the front panel is locked out, no front panel keys
are active. See the LOCKOUT command. To unlock the front panel, use the LOCAL com-
mand, or cycle the M2000 power switch.
Parameter: (None)
Example: REMOTE
*RST IEEE-488 RS-232 Sequential Overlapped
(Reset Instrument command) Resets the M2000 to the power-up state. *RST holds off execu-
tion of subsequent commands until the reset operation is complete.
A reset action evokes the following commands and values:
Command Value
OUT 0 V
RANGE 0.1 V
STBY (No output)
Response: (None)
Example: *RST
Place the M2000 in a reset condition, evoking the commands and values shown above.
*SRE IEEE-488 RS-232 Sequential Overlapped
(Service Request Enable command) Loads a byte into the Service Request Enable (SRE) reg-
ister. (See "Service Request Enable Register (SRE)". Since bit 6 is not used (decimal value
64), the maximum entry is 255 - 64 = 191.
Parameter: <value> (the decimal equivalent of the SRE byte, 0 to 191)
Example: *SRE 48
Enable bits 4 (MAV), and 5 (ESR).
*SRE? IEEE-488 RS-232 Sequential Overlapped
(Service Request Enable query) Returns the byte in the Service Request Enable (SRE).
Response: <value> (the decimal equivalent of the SRE byte, 0 to 191)
Example: *SRE? returns 48
Returns 48 when bits 4 (MAV), and 5 (ESR) are enabled.
*STB? IEEE-488 RS-232 Sequential Overlapped
(Status Byte Register query) Returns the byte for the Status Byte Register. See "Status Byte
Register (STB)" in Chapter 4.
Response: <value> (the decimal equivalent of the STB byte, 0 to 255)
Example: *STB? returns 96
Returns 96 if bits 5 (ESR) and 6 (MSS) are set.
STBY IEEE-488 RS-232 Sequential Overlapped
(Standby command) Deactivates the M2000 output if it is in operate. This is the same as
pressing the M2000 front panel A key.
Parameter: (None)
Example: STBY
Disconnect the selected output from the M2000 front panel terminals.
