Lake Shore Model 330 Autotuning Temperature Controller User’s Manual
Remote Operation 4-13
4.3.3 Interface Commands
ADDR Set IEEE Address.
Input: ADDR [address]
[address]: An integer from 1 to 30. Address 0 and 31 are reserved.
Returned: Nothing
Remarks: Sets the IEEE address. The Model 330 is factory preset to 12.
ADDR? IEEE Address Query.
Input: ADDR?
Returned: 1 to 30.
Remarks: Returns the current IEEE address setting. The Model 330 is factory preset to 12.
END Set End Or Identify (EOI) Status.
Input: END 0 or END 1
Returned: Nothing
Remarks: Sets the EOI status: 0 = enabled, 1 = disabled. When enabled, the hardware EOI line
becomes active with the last byte of a transfer. The EOI identifies the last byte allowing for
variable length data transmissions.
END? End Or Identify (EOI) Status Query.
Input: END?
Returned: Current EOI status: 0 = EOI enabled, 1 = EOI disabled.
MODE Set Local, Remote, or Remote With Local Lockout Mode.
Input: MODE 0, MODE 1, or MODE 2
Returned: Nothing
Remarks: Sets the Model 330 mode: 0 = Local Mode, 1 = Remote Mode, 2 = Remote Mode with Local
Lockout. Press the front panel Local key to set the Model 330 to local provided the key has
not been disabled by local lockout. The Model 330 powers up in local mode.
Example: At the end of a command string, MODE 0 maintains constant local operation.
MODE? Mode Query.
Input: MODE?
Returned: Current mode setting: 0 = local mode, 1 = remote mode, 2 = remote mode with local lockout.
TERM Set Terminating Character Type.
Input: TERM 0, TERM 1, TERM 2, or TERM 3
Returned: Nothing
Remarks: Sets the terminating character type from 0 to 3 defined as follows:
0 = Carriage return and line feed (CR)(LF
EOI
)
1 = Line feed and carriage return (LF)(CR
EOI
)
2 = Line feed (LF
EOI
)
3 = No terminating characters – EOI line set with last data byte if enabled (End)
Terminating characters are sent when the Model 330 completes its message transfer on
output. They also identify the end of an input message. This command works only with the
IEEE-488 Interface and does not change the serial terminators.
