Instrument Identification; Front Panel; Auto Default - Ametek 7280 Instruction Manual

Bit 5 New ADC values available after external trigger
Bit 6 Asserted SRQ
Bit 7 Data available
NOTE: this command is not normally used in GPIB communications, where the
status byte is accessed by performing a serial poll.
N Report overload byte
Causes the lock-in amplifier to respond with the overload byte, an integer between 0
and 255, which is the decimal equivalent of a binary number with the following bit-
significance:
Bit 0 not used
Bit 1 CH1 output overload (> ±300 %FS)
Bit 2 CH2 output overload (> ±300 %FS)
Bit 3 Y channel output overload (> ±300 %FS)
Bit 4 X channel output overload (> ±300 %FS)
Bit 5 not used
Bit 6 input overload
Bit 7 reference unlock
MSK [n] Set/read service request mask byte
The value of n sets the SRQ mask byte in the range 0 to 255
REMOTE [n] Remote only (front panel lock-out) control
Allowed values of n are 0 and 1. When n is equal to 1, the lock-in amplifier enters
remote only mode in which the front panel control functions are inoperative and the
instrument can only be controlled with the RS232 or the GPIB interfaces. When n is
equal to 0, the front panel controls function normally.

6.4.11 Instrument Identification

ID Identification
Causes the lock-in amplifier to respond with the number 7280.
VER Report firmware version
Causes the lock-in amplifier to respond with the firmware version number. The
firmware version number is the number displayed on the Configuration menu.

LTS [n] Display on/off control
The value of n controls the front panel electroluminescent display according to the
following table:
n Selection
0 Display off
1 Normal operation
