MEM
Purpose Read the memory test status.
Syntax “MEM”
Remarks
On power up, a memory test is run to check the integrity of the MFC-CB internal
data NVRAM. If the memory has been corrupted, "FATAL MEMORY
FAULT" is displayed on power up to alert the user, and the memory test status
command returns a ‘0’. The command returns a ‘1’ if the memory is OK.
Example Command:
Reply:
“MEM”
“0”

MFCCH(n)(=)
Purpose Read or set the active device channel and mode (voltage or current).
Syntax “MFCCHn”
“MFCCHn=channel, mode”
Arguments
n:
channel:
mode:
Device channel number (optional). Uses the active device
channel if not given.
'1' to address DEV1 settings.
'2' to address DEV2 settings.
The optional MFC Switchbox channel.
0 Disables the MFC Switchbox.
1 to 5 Enables the MFC Switchbox selects the MFC
channel to use for optional MFC Switchbox.
The electrical mode.
‘v’ Voltage control and measure mode. The selected channel
will be used for voltage setting and measuring
‘mA’ Current loop control and measure mode. The selected
channel will be used for current loop setting and measuring.
‘ ‘ If this argument is not given, the MFC-CB will use the
selected channel to measure the voltage, and will always
use channel 1 to set the voltage. This is used to measure
voltage MFM’s that are connected to channels
2 through 5 with an MFC controlling on channel 1.
Defaults “MFCCHn=1,V”
Remarks
The MFC-CB supports voltage or current controlled MFC’s. There is also an
available MFC Switchbox, which is assigned to either "DEV1" or "DEV2",
depending on the last MFCCHn sent.
Example Command:
Reply:
“MFCCH1=2,V”
“2, V”
