Feedback Control
The next commands are a function of both the card and the front panel and
allow flexibility over when and how card information is displayed.
7. [FBD]
This command turns feedback delay on or off. It is necessary when
installing some newer cards in older systems. If the system does not
receive all of the feedback from the card, the card may be
communicating too fast. This command will slow down the card's
communication rate.
Command Format: [FBDm]
m
= Delay (0= no delay, 1= delay 100mS)
Example:
The command [HELPC4] is sent to the card in slot 4. Some of the Help
file is displayed on the screen, but most is missing. Send the command
[FBD1] to slow down the rate at which the card sends
feedback to the
system.
8. [?]
This command displays general information about a MultiTasker and
its installed cards.
Command Format: [?Ui]
Ui
= Unit ID (i = from 0 to 20)
Example:
A MultiTasker with unit ID 1 has a front panel with part number
MT101-101 and contains an MT103-122, MT103-123, and MT109-
100. Send the command [?U1] and receive the following feedback:
[(MT101-101U1)(MT103-122C01)
(MT103-123C02)(MT109-100C03)]
MT101-101U1
= Panel number/unit ID
MT103-122C01
= MT103-122 is in slot 1
MT103-123C02
= MT103-123 is in slot 2
MT109-100C03
= MT109-100 is in slot 3
9. [?C]
This command displays general information about a card and its status.
Command Format: [?Cn]
Cn
= Card ID (n = # from 1 to max slots)
Example:
The MT109-100 in slot 4 has Input 1 selected. Send the command
[?C4] to receive feedback status similar to the following.
Example:
[(MT109-100C04)(VR690-0179-006C04)
(IN1C04)(VO32C04)(VI3232323232323232C04)(VM0C04)]
All status feedback is enclosed in brackets, "[ ]". Each data field within
the status is enclosed in parentheses. The first two characters identify
the status type. The last three characters are the card’s ID.
MT109-100
= Card model number
VR690-0179-006
= Firmware version
IN1
= Input select (1-8)
VO32
= Volume level (1-32)
VI3232...32
= Input gain settings
VM0
= Mute (0= off, 1= on)
The input gain line is read left to right representing Inputs 1-8 and the
gain level to which each is set. The first two digits show the gain level
for Input 1. The third and forth digits are for Input 2 and so on.
10. [STA1]
This command enables automatic feedback from the front panel. The
command affects any card with auto-feedback capability, not just the
MT109-100. The default at power on or reset is STA0, off. For more
