7.2 MT101-114/115/117 OPERATION
This section describes the programming and
control functions for the MT101-114, MT101-115,
and MT101-117. The MT101-114 has the same
programming capabilities as the MT101-115/117
with the exception of the key and LED functions.
On the MT101-115/117, the front panel uses 36
programmable keys to control plug-in cards. Each
of the 36 keys has five states. A total of 180
subroutines are available to perform different
functions based upon each key's state.
IDENTIFY UNIT ID
The [IDUi] and [IDU] commands can be used to
locate a specific unit on the RS-232 bus. See the
[IDUi] and [IDU] commands for details.
POWER-UP SUB1 (U0/U1)
SUB1 is always executed at power-up or on the
reset command, [RES]. Typically, SUB1 is used to
place the system cards to default settings. See the
{WRS} command for programming details.
KEY PROGRAMMING
Each key may be programmed to execute one
subroutine for each of the five key states. See the
{WRK} command for details.
State 1 Key is pressed and LED is OFF.
State 2 Key is pressed and LED is ON.
State 3 Key is pressed and LED is FLASHING
State 4 Key is Pressed and Held for 2.5 sec.
State 5
Key is Pressed and Held for 2.5 sec
during power-up.
MATRIX KEY CONVENTIONS
The front panel is designed to use the center
group of keys for Matrix card input and output
selections.
Input Selection = Keys 13-28
Output Selection = Keys 29-36
Card Selection = Keys 7-12
Using these conventions, the LEDs will flash
automatically showing each connection after a
completed input-to-output command has been
issued. The user should NOT issue LED
commands to these LEDs during these
sequences.
MEMORY
The memory is used to save key and subroutine
programs. It is non-volatile and has a storage
capacity of 64KB. The only size restriction of an
individual subroutine is that of overall available
memory.
SAVING CARD CONFIGURATIONS
Commands used for MultiTasker cards such as
[ON], [OFF], and [IO] that end in "S" will be
saved to the memory of each card. Commands
not ending in "S" will be executed but not
restored when the system is reset or powered
off, and then on again.
SUBROUTINES AND FUNCTION TYPES
The subroutine for a key may be programmed to
execute a complete function "I1O2C3" or a
portion of a function. As an example, matrix
functions will use one key to select the input
number, "I1", another key to select the output
number, “O2", and a final key for the group/card
ID, “C3”. See the {WRS} command for further
details.
Complete and incomplete functions mean two
different types of subroutines. Subroutines with
complete functions contain one or more
stand-alone functions which are all executed
with a single key press. Subroutines with matrix
functions require two or more keys to be
pressed to complete a single executable
function.
