INSTALLING YOUR MT100-101 6
Step 1. Connect the power entry connector of the
MT100-101 to the power outlet with the
provided power cord. The power supply is
universal and will work throughout the
world with voltages from 110V to 240VAC.
Step 2. If a control system is used to control the
cards in the MT100-101 Multi-Tasker™,
connect the 9-pin D connector of the
MT100-101 to the control system’s RS-
232 port as shown below in Table 4.

Table 4. MT100-101 RS-232 control
Note: Make sure that the transmit pin of the control
unit is connected to the receive pin of the MT100-
101. Also, make sure that the receive pin of the
control unit is connected to the transmit pin of the
MT100-101. See figure 1 and 2.
Step 3. Turn on the power switch of the MT100-
101 Multi-Tasker™.
OPERATION 7
The MT100-101 has many advanced remote
control capabilities, which are accessible through
standard RS-232 communication. The actual
controlling can be accomplished through a
computer, a control system, or any other device
capable of sending RS-232 commands. The factory
settings for the RS-232 port are 9600 baud, 8 bits,
1 stop, and No parity.
Commands used for MultiTasker cards such as
[ON], [OFF], and [IO] that end in "S" will be saved
to memory. Commands not ending in "S" will still be
executed but will not be restored when the system
is reset (power off & power on again).
In this section, "Basic Enclosure" or "Unit" has the
same meaning. The basic enclosure is a complete
and independent card cage that has a controller
and 8 slots for plug-in cards. Each unit or basic
enclosure has its own unit ID that is based on a
number from 0 to 9. Each plug-in card also has its
own card ID that is a number from 1 to 8.
7.1 RS232 CONNECTION
If a control system is used to control the cards in the
MT100-101 Multi-Tasker™ Basic Enclosure,
connect the 9-pin D connector of the MT100-101 to
the control system's RS-232 port. To connect the
Multi-Tasker™ (MT) to a computer or a terminal,
you must have the proper interface cable.
The interface cable must also have the appropriate
connector on each end and the internal wiring must
be correct. Connectors typically have 9 pins (DB-9
connector) or 25 pins (DB-25 connector) with a
"male" or "female" pin configuration.

7.2 RS-232 PROTOCOL
The RS-232 protocol for the MT100-101 uses a
simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
3. One command may carry up to 40
characters including brackets.
