1. With the power to all units turned off, connect all MultiTasker units to the control unit
by “looping” a control cable (ALTINEX # RC5215MT recommended) from the RS-
232 port of one unit to the next.
2. Turn on the power switch to only one unit, then send the ASCII command
[SETU0] — this will set the powered unit ID to 0, even after the unit power is
turned off.
3. Turn off unit
0 and turn on the next unit.
4. Send the command
[SETU1], thereby setting the second unit ID to 1.
5. Repeat steps 3 and 4 for the number of units you are using, and increment the unit
number for each successive unit. Up to 10 units may be looped this way.
Note: Since MultiTasker enclosures are pre-set from the factory with Unit ID=0, you may
start this process with the second enclosure and use ID=1.
Common Commands Used to Control the MultiTasker
To turn on an output of a distribution amplifier card with output on-off control, or to turn
on one input of a switcher card (which turns off the other inputs), use the
[ON] command
as follows:
[ONmCnUi] to turn on one input or output, where
m = input or output number
n = card slot number
i = unit number
To turn off an output of a distribution amplifier card with output on-off control, or to turn off
the input of a switcher card, use the
[OFF] command as follows:
[OFFmCnUi] to turn off one input or output, or [OFFCnUi] to turn off all inputs
or outputs
A command can be issued to a single card, or to a group of cards. (This is useful when using
several cards to manage a multi-channel signal, for instance when using five cards to manage
RGBHV signals.) Cards can be grouped using the
[WR] command as follows:
[WRCnCoCpCq…GkUi] where
n, o, p, q = card slot numbers
k = group number
Other commands can now refer to the group as they would a single card, by substituting
G for C in the command string. Each enclosure can contain up to a maximum of nine groups.
Example:
[WRC1C2C3G5U1]
After executing this command, card 1, 2, and 3 of unit 1 will be grouped as group 5. To clear
the members of a specified group, issue the command
[CLRG5U1]
