3.2.2.3

REMOTE CHANNEL

This function is used to remotely control other power supplies from the front panel of an MBT
power supply included in the remote configuration (see PAR. 1.4.1 and 1.4.2).

3.2.2.3.1 GENERAL NOTES FOR REMOTE CONFIGURATIONS USING IEEE 1118 BUS

1.

The remote configuration must have one (and only one) MBT configured as a controller
(“G” option enabled) on the IEEE 1118 bus.

2.

Each power supply in the configuration must be preset with unique node addresses.

3.

No more than 27 units can be connected to a remote configuration.

4.

The units must remain powered down for approximately 10 seconds before power is
restored to allow the internal memory chips to stabilize.

5.

When applying power to units in a remote configuration, the unit with the “G” option
enabled must be the last unit powered up.

6.

Any MBT front panel (keypad and display) can be used to control any other power supply in
the configuration (regardless of which power supply has the “G” option enabled).

7.

Upon initiating remote operation, it is necessary to send commands for output status,
polarity (MR and MGR Models) and mode, for the display to be updated.

8.

Status LEDs of the controlling power supply reflect the controlling power supply status, not
the controlled power supply.

9.

It is possible for an MG or MGR Model to be remote controlled using its own keypad, thus a
single unit with “G” option enabled could be operated in remote mode using its own key-
pad. As an example, an MG Model could be commanded to enter Current mode by remote
control even though a Current mode command will not be accepted through Local mode
SHIFT then Iadj command.

10. Remote control only affects the controlled power supply after the first command is issued.

Once the first command is issued, the display of the controlled power supply reads
“Remote control” and its Local keypad is disabled.

11. The controlled power supply remains in “Remote control” status even after the control-

ling power supply exits remote control operation. To put the controlled power supply into
Local mode, press SHIFT then CLEAR ENTRY.
