internal power supply is designed to operate from all nominal power sources from 85 to 265 volts a.c. at 50/60Hz without requiring the user to change any settings. In case of failure, do not attempt to change the internal fuse because it will never blow unless the power supply fails catastrophically. The power supply will need to be serviced by a competent service technician in such a case.

3.7MORE ABOUT USING THE 1788A-R

3.7.1 Assigning A Bank

All 1788A-R’s must be assigned to a NET Number bank. This is done by a rotary switch on the Power Unit (see Fig. 3-5). Banks from 1 to 8 can be selected. Multiple units should never be assigned the same Bank number.

3.7.2 Setting Up The MIDI Channel

If you intend to use a MIDI controller with 1788A-R’s, then you need to set up their MIDI Channels. This is done by use of a secondary function of the Tone Buttons.

1.Press both Tone buttons and Channel 5 and release. The Adjust dial will be transferred to the MIDI channel.

2.Spin the Adjust dial until the desired channel number is seen in the display window.

3.When done, press one of the Tone buttons to escape.

You can check the channel number by the above procedure without turning the Adjust dial.

NOTE: See Section 2.2.6 relating remote control strategies to the setting of the MIDI Channel numbers.

3.7.3 Initial Sync

When 1788A’s and 1788A-R’s are powered up while connected to a network, or plugged into a network when they do not have an IP address yet assigned, they will communicate with the DHCP Router and receive unique IP addresses automatically. Only when a unit has a unique IP address can it become active on the network. This will take place quite rapidly. The 1788A-R will automatically begin receiving meter data from preamplifiers and will sort out their IP addresses and Net numbers. All units with NET numbers that fall within the 1788A-R’s Bank are assigned to the Unit Select buttons that coordinate with each Net number.
