System Status • LCD Display

The top line of the LCD display shows the system is a DMX “6-PORT”

MERGER, unless the system conguration menu items are being accessed.

The bottom line of the LCD display shows the number of valid DMX inputs

being received and merged (“MERGE 0” thru “MERGE 6”), unless the system

conguration menu items are being accessed, or abnormal system status is

detected and displayed as follows:

RTC ERR!

Displayed when the system detects a runtime counter (RTC) error. This

occurs when there is an invalid hard-key code, and the runtime counter

is greater than 2160 hours (90 days). Refer to menu item “HARD-KEY”

on page 17 for further details.

USB ERR!

Displayed when the Tech Port is enabled and connected to a PC with

the terminal emulator running, and then a USB error occurs. When using

the Tech Port to monitor DMX via a PC, be sure to read and follow the

instructions included in the USB Tech Port Operation section starting

on page 19 of this manual.

LOCKED!

items and the programming switches are locked out. To toggle between

“LOCKED!” and “UNLOCKED” press and hold down the “EXECUTE” and

then “ESCAPE” switches at the same time for 4-5 seconds.
