All J-PACK Series relay packs are equipped with a user interface located
on the front panel of the chassis. The user interface provides access to all
programming and conguration settings. System status is easily visible on
the LCD display and LED indicators.
All of the programming is accomplished using four (4) switches. Within a few
minutes, most users will nd the menu structure very intuitive and easy to
navigate. All conguration settings are automatically stored into an on-board
EEPROM.
LCD Display
The LCD display is capable of displaying 2 lines of 8 characters. A backlight
automatically comes on when activity is sensed. The LCD contrast can be
easily adjusted for optimum viewing. Refer to menu item “LCD VIEW” on
page 27 for further details.
Programming Switches
The MENU UP/DOWN ( ) switches are used for navigating through the
various system conguration menu items. They also allow for programming
of other specic parameters within a selected menu. Pressing and holding
either switch will speed up the scroll rate, which can be helpful to speed up
the conguration time.
The EXECUTE ( ) switch is normally used to select/enter a menu item,
advance forward within a selected menu item, or toggle between parameters
within a selected menu item.
The ESCAPE ( ) switch is normally used to back up within a selected
menu item one step at a time or exit the menu completely.
The RESET switch has two purposes. First, it allows for quick exit from a
menu item after a programming change and automatically puts the system
into normal run mode. Second, it provides a soft reboot for the systems
microcontroller.
The programming switches are backlit with blue LED’s. The LED’s
automatically turn on when activity is sensed. The LED intensity can be
adjusted in the “LED INT” menu. Refer to page 27 for further details.
NOTE: When the J-PACK Series relay pack is powered up, the menus are
“LOCKED!!” with access only to the basic system conguration
menus, which includes setting the DMX start address as well
as enabling or disabling the end-of-line DMX termination. The
menus need to be “UNLOCKED” to access the advanced
system conguration menus. To toggle between “LOCKED!!”
and “UNLOCKED” press and hold down the EXECUTE and then
ESCAPE switches at the same time for 4-5 seconds.
A detailed procedure for programming all system conguration
menu items can be found on page 23 to 27.

System Status • LED Indicators
RUN (Green)
Illuminates when the power is on and the microcontroller status is in normal run mode. The LED
ashes once every 2 seconds when the system is in STANDBY mode.
RxD (Yellow)
Illuminates when valid DMX is received. Flashes when invalid DMX is received.
ERROR (Red)
Illuminates whenever an error is sensed. The error type is displayed on the LCD.
6 x RELAY OUTPUT STATUS (Blue)
Illuminates when the corresponding relay (1 thru 6) is in the “on” state. The LED intensity can be
adjusted in the “RLY INT” menu. Refer to page 27 for further details.
NOTE: When operating in 208/240V mode, the relays are paired (1&2, 3&4, 5&6) and there
are 3 output circuits. Relay output status indicators 1 and 2 represent output circuit 1.
Relay output status indicators 3 and 4 represent output circuit 2. Relay output status
indicators 5 and 6 represent output circuit 3.

System Status • LCD Display
When DMX is being received, the top line of the LCD display shows the DMX start address
(“DMX:001” to “DMX:512”), unless the system is in DMX patch mode, then “DMX:PAT” is
displayed. When DMX is not being received, the top line of the LCD display shows “DRD-6”,
unless the system is in standby mode, then “STANDBY!” is displayed. The bottom line of the LCD
display shows the current status of the system unless the system conguration menu items are
being accessed. Below are descriptions for each status indication.
NO RX!
Displayed when DMX is not being received and the system is not in scene mode.
XXX
Displayed when valid DMX is being received and is not terminated. “XXX” represents the number
of channels being received in each packet of data. For example, if the system is receiving 512
channels will show “512”.
XXX TERM
Same as above, except “TERM” is shown to indicate if the DMX input is terminated. For example,
if the system is receiving 48 channels of DMX control and is terminated, the display will show
“048 TERM”. Refer to menu items “DMX TERM” on page 20 for further details.
SH XX:YY
Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time
is counting down. “XX” represents minutes while “YY” represents seconds. Refer to menu item
“SH TIME” on page 22 for further details.
INF HOLD
Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time
is set for innite (INF) hold. Refer to menu item “SH TIME” on page 22 for further details.
DMX ERR!
Displayed when the system detects a DMX error due to reversed data lines.
OVERTEMP
Displayed when the microcontroller senses an internal over-temperature condition of 185°F
(85°C) or more. All relay outputs are pulsed off until the temperature cools down to 178°F (81°C)
or less. Refer to menu item “CTL TEMP” on page 26 to view the microcontroller temperature.
LOCKED!!
When the J-PACK Series relay pack is powered up, the menus are “LOCKED!!” with access only
to the basic system conguration menus, which includes setting the DMX start address as well
as enabling or disabling the end-of-line DMX termination. The menus need to be “UNLOCKED”
to access the advanced system conguration menus. To toggle between “LOCKED!!” and
“UNLOCKED” press and hold down the EXECUTE and then ESCAPE switches at the same time
for 4-5 seconds.
