Terminal Block Connection Details NOTE: This option is intended for permanent installation application only. Remove the top panel (lid) of the relay pack chassis to access the contractor termination area, where the required relay output (load) terminals are located. To remove the top panel (lid), remove the ten (10) SEMS #8-32 x 3/8"...
Control Input J-PACK Series relay packs are equipped with DMX input and thru, as well as two (2) auxiliary dry-contact inputs. XLR connectors are provided on the front panel of the relay pack chassis, and breakaway type connectors are provided internally for permanent installation applications.
DRD-6 Controller The DRD-6 is the central electronic control system (aka brain) for all J-PACK Series relay packs. WWW.JOHNSONSYSTEMS.COM DRD-6 RELA Y DRIVER REV.1 1216 SERIAL NUMBER MADE IN CANADA DRD Relay PDB All J-PACK Series relay packs contain a DRD Relay PCB, consisting of 6 relays with terminal block connections for line input and load output for each relay.
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 configuration menus, which includes setting the DMX start address as well as enabling or disabling the end-of-line DMX termination.
System Status • LED Indicators RUN (Green) Illuminates when the power is on and the microcontroller status is in normal run mode. The LED flashes 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.
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 configuration menus, which includes setting the DMX start address as well as enabling or disabling the end-of-line DMX termination.
Quick Programming Reference to System Configuration Menu Items Basic Menus ADDRESS Set the DMX start address. DMX TERM Enable or disable the DMX termination. Advanced Menus RLY TEST Test the relay outputs one at a time, or all at once. DMX O/P Configure the on-board DMX protocol manager for offset or patch mode.
Detailed Programming of System Configuration Menu Items NOTE: When the J-PACK Series relay pack is powered up, the menus are “LOCKED!!” with access only to the basic system configuration 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”...

Advanced Menus RLY TEST Test the relay outputs one at a time, or all at once. A technician’s best friend! Used for troubleshooting the relay outputs and field wiring to the load. When relay test mode is activated by entering the menu, the selected relay(s) state (on or off) will be held with no timeout until the menu is exited.

DMX PAT Patch each of the 6 relay outputs to any DMX input channel. Full flexibility is provided to manually patch any relay to any DMX channel. First, the relay (R#) output is selected, and then any DMX input channel from 001 to 512 is selected and patched to the selected dimmer.
Page 23
TRIGGER LEVEL Set the DMX trigger level threshold for each relay. Each of the relay outputs can be configured to be triggered on/off at a selectable DMX level from 2% to 98%. There is a 4% hysteresis to eliminate false triggering. The default DMX trigger level threshold is 50% with the relay triggered on at 52% and triggered off at 48%.

10. AUX1MODE Set the auxiliary input 1 mode to trigger relays on, load shed or activate effects. The auxiliary dry-contact inputs are simply a maintained normally-open switch connection between the auxiliary input and common. The auxiliary input may be interfaced with compatible AV control equipment, photocells, occupancy sensors and building management systems (BMS).
Page 25
12. AUXPATCH Configure and patch each of the 6 relay outputs to the auxiliary inputs. The auxiliary patch (AUXPATCH) menu is used to patch each of the six (6) relays to the two (2) auxiliary inputs. When the auxiliary input is activated (maintained connection between the auxiliary input and common), the selected relays are activated according to the auxiliary input mode set in the AUX1MODE and AUX2MODE menus.
Page 26
13. VOLT SEL Select the relay output circuit operating voltage. J-PACK Series relay packs are capable of switching virtually any type of 120VAC, 208VAC, 240VAC or 277VAC loads. The relay pack must be configured for the applicable relay output circuit operating voltage.
Page 27
18. DEFAULTS Set various system configuration settings to the factory default. Press EXECUTE to enter the menu. Press MENU ( ) to scroll through and select which item(s) to default. DMX PAT? Clears the DMX patch and sets as invalid. AUX PAT? Clears patch for both auxiliary inputs.
