Product Description
Johnson Systems DMX-2PM DMX 2-Port Merger
JSI’s DMX 2-PORT MERGERS combine two DMX512 data lines into one DMX512 universe providing cost-effective DMX input expansion for temporary and hardwired installations. Input DMX data streams can be combined in a “Highest Take Precedence” (HTP) or selected as “Priority” for backup source or automatic lockout applications. Multiple units can be cascaded together for larger installations.
Available in a choice of portable small enclosure or DIN rail for cabinet mounting, these mergers represent the highest quality for the money available.
Features
- Two opto-isolated DMX512 inputs, one opto-isolated DMX512 output.
- All inputs and outputs employ fast acting, “self-healing” fuse protection.
- Inputs can be selected for “Priority” or “Merge” operation.
- Selectable speed choice of “Fast” or “Slow” DMX.
- Power and data receive LED indicators.
- Unique power saving standby (idle) mode reduces power consumption to less than 1 Watt, a “green” power management product.
