The '483' is slew rate limited which Maxim claims reduces errors caused by improperly terminated lines. It may require additional power supply bypassing or other modifications to the circuit. The unit converts any consecutive 24 DMX channels to 0 to 10 volt output. The switch is mounted on the front panel along with power, signal, and output 1 mimic indicators. The DMX in and through connectors and the female DB-25 output connector are located on the back panel.
All connectors feature gold plated contacts.
The output pinouts are easy to remember with the pin number equaling the channel number, pin 25 being common. The DMX512 input is optically isolated from the outputs and is protected against miswiring up to 120 volts. A test feature allows bringing any output to full by setting the front panel switch to 601 - 624.
