About this Manual
This manual will guide you through the installation, setup and wiring of your DDC Series Wall Clock. This
manual covers the four available DDC Series models. The available models and their descriptions are:
DDC2-RS / DDC4-RS Equipped with a 2-inch or 4-inch display, these models can operate as a stand-
alone, a secondary clock to virtually any master controlled system or can be
synchronized with the RS485 signal from the Lathem LTR4-512 or LTR8-512
Master, LTR0 mini:master, Terminal Manager Software* or the OMNI:CHRON
Time Clock.
DDC2-RS-24 / DDC4-RS-24 Same as above, models with the "-24" suffix have an optional power
transformer that allows for 24VAC operation. These models are
designed to be powered from an external, 24VAC-power supply for use
in installations where local 115VAC power may not available.
* The Lathem SWIFT-485 plus is required for RS485 synchronization.
