The RB-DS2R is a remote panel for controlling up to 4 separate RB-DS2 units from a single 1U 19” rack-mount panel.

The unit has 4 rotary switches, each with 8 available selections numbered 0 to 7, used for selecting the delay time in frames. On the rear of the unit are 4 x 15-way D-type connectors used for connecting directly to the remote input of 4 x RB-DS2 units. The RB-DS2R is a passive unit, i.e. there is no power supply.
