The RCP-3500 is the successor model of the RCP-1500, but keeps the same dimensions and the same basic functions.The RCP-3500 remote-control panel incorporates direct operation switches and a touch panel, and offers improved visibility with a higher-resolution and brighter LCD display. These factors make it a remote-control panel that offers both ease of operation and multi-functionality that compares favorably with the MSU. The iris and master black adjustment block use joystick-type control. Up to four units can be mounted in a 19-inch EIA rack.
