The UMD protocol driver file DS0126.xxx (RSE) supports the devices RP1 UMD
(1 display), RP2 UMD (2 displays) and RP3 UMD (3 displays). The system supports
up to 32 UMDs devices with up to 96 displays (if the RP3 UMD is used).
All UMDs are “MPK Bus” devices. The UMDs sit on our message-per-keystroke
“MPK Bus” for control communication. This serial data bus can support up to 32
UMD-series displays daisy-chained on a single serial port of the switcher main-
frame or control panel. Looping connectors are provided to simplify daisy chaining
connections.
