Control Ports And Indicators; Relays - AMX MCP-106 Instruction Manual

Control Ports and Indicators

The following sub-sections describe each control port on the Massio ControlPads. Refer to Overview section on page 13 for the
component layout of the rear panels of each type of Massio ControlPad.
RS-232
The Massio ControlPads features up to two RS-232 300-115,200 baud connector ports so you can connect up to two serial devices
to the ControlPad. The MCP-106 features one RS-232 connector; the MCP-108 features two connectors. The serial connectors
comply with EIA-232-F signal levels. The RX line supports polling for RS-232 devices for statuses such as power status, input
status, and lamp hours, so that this information can be provided to RMS.
NOTE: Massio ControlPads do not support RS-422 or RS-485 communications to devices.
