The MDB9-TB5+ is a male DB-9 to 5-position terminal block adapter. It was specifically designed for non-standard control ports like those found on AMX & Crestron control systems. The MDB9-TB5+ provides separate connection points for the five signals (RXD - Pin 2, TXD - Pin 3, GND - Pin 5, RTS - Pin 7, and CTS - Pin 8) that these control systems use for RS-232 control. Please note that a female adapter is required to plug directly into most controllers. | Specifications and Features | Male DB-9 connector | 5-Position terminal block accepts 16-24 AWG solid or stranded wire | RoHS compliant | Cable strain relief | Connection points are labeled with signal abbreviations and pin numbers | Supports 3-wire and 5-wire RS-232 cable configurations | Supports non-standard AMX & Crestron control ports | No soldering or crimping required | Cost effective and reliable cable termination | Machine screws secure adapter to device | Dimensions - Height .62in (15.7mm), Width 1.22in (31.0mm), Depth 1.94in (49.3mm)
