SS-R200, SS-CDR200 RS-232C documentation - Tascam

RS-232C Protocol Specifications Rev. 1.00SS-CDR200/SS-R2001. OverviewThe SS-CDR200/SS-R200 (“controlled device”) can be controlled from an external device (“externalcontroller”), such as a computer, through a serial RS-232C connection.2. Specifications2.1. Electrical SpecificationsStandardJIS X-5101 (equivalent to the former JIS-C-6361 and EIA RS-232Cstandards)Note that this is not compatible with the RS-422 used in professional VTRs.Impedance at receiverWhen measured with an applied voltage between -3 V and +3 V or between-15 V and +15 V, the DC resistance is between 3 k ohms and 7 k ohms.Total load capacitance is 2500 pF or less.Open circuit voltage at transmitter 25V or lessOpen circuit voltage at receiver 2V or lessSignal voltageWhen the open circuit voltage at the receiver is 0 V, the signal voltage isbetween -5 V and +5 V or between -15 V and +15V against a loadimpedance between 3 k ohms and 7 k ohms.Signal discriminationLogic “1”: -3V or lessLogic “0”: +3V or more2.2.
