TASCAM CD-01U/CD-01U PRO RS-232C Protocol Specifications

1. Overview

The CD-01U/CD-01U PRO (here referred to as “controlled device”) functions can be controlled using a serial RS-232C connection from an external device, such as a computer. Such a device is referred to here as the “external controller”.

2. Specifications

2.1. Electrical Specifications
Conforms to standard		JIS X-5101 (equivalent to former JIS-C-6361 and EIA RS-232C
		standards) Note that this is not compatible with the RS-422 used
		in professional VTR units.
Impedance at receiver		When measured with an applied voltage of between +/-3 V and
		+/-15 V, the DC resistance is between 3 kohm and 7 kohm .
		Total load capacitance of < 2500 pF
Open circuit voltage at transmitter		< 25V
Open circuit voltage at receiver		< 2V
Signal voltage		When the open circuit voltage at the receiver is 0 V, the signal
		voltage is between +/-5 V and +/-15 V against a load impedance
		of between 3 kohm and 7 kohm .
Signal discrimination		Logical “1” = < -3V
		Logical “0” = > +3V
2.2. Communication format
Circuit type		3-wire, Half-duplex
Transmission type		Digital binary serial
Data speed (baud rate)		9600/19200/38400 bit/sec
Word length		8-bit
Parity bit		None
Stop bit		1 bit
(* Word length, parity bit, and stop bit of CD-01U are fixed.)
2.3. Connector pin-out
Connector	D-sub 9pin female (Inch screw thread)

Terminal pin-out and input/output signals
