Specifications - Tascam DV-RA1000HD Specification

1. Overview
The DV-RA1000HD (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".

*1: Impress voltage complied with RS-232C standard to Rx Data.
*2: DV-RA1000HD doesn't have RTS/CTS terminals for loop-back in this connector. Make sure the
specifications of external controller and if necessary, please have the loop-back circuit outside of
the DV-RA1000HD.
TASCAM DV-RA1000HD RS-232C Protocol Specifications
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.
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
< 2V
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.
Logical "1" = < -3V
