Overview
The CONTROL I/O connector (RS-232C) on the HS-8 enables you to control the HS-8 from a computer or
other external devices. In this document, the HS-8 is referred to as the "controlled device," and the external
device that controls it is referred to as the "external controller."

*1: A voltage that satisfies the RS-232C specification must be applied to Rx Data.
*2: RTS/CTS is loopback-connected within the controlled device. If RTS/CTS control is used, consider the
design of the external controller.
JIS X-5101 (equivalent to former JIS C-6361 and EIA RS-232C)
(Not compatible with the RS-422A used in professional VTR units)
When measured with an applied voltage of between ±3 and 15V, the DC
resistance is between 3KΩ and 7KΩ.
Total load capacitance is 2500pF or below.
25V or below
2V or below
When the open circuit voltage at the receiver is 0V, the signal voltage is
between ±5V and ±15V for a load impedance of between 3K and 7KΩ.
