RS-232C interface

1.Introduction

(1)The VTR can be operated by commands when the RS-232C interface is used.

(See command table on page 60 – 62.)

(2)Conditions for acknowledging commands from RS-232C interface

The front panel REMOTE/LOCAL switch must be at REMOTE. The setup menu item No. 204 “RS232C SEL” must be ON.

If the above conditions are not met, [ACK] + [STX]ER001[ETX] is returned to the external unit.

Whether the [ACK] code is returned depends on the setting which has been selected for setup menu item No. 209 “RETURN ACK”.
