1. Introduction
(1) The VTR can be operated by commands when the RS-232C interface is used.
(See command table on page 79 Ð 81.)
(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 ÒRS232C SELÓ must be ON.
If the above conditions are not met, [ACK] + [STX]ER001[EXT] 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
ÒRETURN ACKÓ.
