1. Introduction
(1) The VTR can be operated by commands when the RS-232C interface is used.
(See command table on pages 95 Ð 97.)
(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.

Communication speed 300/600/1200/2400/4800/9600
Bit length 7 bit/8 bit
Stop bit1 bit/2 bit
Parity bitNONE/ODD/EVEN
ACK code ACK code returned/ACK code not returned

The ACK code is what is returned from the VTR to the controller when data has
been successfully sent from the controller.
The underlining indicates the factory settings.
Any changes to the settings can be made using the setup menu items listed below.
