9.1.1 DESCRIPTION OF RS-232C COMMANDS

A
With the PDP-5000EX/PRO-FHD1, the serial port is commonly used by the RS-232C and SR+ connectors. Although the
setting upon shipment is RS-232C, it can be changed to SR+, using the Home menu. If SR+ is selected, to use the RS-232C
commands during servicing to control the unit the setting must be returned to RS-232C.
How to switch between SR+ and RS-232C
There are two ways to switch: (1) by using the remote control unit during Standby mode, and (2) by using the Home menu.
(1) Switching by using the remote control unit during Standby mode
• From SR+ to RS-232C
B
With the unit in normal Standby mode, press a key other than the Standby key. Then within 10 seconds, hold the
Volume + (or -) key pressed for 3 to 10 seconds.
Then hold the sprit key pressed for 3 to 10 seconds. Then within 3 seconds, press the Enter key.
The Standby LED flashes twice.
Then the setting is switched to RS-232C, and the baud rate becomes 9600 bps.
• From RS-232C to SR+
With the unit in normal Standby mode, press a key other than the Standby key. Then within 10 seconds, hold the
Volume + (or -) key pressed for 3 to 10 seconds.

About RS-232C commands during Standby mode
During Standby mode (while the power to the main microcomputer is off), RS-232C commands (excluding some, such as
PON) are not valid. If you wish to send invalid commands, such as DRV, during Standby mode, proceed in the following way:
During Standby
E
ZACS00 (Although this is a command for aging, it is used for
starting up the main microcomputer, in this case.)
(Within 10 seconds)
DRVS00 (To turn the drive off)
(Within 10 seconds)
