Using the service port of a Sanyo PLV-Z4

The Z4 has a serial interface called service port. Connected to the serial port of a PC this offers the possibility to remote control nearly all of the projector's functions.

The connection cable

If you don't own the original service port cable from Sanyo it is easy to build one yourself. It is only an adapter from Sub-D to MiniDIN. The pinout is given below.

8pin MiniDIN

8pin MiniDIN pinout (view at plug)

Service-Port	<->	RS-232
Pin 1	<->	Pin 3 (TXD)
Pin 6	<->	Pin 2 (RXD)
Pin 5	<->	Pin 7 and 8
Pin 4, 7 and 8	<->	Pin 5 (GND)

The Beamer-Commander

I wrote a little console-application which sends all commands I know from a Windows-PC to the projector. If anyone knows more commands, please mail me and I will add them to the tool.

Usage

Just call the Beamer-Commander executable from the command prompt. Give the name of the com-port as first parameter and the command to send as second.

Change standby-mode

The Sanyo PLV-Z4 has two standby-modes. Normal standby and super standby. When in super standby the projector doesn't listen to commands from the service port. To use remote "power on" and the "mananged power off" the projector has to be set to normal standby mode.
Enter service menu and set normal standby-mode:

Press MENU and INPUT until a "S" appears on the screen.
Press UP and DOWN until the service menu appears.
Select group 100 (OK increases group number, MENU decreases number)
Select menuitem 4 (UP increases item number, DOWN decreases)
Set data to 0 (use LEFT and RIGHT)
Press POWER to exit service menu.
