SONY PTZ

Many years ago, I used a VideoLabs "ClearOne" gooseneck mounted camera trying to fire up an ActionMedia 2 adapter. Unfortunately, the ClearOne has poor low-light response, and the images had purple speckles...

So after a bit, prices on PTZ cameras came down, making it reasonable to buy one used. A brand that has wide use, good tech support, and uses a industry standard protocol [VISCA] is Sony. Frugal PTZ cameras that use VISCA include the EVI-D30, -D70, and the -D100.

Note: Different models of the EVI-Dxx series can vary in supported command codes.

ALPHA version of VISCA protocol PS/2 RS-232 port control app 

WBST has an -- ALPHA -- version of a SONY VISCA protocol PTZ camera controller via an RS-232 serial port.

"The test program is still too basic (excuse the pun) for publication. It needs someone with the hardware to do some testing to verify operation. Only then can we look into a proper TSR or device driver to operate in co-existence with a video display application, if that was the final intended purpose."

EVID70_T.DSK  11/01/2019  PS/2 RS-232 serial port control software for VISCA compliant PTZ   This is the bootable QBASIC test application diskette.

EVID70_T.BAS Versions  You can try different versions by adding EVID70_T.BAS to the EVID70_T diskette. Rename the original EVID70_T.BAS before copying the newer version to the EVID70_T diskette...

EVID70_T_03.BAS 10/21/2019
EVID70_T_04.BAS 10/23/2019
EVID70_T_05.BAS 11/01/2019 <<<   Latest version

EVID70_T versions prior to 03 were removed. They are alpha code, and are not reliable.

WBST:
"Still refining a little and will send *revision* (not version, yet. Would be .100 for Version 1 Release 0 Revision 0) 005 and a refresh of the .DSK image (clean up etc.) as soon as feasible, to include the EVID70_R.BAS "D70 emulator" and all revisions 003 thru 005 (all in text format, due to QuickBASIC 4.5's Fast Save+Load format problem) too."

    Contains WinImage 9.00 32 bits Intel/AMD version in English for Windows Windows XP, Windows 2003/2008 server, Windows Vista, Windows Seven, along with the WinImage self-extractor.

File [choose *.DSK], then choose Disk > Write Disk. Created diskette has 1.0MB used [1,048,576] and 399KB free [409,088].

Note: The DSK won't fit if you SIMMply copy it to a floppy

Here is where the program could be clearer by adding "A:" or "Floppy" to the menu line.



What do I run to get EVI-D70_T.BAS to run?
WBST said:

After booting to the A:\> prompt, enter TEST to start. Wait.....
.............................
while QB 4.5 loads and then loads EVID70_T.BAS and the QBSER.QLB library.

Then, initially, press F5 to try it out. If it seems to hang after more than 3 seconds pressing CTRL+Break should return you to the QuickBASIC 4.5 screen.

Model 90 DB9 Serial Port Setup [Planar Device 6 – Serial Port No. 2]  

Some clarification, the "Serial Port" in "Built In Features" is the DB25. Es la verdad, as I am using the Sony DB9 VISCA cable [SONY P/N RC9P3 or RC893/1].

Note: Type 1 and Type 2 serial controllers are fixed to Serial 1 at 03F8 IRQ4, or Serial 2 / 02F8 IRQ3. Type 3 serial controllers can choose between IRQ 3 or IRQ 4.... If you select other than Serial 1 or Serial 2, the I/O addresses WILL change!

Arbitration (only required by DMA access) is not implemented in the package. Those settings aren't used or required.

EVID70_T.BAS version 03 Output



Version 3 actually works... I was so surprised that I didn't even try using the arrow keys until Lorenzo told me his was moving. Both the Numeric pad AND the four arrow keys all control the PTZ.

When using the test program, do not hold the arrow down, just press and release. The test program at this time is biased towards "proof of concept" where you send a command, the PTZ acknowledges, and the PTZ performs the command. It is "laggy".

Test program Useful environment usage: 

To start EVID70_T.BAS, boot with EVID70 floppy, Alt-R at main screen, choose Start.

S Set Configuration
R Run Main Loop [Note: use X to exit]
Q Quit [application]

S Set Configuration brings up:

S Serial Port [1 or 2] Choose SERIAL 1 or SERIAL 2. Disable any Arbitration Levels.
B Baud Rate (9600 or 38400] Note: Bottom switch on EVI must agree!
X Exit setup

Errata -
To be implemented later, not in EVID70_T_03.BAS

F6 - rotates thru the 2 or 3 (if Help window active) windows:
Program -> Immediate (-> Help) -> Program ...

Esc - dismiss Help window (Tab works thru clickable links, first char of these also does something similar)

Shift F1 - Activate Help window

F4 - Display program output screen -  any key to exit back (unless input req.d)
F5 - Run program
F8 - In program window, single-step each BASIC line
F9 - In program window, set breakpoint at cursor line

Sensor for the Remote Commander  


IMAGE FLIP switch  
Flips the image upside down. Normally set this to OFF when you use the camera. When the camera is attached to the ceiling, set this to ON. When you switch this, the pre-set setting is returned to the initial setting. It takes about 7 seconds for the image displayed to respond to the setting change.

IR SELECT switch  
Selects the camera number when you operate multiple cameras with the same Remote Commander

VISCA RS-422 connector   
A VISCA RS-422 connector plug is attached to the unit at the factory.
   Note: See VISCA Removable Terminal Block
   Note: Do not make VISCA RS-232C and RS-422 connections at the same time, as this
may cause malfunctions.
