How can i communicate from my pc to the ups on the 9 pin serial connection

This devices interface is extremely old technology the 9 pin connector is most likely a rs232 serial interface . If your laptop has a 9 pin rs232 interface you may need a DTE to DCE adapter .
if you do not have this old rs232 port on your laptop I think this device a usb to null modem rs232 DB9 Serial DCS Adapter Cable with FTDI.

What do I need to communicate between my Casio digital diary and my PC?

Most Casio Digital Diary models have a small 2.5mm serial port built into the side of the unit. It can be used to communicate between two Casio Digital Diary units, or with another serial device such as a PC (or a serial printer on some older models).

To connect between two compatible Digital Diary units, you need only a 3-lead crossover cable with a 2.5mm plug on each end, such as Casio's SB-60 or SB-62 cable. You can buy these cables from a Casio accessory supplier such as Windows Link.

To connect to a standard 9 or 25-pin RS232 PC serial port, you need a special Casio-specific adapter cable (more information below). The Casio diary uses its own unique communications protocol, and requires a Casio diary backup program on the PC. You can build your own cable or buy one by mail order, and use it with shareware software such as XLink/Win, or you can buy a kit complete with cable and software such as those sold by Casio or Windows Link

For more information on serial cables, see Cables. For more information on software and kits see What communications packages are available for the Casio digital diary?

Have you tried emailing tech support?

Failing that, and lack of pinout, serial communications can be done with only 4 connections, Transmit and Receive (TX, RX) ground (GND) if you do it with no handshaking. You'll need Data Terminal Ready (DTR) and Data Set Ready (DSR) and or CTS/RTS (Clear/Ready to end). You may have to trial and error it.

Pin 1 - Carrier Detect (CD) - only needed for a modem
Pin 2 - Receive Data (RX) - Cross over with TX
Pin 3 - Transmit Data (TX) - Cross over with RX
Pin 4 - Data Terminal Ready - Cross over with DSR
Pin 5 - Signal Ground (GND) - Goes to other side ground.
Pin 6 - Data Set Ready (DSR) - Cross over with DTR
Pin 7 - Request To Send (RTS) - Cross over with CTS
Pin 8 - Clear To Send (CTS) - Cross over with RTS
Pin 9 - Ring Indicator - Only needed for modem

The protocol is class 2 . Maybe your code reader is no good .
012 GM Class II Communications

Data Link Connector (DLC)
The data link connector (DLC) contains the following serial data links:
• Class II
• Entertainment and Comfort (E&C)
The DLC also provides a power source for the scan tool as follows:
• Unswitched voltage (B+) at DLC terminal 16 (circuit 1450)
• Ground at terminal 4 (circuit 1450) and terminal 5 (circuit 1550)

Class II Serial Data Link
The class II serial data link allows the following modules to communicate data with each other:
• Body control module (BCM)
• Electronic brake traction control module (EBTCM)
• Heater-A/C control (if equipped with RPO CJ2)
• Instrument panel cluster (IPC)
• Powertrain control module (PCM)
• Inflatable Restraint Sensing and Diagnostic Module (SDM).
The Class II serial data link allows a Scan Tool scan tool to communicate with the above modules for diagnostic and testing purposes. The Class II serial data link is located at the DLC connector terminal 2. Terminal 2 consists of the following circuits:
• Circuit 1036
• Circuit 1037
• Circuit 1128
• Circuit 1049
• Circuit 1122
• Circuit 1132
Entertainment and Comfort (E&C) Serial Data Link
The entertainment and comfort (E&C) serial data link allows a scan tool to communicate with the radio or the mobile telephone handset the remote CD player (if equipped). This communication is for diagnostic and testing purposes. The E&C serial data link is located at the DLC connector terminal 14, circuit 835.
PIN #9 goes to the air bag module .

a serial port is a 9 pin (DB-9) connector for serial communication (RS232) used by modems, mouse, etc... In older machines you had a DB-25 (25 pin connector) as well usually situated in the back of the computer near the printer port (DB-25 connector) but femail (25 holes insdead of 25 pins)

Hope this helps!

The Dynex adapter does not have any numbers on it. It was the one that is only about a foot in length and has a square center piece that houses the conversion electronics. Standard 9 pin RS-232 male plug on one end and the standard USB plug on the other end. I purchased it within the last month at BestBuy here in Austin TX.

The 9 pin serial port, dosen;t always have all the "lines" that are in the 15 pin. (obviously) normally ya need Tx, RX RTS, CTS. You need to find out exactly what lines are needed. Make sure via metering that they are all there. Also it may need to cross-over ie: Tx goes to Rx and Rx goes to Tx. Try using a Null Modem. OR try a USB to 9 pin Din serial adapter.

What connector/interface does your PC has
9-pin or 25-pin connector

If it has 9-pin connector: use the following:
DB-9 RS-232 Serial Connection
or
DB-25 RS-232 Serial Connection

If it has 25-pin connector: use the following:
DB-25 Serial Connection
or
DB-25 RS-232 Serial Connection

If you are configuring the computer to use an RS-422A serial port, you need a special cable. Contact the computer or printer network manufacturer to see if an RS-422A cable is available. If no cable is available, contact your computer manufacturer for your computer pin assignments and have a cable constructed.

The default configuration for the serial port on the printer is for RS-232C serial communication. To set the printer to use RS-422A serial communication, change the control panel Serial Menu’s SERIAL setting to SERIAL=RS-422.

hello weave!m just curios if that 9 pin is a serial type connection?then if it is..you shoud find an adaptor for a serial port or any port that fits ur 9 pin connector.if u can find a PCI card that has a 9 pin port..then you can connect..just feed me back for your more details.

As long as the camera is taking pictures and playing back the pictures on its LCD, most of time the camera is OK. Serial communication port of Digital Camera is rarely damaged. If you are using Windows '95, there is a way of verifying the serial communication port. Following are the instructions: a. Open Control Panel from the Start/Settings menu. Double-click Accessibility options, then go to Mouse and activate mouse keys. This feature enables you to use the numeric keypad to move the mouse pointer. (For details please refer to the Help index of Windows 95) b. Turn off the PC and the Digital camera. Remove the Serial mouse from 9 pin connector, then connect Data transfer cable to the 9 pin connector and the other end of cable connect to the Digital camera. Turn ON the PC and the Digital camera. From this point the numeric keypad can be used for Mouse functions. Start the FUJI data transfer software, select COM 1 from the Communication ports within the "Communications Settings" item of the "Camera" Menu. c. Go to "Get images from Camera" of the "Camera" Menu. If you get a blank thumbnail, your Digital camera is communicating to the PC. To receive thumbnails of all pictures go to "Edit", go to "Select All", then click the 3rd Icon from the left. Progressive indicator shows "Receiving thumbnails". In this case the Camera is OK, and the problem is other than with the Digital camera.
