The industry standard Null Modem connection is as follows:įor more information on Null Modem Cables click here Signal NameĪlso, the standard gender of the Null Modem cable 9 Pin D-Sub connector is female on both ends. Therefore, when we use the industrystandard Null Modem cable, pin 1 is pulled up to a + voltage by the pin 1 to pin 4 connection in the cable, and the Compax3 is ready for RS485 communication. In fact, pin 4 is pulled up to a + voltage internally. As per the X10 pin out in the Compax3 User Guide, pin 4 is reserved for the RS232 connection. If 5 Volts is present on pin 1 of the Compax3, it automatically switches to RS485 mode. The Compax3 uses pin 1 of the RS232 connector, X10, to determine if the communication will be RS232 or RS485. If a !FF or similar response is returned, the Compax3 didn't like the command.ġ0) Are you using an industry standard Null Modem cable provided by a non-Parker supplier? The problem with the standard Null Modem cable has to do with the fact that pin 1 is connected to pin 4 of the 9 Pin D-Sub connector of the cable. By turning the motor, you can change this.
Hit, they type "o680.5" (where the first digit is a lower-case "oh") and hit again. You won't be able to see what you type or any prompt. This adapter gives a 9pin com port output a null modem crossover cable is still necessary to connect from the adapter to the Compax3.**ĩ) Set up HyperTerminal for a Baud Rate of 115,200 with 8 bits, 1 stop bit, and no Parity. Specifically the Keyspan USA-19HS does not work with C3 ServoManager software.
The only adapter we know works for sure in Windows 7 and Windows 10 uses the FTDI chipset.

Check the ATEN website for the latest drivers and be aware older adapters may have chipsets that are incompatible with 64bit Windows OS. Other adapters with ATEN chipsets have shown varied compatibility and may not work or fail after connection. Previously recommended was BAFO BF-800 (25-pin RS232 version) and the BF-810 (9-pin RS232 version) which does work on Win XP and prior but the drivers do not work on Windows 7 (Win7). The tested (by Parker EMN) USB to Serial adapter we recommend is the Cables Unlimited part number USB-2920** (available on This adapter has the FTDI chipset. Either the IEC Debugger Tool, the IEC Logic Analyzer (within the Debugger), or the Optimization Tool (includes the O-Scope and Status Display) can be active (scanning the drive)at one time, however, all three may be open on your PC.Ĩ) Are you using a USB to Serial Port adapter? Parker has found that some USB to Serial adapters do not work with the C3 ServoManager. You can verify the COM port setting in the C3 ServoManager by referring to item 3 in this FAQ.Īlso, only one resource within C3 ServoManager can be using the COM port.

Therefore, successful communication is possible, but the additional connections add robustness to the communication.ħ) Is the COM port available or does another resource have the COM? Please verify no other programs on the PC are using the COM port that the C3 ServoManager is trying to use. However, only 3 wires are required for communication - Tx, Rx, and GND (Ground). Are the LED's illuminated (on or blinking, red or green) on the front of the unit? If the Compax3 is only supplied the AC Mains voltage (AC voltage to connector X1) the LED's will NOT illuminate and communication is not possible.Ħ) Is the RS232 cable wired properly? The recommended cable pinout can be found in the Interface Cable section of the Compax3 User Guide. Is the 24VDC powered? To communicate, an external 24VDC supply must be provided and wired to to X4/1 and X4/2 on the Compax3. Select the COM Port(RS232/RS485)., and verify the COM Port setting is the port you want to use.ĥ) Is a 24VDC supply connected to X4 on the Compax3. Are you trying to connect at a different baud rate other than 115200? The RS232 communication on the Compax3 is fixed at 115200.Ĥ) Is the COM port properly configured in the C3 ServoManager? To verify that the correct COM port (the port on your PC) is chosen, please go to the Options pulldown menu in C3 ServoManager. For details see item 10 below.Ģ) Is the RS232 cable connected to the correct COM port on the PC? Is the RS232 cable connected to X10 on the Compax3?ģ) Are you trying to use RS485 communication with the C3 ServoManager? The C3 ServoManager must use RS232 communication only. Remove pin1 with snips and cycle power on the +24vdc on the Compax3. If it is, the Compax3 will autodetect in rs485 mode. 1) If not using the Parker green serial cable SSK1/02, make sure pin1 is not connected to the PC.
