1	1	If you are experiencing trouble communicating using the serial port or a usb to serial cable these are almost always issues with the PC. Here is a list of some of the most common problems. These suggestions pertain to the SSC-32 communications AND the Bot Board II programming.

4	4	The green LED on the SSC-32 is a status indicator, not a power light. If this LED does not illuminate then you have a power problem. When power is first applied the LED will light up steady telling you it’s 99% functional. The LED will go out after it has received its first byte of data, and then blink after that when it’s receiving data. This will happen even if the baud rate is wrong. It’s a useful tool for troubleshooting the communication system.

6	6	Note: LynxTerm, RIOS, SEQ and PowerPod all send commands to the serial port continuously when first opened. It’s possible that the LED is on for such a short time it appears to never go on. Remove the serial connector and try again.

14	14	This is a sure indication that your program is not talking on the right serial, or “com” port, or the com port is defective, or the serial cable or USB to serial cable is defective, or the serial port enable jumpers are not installed on the SSC-32.

16	16	Normal DB9 serial ports, indicated by the 9 pins sticking out of the D shaped metal part are normally numbered as com1 or com2. Try changing the com port to a different number. If you don’t have a serial port it’s easy to add one.

20	20	We recommend only high quality name brand adapters. With these devices you literally get what you pay for, so don’t skimp. Look for cables that use the FTDI driver chip if possible. We highly recommend the FTDI UC-232R-NE ChiPi cable 115. Others have reported good results with the following cables. Belkin F5U409, BAFO BF-810, I/O Gear GUC-232A, Keyspan USA-19HS, Dynex DX-UBDB9, etc. Although these adapters have worked in the past, with manufacturer changes, and new operating systems emerging, there is no guarantee they will continue to do so. The only USB to serial adapter we know will work for sure the the FTDI.

34	34	Make sure the receive and transmit transfer sizes are 4096, and change the latency to 1. Click ok then ok. Then close the rest. The latency is the delay before sending data. If it’s too long problems arise.

36	36	If you plan to do a lot with this hobby and want a trouble free interface then install a real serial port as illustrated here. USB to serial cables do work, but some can be finicky to optimize for the best operation.

44	44	Check the power mapping for the USB ports. The mapping defines how much power each port has available to it. Some USB devices will take up to 500mA of power. Some mapping actually shares this 500mA with 4 or more ports. Insufficient power can cause problems. Some users mention they had to use a powered hub to get the adapter to work, especially with laptops.
45	45
46	46	Some PC’s use a serial channel for IR communications. Apparently it’s possible for this same channel to be selected by a USB to serial cable. A user reports changing the default com port from 6 to 7 fixed a speed issue.

56	56	One thing that is not apparent is that the serial port is only available to one program at a time. Usually the first program that uses the serial port will not allow other programs to use it. After the program is closed the serial port will be available again. You can also add an additional serial port if you want to, for example, be able to program the Atom and connect with the SSC-32 at the same time.
