A1) The molded plastic connector on the serial tower is fairly tight. It can do damage to a weak computer connector. A solution is to replace the cable with a standard ‘straight through’ 9 pin female to 9 pin female serial wire available at most computer stores. Bring the tower with you to make sure the new cable will fit properly. A2) Purchase a serial extension cable. A3) Replace with a USB tower. Q11.15) Can my team use NQC, Java, or … A) No. The only legal languages are RIS, and RoboLab of any version. Q11.) The RCX sometimes does not behave properly. A) One possibility is mismatched firmware. If you are using RIS and RoboLab or different versions of RIS you may experience this problem. You may have downloaded an older less capable version of the firmware into the RCX from one program and trying to use advance features of the other. The solution is to pick one language and reload the firmware from that program only.
