August 3, 2006 Chapter 5. Compact ANPOS Keyboard Keyboard/pointer symptoms 135 CANPOS Keyboard components - removing and replacing 137 CANPOS keypad assembly 138 CANPOS keyboard logic card 141 CANPOS keyboard with MSR 142 This chapter contains repair and usage information for the CANPOS Keyboard. The CANPOS Keyboard provides a QWERTY layout, an integrated pointing device, a numeric keypad, and 32 programmable keys. Key caps can be inserted onto the programmable keys to show a new key definition. The 32 programmable keys are programmed by the customer using the CANPOS Keyboard Utility program. See the SurePOS 500/600 Installation and Operations Guide for more information on the CANPOS Keyboard Utility program. Keyboard/pointer symptoms Notes: 1. Two PS/2-style keyboard ports are provided, but only one may be used at a time. Attaching two keyboards at the same time will cause keyboard failure. 2. The redesigned cap (with the textured surface) for the keyboard pointing device (joystick) is a consumable item: the customer is responsible for cap replacement. If you have this style cap, replacement caps can be purchased by calling 1-800-IBM-CALL (1-800-426-2255) in the U.S. and Canada. Customers outside the U.S. and Canada should contact their IBM representative. The part number for the caps is: 30R0037. Use Table 11 to determine the failing CANPOS keyboard FRU. Table 11.
