'PROGRAM' + 'ENTER' keys.
NOTE: There are two other modes that can also be entered during the Power On Diagnostics, they are as
follows:
1. To enter the 'Option Board Menu' mode, press and hold the 'REGISTER' + 'CONTROL' keys while
powering on the unit, then release the keys after approximately 8 seconds. This mode is used primarily
for programming the LARC2 Boot ROM and Program Flash Memory during the manufacturing test
process. Refer to the Option Board Menu section of this document for more information.
2. To enter the 'Menu' mode, press and hold the 'PROGRAM' + 'MACHINE' keys while powering on the
unit. This mode is used primarily for programming the LARC2 Boot ROM and Program Flash Memory
when the LARC2 is connected to a 960L mainframe. Refer to the 960L Diagnostics Descriptions
document (P/N 010-13397) for more information.
Debug Port:
The text that is displayed on the LARC2 LCD display in these modes is also sent to the 'Debug' port of the
LARC2 Option Board (when installed). Connecting a (RS-232) serial 'Debug' terminal to the 'Debug' port is
an extremely useful tool for debugging purposes. Another advantage of using the debug terminal is that the
terminal keyboard can also be used to execute the Interactive Diagnostic tests on the LARC2 when the use
of the keypad is not possible or impractical.
During the Power On Diagnostics, diagnostic information is sent to the 'Debug' port of the LARC2 Option
Board (when installed) which is not displayed on LARC2 LCD display as shown in the example below:
(NOTE: In the example below, a PCMCIA Ethernet Card was installed on the LARC2 Option Board, and an
External Keyboard was not connected to the LARC2 'AUX' port.
