Network Control Module 300 Series Technical Bulletin
Hardware Requirements
WNCSETUP requires the following hardware to run:
• PC or laptop
• cabling - if the utility is run via the:
- RS-232 Port 2 or 3 on the NCM, the cable could be 9-pin
female or 25-pin female on the PC end, based on the type of
PC or laptop used. The NCM connection is 9-pin female. See
NCM Cable Guidelines in this document.
- N1, then the N1 coax cable is required to connect the PC or
laptop to the NCM.
• floppy drive or hard disk
Software Requirements
Running WNCSETUP on the NCM requires the following software:
• Metasys software Release 8.0 or later
• Microsoft® Windows® software
Power On Sequence
The following LED light sequence occurs when you turn on power to
the NCM. (The self-diagnostic LEDs are more fully explained in the
Troubleshooting section of this document.)
!
IMPORTANT: Install the NU-ROM101 or NU-ROM150 before
applying power to the NCM. If either the NU-ROM101 or NU-ROM150 is not
installed when power is applied to the NCM, the NCM DRAM and NOVRAM
may be corrupted. If the NOVRAM is corrupted, replace the NCM.
1. After applying power, the LEDs may sometimes randomly light
during initialization (for approximately 1 second), responding to
commanded positions.
2. An LED (LED 1 through 8) flashes as an indication of the
firmware revision (for example, LED 1 for Revision 1 of the
NCM300 and NCM311, or LED 8 for Revision 1 of the NCM350
and NCM361).
3. Then all LEDs flash simultaneously, followed by each LED
flashing in sequence, starting with the LED closest to the top of the
board (by the N2 connector).
4. The software then executes tests for EPROM checksum and
DRAM read/write, followed by other startup diagnostics. LED 8 is
on during this test.
