HARDWARE INSTALLATION/CHECKOUT/SERVICE
Appendix B
This appendix contains hardware information useful in the installation, checkout, and service of
the Host Processor-to-CG data link.
B.1 CG INSTALLATION, SERVICE AND TESTING
B.1.1 CG Installation
General information on site planning for and installation of TDC 3000
X
LCN Nodes such
as the CG is found in the LCN Site Planning Manual, the LCN System Installation Manual,
and the LCN System Checkout Manual.
B.1.2 CG Service
General information on service for TDC 3000
X
LCN Nodes such as the CG is found in the
Five/Ten-Slot Module Service publication.
B.1.3 CG Testing
Like all LCN nodes, the CG contains built in firmware and software tests. Additional
installation and off-line troubleshooting tests of the CG are provided by the Hardware
Verification Test System (HVTS). Specific HVTS test programs that apply to the CG are
• Local Control Network Exerciser (LCNX)
• Memory Exerciser (MEMX)
• Communications Line Interface (CLIF)
See the HVTS Reference Manual for use information and restrictions.
Two of the Communications Line Interface board tests require special equipment. CLIF
test 13 requires a loopback cable, and test 14 requires two loopback connectors.
For testing of data link transmissions in the normal (non-HVTS) operating environment,
the use of a Data Analyzer is recommended. Typical of these devices are the AR 45000, the
HP 4955A, and HP 4953A. See Figure 5-1 for a simulated data analyzer output of
host/CG communication.
B.2 CABLES AND CONNECTORS
The following paragraphs summarize the pinning requirements for both RS-449 and RS-
232C cables, including the test cables and connectors required by HVTS.
