Caution
All Vanguard 650 Series devices should be used in environments designed for
computers and electronic equipment. In areas susceptible to lightning, take
precautions to prevent damage to electronic equipment. Contact your telephone
company, an electronic accessories vendor, or Hydro Electric operator for
information on lightning protection equipment. Customers experiencing problems
caused by surges from lightning have eliminated such problems by installing
appropriate surge suppressors on power and data lines connected to Vanguard 650
Series devices.
Cable Clearance/
Air Circulation To avoid overheating the unit’s circuitry, you should never place anything on top of
the unit. It is also recommended that you leave at least 1 inch (2.5 cm) of clearance in
front of the front panel to allow you to see the unit’s LEDs, and allow at least 2
inches (5 cm) in back of the unit for interfacing cable clearance.
ISDN Cable An RJ-11 ISDN cable is supplied with your Vanguard 650 Series. The pinouts for the
cable are given in the “ISDN Cable Description” section of Appendix A,
Specifications. The cable is available for the U interface (RJ11) or the S/T interface
(RJ45), and the part numbers for the cables are U:61766-02 and S/T:61545-01,
respectively.
Data 1 and Data 2 The Data 1 port is an RJ45 connector that can be used for a partial EIA 232 or Async
modem connection (on the 652/654) or a partial EIA 232 Sync/Async connection
(on the 651/653).
The Data 2 port is a DB25 connector, which is an EIA 232 connection on both units.
Data 2 is also used as the physical CTP interface connector to the PC, Macintosh, or
workstation.
The pinouts for the cables used for Data 1 and Data 2 are given in the “Data 1 and
Data 2 Cable Descriptions” of Appendix A, Specifications.
CTP Cable Optional DB25 (male) to DB9 (male) OR RJ45 to DB25 cables, for access to the
Control Terminal Port, are available. The serial ports on most personal computers
require DB9 connectors.
