➀ For network interconnection cable,
use Belden 9463 or Cutler-Hammer
IMPCABLE.
➁ When interconnecting devices, tie
shield drain wires together for shield
path continuity.
➂ Connect the shield path to a solid
earth ground at one point only.
➃ On last device in network, tape shield
drain wire back upon cable.
➄ Use a 1/2 watt carbon or metal film
resistor at each end of the network
as an end of line termination resistor
(EOLTR). EOLTR should be 100 ohms
for 9600 baud communication rate
networks or 150 ohms for 1200 baud
communication rate networks.
➅ Network interconnection to computer
requires use of an IMPACC master
(CONI or MINT).
➆ Devices without built-in communica-
tions require network interface module
(PONI).
For detailed network wiring specifications,
call the automatic fax retrieval system
(FRED) at 412/494-3745 and request
document 17513 or contact the
Advanced Products Support Center.
