RS-232 Interface Ports
The Model 640 TNPP interface card has two DB-9 ports that provide two-way communications
with the network link equipment. Zetron offers a cable (Part No. 702-7211) specially designed to
connect the RS-232 port to a standard 25-pin interface. If a 9-pin connector is preferred, use a
common 9-to-25-pin adapter cable. These should be readily available at any computer store.
Otherwise, use the pinouts shown in Figure 57 to create an appropriate cable. Leads 5-9 do not
require a connection on either end.
