3-5 One-to-one NT Link
High-speed communications can be achieved by providing a direct access
through the use of the 1:1 NT Link between the SRM1 and Programmable Termi-
nal (PT). The RS-232C port can be used for NT Link. A 1:1 NT Link is only pos-
sible with a Master Control Unit that has an RS-232C port (SRM1-C02,
SRM1-C02-V1, or SRM1-C02-V2).
