This section presents the functional operation and concepts of the Nx64-DualMUX. Readers
should familiarize themselves with this section before proceeding to the Installation section.
Feature Summary
The major features of the Nx8-DualMUX are outlined in the following table:
Composite Port Interface (DTE)
Software-selectable interface types: RS-232, EIA-530, V.35*, RS-422/449*, X.21*
*(via cable adapter)
Selectable clock rates: 8Kbps to 128Kbps, in increments of 8Kbps
Internal Clock for local or back-to-back operation
Channel Port Interface (DCE)
Software-selectable interface types on ports 1, 5, 9 and 13: RS-232, EIA-530, V.35*, RS-422/449*, X.21*
*(via cable adapter)
Programmable Asynchronous (RS-232 only), or Synchronous operation on a per-port basis
Async data rates: 1200, 2400, 4800, 7200, 9600, 14.4K, 19.2K, 28.8K, & 38.4K (bits per second)
Synchronous data rates: all async data rates + 16K, 24K, 32K, 40K, 48K, 56K, & 64K (bits per second)
Programmable RTS to CTS delay: 0, 3, 7, 13, 26, or 53 (milliseconds)
