CHAPTER 1 - OPERATON
The Patton MSDs are network enhancement accessories intended for DCE sharing
applications. The Patton MSDs allows up to eight terminals or DTE devices to share
a single point to point or multi-drop polled communication link.
The Patton MSDs allow for immediate expansion of a system without the
requirement of additional Modems or communication lines. All MSDs are protocol
transparent and operate in synchronous or asynchronous environments at rates up
to 38.4Kbps. Clocking is provided by the attached DCE device on the Master Port.
The Patton MSDs have Anti-Streaming capabilities that include selectable time-outs
depending on your system transmission speed, and a setting to disable antistreaming for large data block transfers. No special cables or adapters are required
for normal DTE-DCE operation. All interconnects are made via industry standard
female DB-25 connectors located on the rear panel of the units. A linear 110/
220V, UL, CSA and TÜV approved power supply is internal to the unit.
