Switch One Settings 2185 a | Telenetics manual

Telenetics 2185

In this application, the main channel of both 2185 A and 2185 B are con- nected via a straight-through cable with the 2185 A main channel set to DTE and the 2185 B main channel set to DCE. The data rate is 1.2 kpbs asynchronous so clocking is not an issue. Subchannel one of 2185 A is connected directly to the local host computer and is set to DTE. Sub- channel two is connected via a modem link to the backup computer installation and is set to DCE.

All five subchannels of 2185 B are connected to external devices with subchannels one, two, and four set to DTE and subchannels three and five set to DCE.

The following tables show the switch settings for 2185 A first and then for 2185 B.
