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.
