Channel Output Configuration
The QS/ES-100M connects to peripheral equipment through RJ-11
connectors, or using the optional adapter cables, male D-25 connectors.
When the RJ-11 connector is converted to a D-25 connector, the conversion
cable must be assembled with respect to either a DTE or DCE
configuration. The standard serial port connections are listed in Figure 11.
