Figure 8 CONNECTOR PL1 PIN DESIGNATIONS
Notes to figure 8:
1. 'No Conn' means no connection to this pin
2. Chan 1 (channel 1) is the output of DAC 1, chan 2 the output of DAC 2 and so on.
3. Analog output channels should be referred to their own ground pins (AGnd)
4. Counter connections are available via jumpers J11, J12, and J16 to J20.
5. Ext (external) Voltage must be in the range +12 to +30 (max) volts DC.
6. Counter connections and external voltage inputs should be referred to Gnd (digital
ground)
3.2 EMC Considerations
In order to maintain compliance with the EMC directive, 89/336/EEC, it is mandatory that the
final system integrator uses good quality screened cables for external connections. It is up to
the final system integrator to ensure that compliance with the Directive is maintained.
Amplicon Liveline offers a series of good quality screened cables for this purpose. Please
contact our sales staff.
