Note: Either cable connectors or interlock covers must be installed to allow the 
generator to operate.
TO CONTROL THE GENERATOR THROUGH A USER PORT
Apex User port options are identified by PIN position 8, and they are discussed 
individually in “Apex User Port Options” on page 4-2. Use the generator’s PIN and 
Table 1-1. on page 1-4 to identify the appropriate User port section of the manual for 
your unit.
To connect to the User port, install the appropriate I/O cable (cable requirements are 
identified in the individual User port sections).
TO CONTROL THE GENERATOR THROUGH A HOST PORT
Apex Host port options are identified by PIN position 6, and they are discussed 
individually in “Apex Host Port Options” on page 4-37. Use the generator’s PIN and 
Table 1-1. on page 1-4 to identify the appropriate Host port section of the manual for 
your unit.
To Connect to an Apex Host Port:
1. Ensure that the required User port inputs are satisfied. The required User port 
inputs are identified under the Satisfying Minimal Requirements section for your 
User port. To determine which User port you have, see the information for PIN 
position 8 in Table 1-1. on page 1-4.
2. Connect and secure the appropriate serial cable to the Apex unit and the host 
(cable requirements are identified in the individual Host port sections).
