contact AE Global Support or your AE sales representative. (For contact information,
see “AE Customer Support” on page 6-11.) AE can also provide a simple host
software for this port. For information, contact AE Global Support.
Note: Before controlling/monitoring the Apex generator through this port, you need
to ensure that the required User port inputs are satisfied and that the control is
properly set. 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.
The control mode is usually set to the User port as default when this host port
option is installed. To change the control mode to host, see commands 14 (sets
control mode) and 155 (reads control mode) in the Command Set for the RS-
232, AE Bus Host Port on page 4-45. The control mode setting is stored in
volatile memory so it will need to be set whenever the AC input is powered up.
The RS-232, AE Bus Host port is a 9-pin, female, shielded, subminiature-D
connector.

The signals available at the RS-232, AE Bus Host port conform to the RS-232
interface standards. Each generator is factory preset for a baud rate of 19.2 kb and
Table 4-4 describes the RS-232, AE Bus Host pin signals.
To Connect the Computer to the Apex unit:
Use a standard RS-232 cable that is no longer than 50 feet in length. This cable has a
9-pin, shielded, female, subminiature-D end and a 9-pin male, subminiature-D end.
AE does NOT supply a cable. If you do NOT have the appropriate cable, you can
purchase a standard serial cable at a local computer or electronics store.
Note: The cable must be intended for use between a computer and a peripheral, that is
a cable that is wired straight through (pin 1 on one connector is connected with
pin 1 on the other connector, pin 2 is connected to pin 2 and so on.) A cable
meant to create an interface between two computers will NOT work in this
connection.
Note: To reduce EMI, avoid routing the cable close to ac input or dc output cables.
