disconnected from the AFS-16 and the operating system will be reloaded.
 RS232 Connector: An RJ-45 Serial Port for connection to your PC, control device,
or external modem. Please refer to Appendix A for a description of the RS232
interface.
 AUX Connector: (Not Shown) A five terminal quick connector, located on the back
edge of the Control Module board. The AUX Connector can be used in conjunction
with the Monitor/Alarm Input feature to generate an alarm when the status of pin 4
changes. In addition, pins 1 through 3 on the AUX Connector can also be used to
switch a connected device On or Off in response to signal changes at Pin 4. For
more information, please refer to Section 7.
Notes:
• The Monitor Input signal (Pin 4) is always measured relative to the signal at
the common ground (Pin 5).
• A "Low" signal should be between Zero (0) Volts and -48 Volts and a "High"
signal should be between +5 Volts and +48 Volts.
 Release Pin: A snap-lock pin that is used to secure the Control Module to the
AFS-16 frame.
 Monitor Input Level Jumper: (Not Shown) A jumper located on the Control
Module board, which is used to configure the AUX Connector for use with the
Monitor/Alarm Input feature. The Monitor Input Level Jumper selects the non-active
state for the Monitor/Alarm Input feature. When the jumper is set in the "1" position
(normally high,) the Monitor/Alarm Input feature can generate an alarm when the
Monitor Input signal goes low. When the jumper is set in the "0" position (normally
low,) the Monitor/Alarm Input feature can generate an alarm when the Monitor Input
signal goes high. For more information on the Monitor/Alarm Input feature, please
refer to Section 7.6.
