Setting the RS-232 Communications DIP Switch
Use the 8-position DIP switch to set the communication parameters. Set the parameters with the
combination of ON and OFF positions. The following table describes the communications DIP
switch settings:
AXC-EM Specifications (Cont.)
AXlink Status LED The green LED (CR1) on the front end of the card indicates AXlink status, as follows:
• One blink per second indicates power is active and AXlink communication is
functioning.
• Two blinks per second indicate that the devices specified in the master program do
not match the devices found.
• Three blinks per second indicate an AXlink communication error.
• Full on indicates the following:
•There is no AXlink control or activity, but power is on. (For example, another
AXC-EM may have control of AXlink.)
•The Axcess program is not loaded.
To ensure the integrity of your Axcess program, you can use two AXC-EMs, each loaded with the
same program. Should the primary AXC-EM's control of AXlink be interrupted, the secondary
AXC-EM will automatically take control.
