Issue:
The 394 controller front panel led displays message H1 15.
Cause:
The connection with the Host computer has been lost or broken.
Solution:
When the 394 controller front panel displays message H1 15, this message is generally caused when there is a break in communications with the host computer,and the remote office .
The message can be broken into two parts.
H1 (the host is communicating with the remote controller.)
15 ( the controller has received a valid message from the host computer,but the response is not being returned
To resolve this problem.
1) Contact the Phone company and have the circuit tested,the circuit has two sets of wires, the transmit portion and the receive portion.
The following describes the circuit.
The remote location (394) this is the transmit portion of the line.
The host location is the receive portion of that line.
If the phone company reports the circuit has been tested and there is nothing wrong,the problem is the hardware.(394)
The (HCP card is defective), this will require a technician to service the controller.
