What are the remote connection details for these units?
The remote connector is a 9-way female (socket) ‘D’ type. To remotely divert, connect pin 1 to pin 2. Pin 3 supplies +15V with reference to pin 4. The remotes can act as momentary or latching depending on the setting on the rear panel of the unit:
Pin 1 : Divert switch (Line Connect)
Pin 2 : Common
Pin 3 : Lamp
Pin 4 : Common
What type of remote lamp will the HY-03 drive?
The remote lamp type should be 15V at 40mA max.
What is the power consumption of the HY-03 telephone hybrid?
Less then 6W for HY-03 and HY-03S.
What functions are controlled by the configuration settings switches on the rear panel of the HY-03 telephone hybrid?
SW1 – Dial Tone Disconnect Enable.
SW2 – K-Break Disconnect Enable.
SW3 – Input/Output Mix Enable.
SW4 – Ring Detector (Auto-Answer) Enable.
The telephone hybrids don't automatically disconnect on dial-tone. Why not?
This is correct as there is no dial tone disconnection unless the HY-03DTD dial tone detect option has been added. If the HY-03DTD option has been added and you still have this problem, then ensure that configuration switch SW1 is set to on. Also, ensure that the HY-03DTD option is of the correct type for you network connection. Contact Sonifex for further information.
The telephone hybrid unit keeps "dropping the line". How can I stop this happening?
Firstly, try disabling the k-break function of the hybrid – set the SETTINGS switch SW2 to off. If you still have a problem once the k-break is disconnected, please contact Sonifex technical support technical.support@sonifex.co.uk
The signal input to the HY-03 at the input connector, is audible at the output. Why is this happening?
There is an option on the HY-03 which enables the input signal to be mixed with the output. Ensure the SETTINGS switch SW3 is set to off to disable this option.
Auto answer problem with HY-03 when used on BT Super Highway
The problem is that the HY-03 will not auto answer correctly as it drops the call as soon as it has answered it. After investigation it was found that the BT Super Highway system seems to generate a pulse that looks like a K-break so that the HY-03 would drop the call as soon as it picked it up. The solution is to disable the K-break line disconnect by removing jumper JP4 and enable the line reverse disconnect by putting on jumper JP5, as the BT Super Highway box seems to generate a line reverse signal upon the far end caller hanging up.
