Connect Systems Inc. - Model 9800 Page 9
JUMPER STRAP OPTIONS
JP-1 Factory Installed. Cut only if the Electronic Voice Delay
(Option 9801) is installed. (JP-1 is near U18)
JP-2 Factory installed. Should only be cut if any signaling option
has been installed. (JP-2 is near U7)
JP-3 Audio output range strap. Strap in = low level (0-1 V). Strap
cut = high level (0-5 V). Strap factory installed. (JP-3 is near
U5)
JP-4 Factory installed. Should only be cut if CTCSS option TSU-32P
is installed. (JP-4 is near C9)
JP-5 Factory installed. Removal eliminates the built-in de-emphasis
network. Cut only if receiver audio is taken past de-emphasis.
(e.g. from the volume control). (JP-5 near C36)
JP-6 This strap should not be connected if Audio In has been
connected to the FM detector. Strapping JP-6 enables COS
operation and selects the required COS polarity. If the selected
COS takeoff point goes high when a signal is received, connect
the center pad to the + pad. If the COS input goes low when a
signal is received, connect the center pad to the - pad. When
P11 (COS threshold) is properly adjusted, the noise LED will be
illuminated when there's no signal, and go out when a signal is
received.
Note: A plastic push-on connector will be found on the center
pin. Simply remove and re-install over the two desired pins.
JP-7 Selects whether the Aux. Relay output is normally open (NO) or,
normally closed (NC). JP-7 is factory strapped for NO. For NC
operation, connect the center pad to the NC pad. It may be
necessary to remove the rear panel to make this modification.
(JP-7 is near the Aux. Relay K2).
JP-8 JP-8 is not used and does not exist on the board.
JP-9 JP-9 and JP-10 are used to enable / disable line in use
& detection. These straps are mutually exclusive. That is to say
JP10 that one and only one must be strapped. The 9800 is delivered
with line in use detection disabled (JP-9 strapped). To enable
line in use detection remove the plastic push-on clip from JP-9
and re-install on JP-10.
AUSTEL VERSION: The Australia version does not have line in use
detection, therefore there is no JP-9 and JP-10. There is a permanent
strap in the JP-9 position.
