2.2 Hardware Link and Switch Settings
The following table refers to Jumper settings shown in the blockdiagramson pages 4 - 7 at the front of this
userguide. Their physical locations are given on the printed circuit board overlayon Page 10.
Functions of Links etc.
JP1 Insert Linkfor Channel A Active LowControl(JP2 open). Remove both JP1 and
JP2 for an isolated control input.
JP2 Insert Linkfor Channel A Active High Control (JP1 open). Remove both JP1 and
JP2 for an isolated control input.
JP3 Insert Linkin LH position to enable Channel Afront panel input changeovercontrol
switch. Insert in RH position to disable.
JP4 Insert Linkin LH position for Channel Afront panel and external local/remote tallies
to follow Channel A front panel control switch. Insert in RH position forpermanent
remote indication. JP4 is intended to be used in conjunction with JP3.
[Note: JP4 isnot shown in the functional blockdiagrams]
JP5 Insert linkin the position marked REV for the input selection A1/A2 tallies to be
derived fromthe drive to the signal changeoverrelaycoil. Insert linkin the position
marked CON forthe A1/A2 talliesto be derived fromthe front panel or external
control inputs.
JP6 Insert linkin the RH position for the common of the A1/A2 selected tallyto be earth-
free. Insert linkin the LH position for thiscommon to be grounded.
JP7 Insert linkin the RH position for the common of the A remote/A local tallyto be
earth-free. Insert linkin the LH position to ground it.
JP8/JP9/JP10/JP11
Selects Channel A Termination Impedance 50R,75R,600R or Hi Z respectively(Fit
linkto one jumper only).
JP12 Insert Linkfor Remote Switching via GPI port.
JP13 Insert Linkfor Remote Switching overDART.
JP14 Insert Linkfor Channel B Active LowControl(JP15 open).
JP15 Insert Linkfor Channel B Active High Control (JP14 open).
JP16 Insert Linkin LH position to enable Channel Bfront panel input changeovercontrol
switch. Insert in RH position to disable.
JP17 Insert Linkin LH position for Channel Bfront panel and external local/remote tallies
to follow Channel B front panel control switch. Insert in RH position forpermanent
remote indication. JP17 isintended to be used in conjunction with JP16.
[Note: JP17 is not shown in the functional blockdiagrams]
JP18 Insert linkin the position marked REV for the input selection B1/B2 tallies to be
derived fromthe drive to the signal changeoverrelaycoil. Insert linkin the position
marked CON forthe B1/B2 talliesto be derived fromthe front panel or external
control inputs.
JP19 Insert linkin the RH position for the common of the B1/B2 selected tallyto be earth-
free. Insert linkin the LH position to ground it.
JP20 Insert linkin the RH position for the common of the B remote/B local tallyto be
earth-free. Insert linkin the LH position forthiscommon to be grounded.
JP21/JP22/JP23
JP24
Selects Channel B Termination Impedance 50R,75R,600R or Hi Z respectively(Fit
linkto one jumper only).
