Functions of Links etc.
JP1
Insert Link for Channel A Active Low Control (JP2 open). Remove both JP1 and
JP2 for an isolated control input.
JP2
Insert Link for Channel A Active High Control (JP1 open). Remove both JP1 and
JP2 for an isolated control input.
JP3
Insert Link in LH position to enable Channel A front panel input changeover control
switch. Insert in RH position to disable.
JP4
Insert Link in LH position for Channel A front panel and external local/remote tallies
to follow Channel A front panel control switch. Insert in RH position for permanent
remote indication. JP4 is intended to be used in conjunction with JP3.
[
Note: JP4 is not shown in the functional block diagrams
]
JP5
Insert link in the position marked REV for the input selection A1/A2 tallies to be
derived from the drive to the signal changeover relay coil. Insert link in the position
marked CON for the A1/A2 tallies to be derived from the front panel or external
control inputs.
JP6
Insert link in the RH position for the common of the A1/A2 selected tally to be earth-
free. Insert link in the LH position for this common to be grounded.
JP7
Insert link in the RH position for the common of the A remote/A local tally to be
earth-free. Insert link in the LH position to ground it.
JP8/JP9/JP10/JP11 Selects Channel A Termination Impedance 50R,75R,600R or Hi Z respectively (Fit
link to one jumper only).
JP12
Insert Link for Remote Switching via GPI port.
JP13
Insert Link for Remote Switching over DART.
JP14
Insert Link for Channel B Active Low Control (JP15 open).
JP15
Insert Link for Channel B Active High Control (JP14 open).
JP16
Insert Link in LH position to enable Channel B front panel input changeover control
switch. Insert in RH position to disable.
JP17
Insert Link in LH position for Channel B front panel and external local/remote tallies
to follow Channel B front panel control switch. Insert in RH position for permanent
remote indication. JP17 is intended to be used in conjunction with JP16.
[
Note: JP17 is not shown in the functional block diagrams

JP18
Insert link in the position marked REV for the input selection B1/B2 tallies to be
derived from the drive to the signal changeover relay coil. Insert link in the position
marked CON for the B1/B2 tallies to be derived from the front panel or external
control inputs.
JP19
Insert link in the RH position for the common of the B1/B2 selected tally to be earth-
free. Insert link in the LH position to ground it.
JP20
Insert link in the RH position for the common of the B remote/B local tally to be
earth-free. Insert link in the LH position for this common to be grounded.
JP21/JP22/JP23
JP24
Selects Channel B Termination Impedance 50R,75R,600R or Hi Z respectively (Fit
link to one jumper only).
JP25
Insert Link for Remote Switching via GPI port.
JP26
Insert Link for Remote Switching over DART.
