2.5 Jumpers
An explanation of jumper positions is provided here. However, for more detailed information such as loca-
tion, please refer to the UPLC™ Installation Guide that you received with the unit.
2.5.1 Backplane (Rear Panel)
JMP 1/4 – 50 or 75W - Used to select transmitter impedance
JMP 3/5 – 2 or 4 wire - Sets RF coax connection
If set to 2-wire, then the transmitter and receiver are on a common coax (J1), as in most ON/OFF
applications. If set to 4-wire, then the transmitter outputs on coax connector J1 and the receiver
input is on coax connector J2, as in all FSK applications and a few ON/OFF applications.
JMP 2/6/7 – 1 or 2 Power Amplifiers. Set according to the number of power amplifiers present.
2.5.2 I/O Module
INPUT 1
INPUT 2
15V, 48V, 125V or 250V - set according to driving voltage for the given input. If the
INPUT 3
input is not used, it is recommended that the jumper be set for 250V.
INPUT 4
INPUT 5
LL01
LL02
LL03
1.0A/0.1A - set according to load level. Microprocessor relay inputs should be set for 0.1A.
LL04
Greater loads should use the 1.0A setting such as modern lockout relays.
LL05
LL06
LL07
LL08
NO/NC - low level contact outputs set according to desired position when relay coil is de-
LL09
energized. When not energized, the contact will be NO (Normally Open) or NC (Normally
Closed).
LL10
TD01
NO/NC - Trip Duty contact outputs set according to desired position when relay coil is de-
TD02
energized. When not energized the contact will be NO (Normally Open) or NC (Normally
TD03
Closed).
