J12, J13 Jumpers
Installing a burg jumper on J12 will place in service a 112 ohm line-to-line terminator across the receiver
line (RXD, RXD RTN). If the system is subject to extremely noisy environments, it would be better to
terminate only the receiver side of the communication line by line-to-ground termination on each side of
the receiver line (RXC, RXD RTN). Installing burg jumpers on both J12 and J13 will terminate each side
of the receiver line through 56 ohm to ground.
6.7
J14, J15 Jumpers
Installing a burg jumper on J14 will place in service a 112 ohm line-to-line terminator across the receiver
line (TXC, TXC RTN). Installing burg jumpers on both J14 and J15 will terminate each side of the
transmitter line through 56 ohm to ground.
