3-4

Jumpers

JP 3

JP 4

To set the pull high/low resistors to 150 KΩ, leave jumpers JP3 and JP4 open (not shorted). This

is the default setting.

To set the pull high/low resistors to 1 KΩ, short jumpers JP3 and JP4 with jumper caps.

ATTENTION

Do not use the 1 KΩ pull high/low setting on the MGate MB3000 when using the RS-232 interface.

Doing so will degrade the RS-232 signals and reduce the effective communication distance.
