120-OHM TERMINATION JUMPER
The internal jumper places 120 ohms of resistance between Data A and Data B for proper end-of-
line termination. Install the jumper only if the DR4200 Series DigiReader is the last device on the
cable. If you are using:
If you are using the DR4208, DR4226 or DR4238, an external 120 ohm, 1/4 watt resistor must be
used. There is no internal jumper on these models. The jumper is only available on surface mount
technology (SMT) models.
INTERNAL INTERFACE CABLE
An attached cable provides the connection from the printed-circuit assembly and keyboard to the
access control unit wiring on all DigiReaders except for the DR4201, DR4208, DR4226 and the
