RS-232 Control Cable

Madrigal Audio Labs offers several parts to help communicate via RS-232 to the No320S. The following parts can be order from Madrigal Audio Labs Technical Support.

Part # Description

MRC878 DSUB9 to RJ-11 Adaptor and 2 meter RJ-11 to RJ-11 Cable

MRC808 DUB9 to RJ-11 Adaptor

MLC732 2 meter RJ-11 to RJ-11 Cable

For general purpose and short cable runs to the No320S, Part # MRC878 contains everything needed.

For cable lengths of more then 2 meters - Part # MRC808 and the length of cable needed should be ordered.

RS-232 control units with port types other then DSUB9 will need to have the cable constructed. To construct a cable please follow the example below.

As an example on making the cable we will use the most common connector used, which is a DSUB9. The No320S only needs 3 pins to control the unit via RS-232. As mentioned earlier the No320S’s pin 2 Data Receive must connect to the control devices Transmit. Please read the notes below before constructing the RS-232 cable.

￿Verify Control Devices RS-232 Port Type and Configuration – Refer to Control Device Owners Manual

￿Determine length of cable needed – Check the control device owners manual for length limitations
