Troubleshooting a Matrix 3200/6400 System Problem
All Matrix 3200/6400 BME front panels include LEDs at the bottom of the panel which are bracketed and labeled DIAGNOSTICS. These LEDs (Figure

If a BME fails to power ON, check the BME external AC fuse (see Page
BME #0 must be powered ON at the same time or after other BMEs. Any BME powered on after BME #0 will not be seen by the internal system software.
Communications
RS232 TX - Red LED ON/Blinking = BME is transmitting data to Host
RS232 RX - Green LED ON/Blinking = BME is receiving data from Host
BME TX - Red LED ON/Blinking = BME is transmitting data
BME RX - Green LED ON/Blinking = BME is receiving data
MKP TX - Red LED ON/Blinking = BME is transmitting to Remote keypad
MKP RX - Green LED ON/Blinking = BME is receiving from Remote keypad
1. MKP TX/RX LEDs are not present on SYNC BMEs.
2.MKP LED conditions above apply only to BME #0.
3.
4.A communications failure between BME #0 and other BMEs could be caused by one BME loading down the BME TX or RX line. To determine if that is the case, run the
System Status
Amber LED | ON = Normal |
| OFF = System failure - Call Extron Tech Support |
