Section 2: PCB Installation and StartupAspila EX Hardware Manual Section 2: PCB Installation and Startup 2-172Digital Station (8/16ESIU) PCB (Figure 2-8)The ESIU PCB provides:• 8 (8ESIU) or 16 (16ESIU) digital extension circuits (used for digital telephones, DSS consoles,1SLTAD adapters, 2PGDAD adapters)• 2 (8ESIU) or 4 (16ESIU) extension status LEDs (each LED indicates status for 4 extensions -BL1 used for ports 1-4, BL2 for ports 5-8, BL3 for ports 9-12, and BL4 for ports 13-16).• 1 PCB status LED• 1 run/block switchThe CN102, CN103, CN202, and CN203 connectors each provide connection to 4 digital station ports.With the 8ESIU PCB the CN202 and CN203 connectors and the BL3 and BL4 LEDS are removedfrom the PCB.In order to program the system with a multibutton telephone, an 8ESIU or 16ESIU PCB should beinstalled. However, system programming can be done using the PCPro or WebPro applications orthrough a VoIP telephone. The ESIU requires one universal slot, with a maximum of 16 PCB’s per sys-tem.The ESIU connections are not polarity sensitive to the digital extensions.Connector Pin-Outs on ESIURJ61 Cable Connector - CN102, CN103, CN202, CN203Pin No. Connection1 port 42 port 33 port 24 port 15 port 16 port 27 port 38 port 4CÔNG TY VIỄN THÔNG VIỆT PROChuyên phân phối tổng đài NEChttp://vietpro.com.vn
