Wiring Diagrams for E&M
Interconnection for E&M Board port connectors vary based on the Speech
Line and Control Line (Type) DIP switch settings configured in Section
4.3.2. Check the port configuration and refer to the appropriate diagrams
below. See Table 4-5 on following page for connector label definitions.
The BV1250 E&M interface using RJ45 type connectors has not
been released at the time of release. When available, cabling
instructions for this model will be provided.
During installation, connectors are aligned upside-down so that the
connections are made 4-3-2-1 rather than 1-2-3-4. Be certain to
check the connector labels for each connection to avoid reversing
the specified order.
