Note: A Normally closed state implies the state when power is applied to the relay 
in a normal operating state, without a trigger or alarm condition present. 

 

The DCE DB-9 female connector is intended for low-speed data: 7 bits, even parity, 1 
stop bit, up to 38.4 kbps (default). These outputs are user-configurable via the Setup 
Menu on the front panel. 

The interconnect cable from the D9859 transcoder to a PC should be straight through 
(for example, no handshaking), shielded and equipped with a DB-9 male connector 
at one end to mate with the rear panel RS-232 Data interface, and a female DB-9 
connector to connect to the PC.

The D9859 transcoder is equipped with a connector labeled Cue Tone/Relay for 
alarm relay outputs for remote alarm signaling. This connector provides Cue Tone, 
Cue Trigger and Alarm relay functionality. These outputs are user-configurable via 
the Setup Menu on the front panel. 

The connector is a 15-pin sub-D female connector. The following diagram shows the 
connector and the pin allocation table for Cue Tone, Cue Trigger and Alarm relay 
connections.
