CDM-600L DC Modem Installation: The DC input CDM-600L is connected to a nominal 48 VDC prime power source. The DC input is isolated from the chassis and from the DC output to the BUC if equipped with internal BUC power supply. The chassis may be connected to a local system ground using a separate wire to the ground stud on the back of the chassis. Since the DC input is isolated, either the positive or the negative side of the DC input may be common with local ground. Labeling on the back of the chassis indicates the positive and negative terminals of the input power socket.
The modem is supplied with a 2-wire power cable (CEFD part number CA/WR10327-1) with one end terminated with a connector that mates with the modem input power socket. Positive DC input is on the red wire, while negative DC input is on the black wire. The DC input connector is Molex PN 03-12-1026 with Molex PN 08-12-1222 pins.

Introduction |
MN/CDM600L.IOM |
EDMAC Note: In EDMAC mode, an additional 5% overhead is combined with the traffic data (1.5% in Turbo BPSK modes, Turbo Rate 1/2 QPSK/OQPSK, and all data rates greater than 2 Mbps), which permits Monitor & Control (M&C) information to be added transparently to the user, allowing access to the distant-end modem. This mode does not require any additional cabling at either the local or distant-end modems; access to EDMAC is via the standard M&C control port.
Full M&C is possible and, importantly, the on/off status of the carrier at the distant-end carrier can be controlled. In addition, as of Firmware Ver. 1.2.0 (CDM-600L) or 1.5.0 (CDM-600) and higher, the proprietary D&I++ framing mode is available. This combines Drop & Insert (D&I) operation with a similar EDMAC link and a 2.2% overhead.
CDM-600/600L Common Features
•Compliance with IESS-308 / -309/ -310 / -315 specifications, with significant features added in Closed Network modes.
•Variable data rates from 2.4 kbps to 20 Mbps, in BPSK, QPSK, Offset QPSK, 8-PSK, 8-QAM, and 16-QAM modes are offered.
