Serial Cable
The modem has all its serial port pins enabled. If all the pins are enabled on the attached serial device, it is
important to know whether the device is using DTE or DCE as a communication mode.
The modem is a DCE device, so use a straight-through serial cable between the modem and a DTE device such as
a terminal. Use a NULL modem cable adapter between the modem and a DCE device such as another modem.
If using custom wiring or if some pins are disabled, follow the guidelines below. The wiring will vary depending on
whether the attached serial device is a DTE or DCE.
For specifications on Serial ports, refer to the
Serial Port section
in Chapter 1 of this manual.
Power Source
IMPORTANT
Any installations involving electrical wiring and connections should be done by someone who is experienced in this
field.
As described in the Power specifications and consumption section, the modem can be powered using:
•
4-pin Molex connector for the BT/SN/RAM-6x00 models
•
4-pin screw terminal for the BT/SN/RAM-6x01, BT/SN/RAM-6x01EB and BT/SN/RAM-6x21 models
•
DC 2.5mm round plug for all models
•
PoE (Power over Ethernet) for BT/SN/RAM-6x01EB models
WARNING:
DC 2.5 mm barrel adapter shall not be used in hazardous locations.
Powering up the modem
The modem will power up as soon as an 8 to 30 VDC voltage is applied to one of its power inputs and shuts off
when this input voltage is below 4 VDC.
Testing the power connection
Check the PWR light on the modem: if it is turned on then the modem is powered. If it's off, then review the
installation procedures, or contact Red Lion Technical Support for further assistance.
