Modem

(DB9 DTE)

The MDR2000e used a DB25 Female connector, which was the correct sex for mating with 1990’s era PC COM Ports, but required a special NULL Modem Cable to mate with a modem.
 
The MDR2000e uses a DB9 Female, which is the correct connector for mating directly with a modem (using a standard Male to Female DB9 cable). All MDR2000e-R2’s are also shipped with a DB9 to DB9 NULL Modem cable in case you wish to plug the MDR2000e-R2 directly into a PC COM Port.

The MDR2000e used a DB25 Female connector connection to the PBX serial port.

 

The MDR2000e uses a DB9 Male, for connection to the PBX serial port. Use of a standard off-the-shelf serial cable is all that is required to connect to a PBX.

This is the Ethernet network jack for connection to the local LAN for configuration of the device and retrieval of collected data. The MDR2000e-R2 also provides for the optional collection of IP based SMDR data as well as FTP Push/Pull for retrieval of data, greatly enhancing the usability of the device.
