Connector Information

3.1 Introduction

This section provides pin assignments and signal descriptions for connectors common to all MMDS systems. For similar information about EM connectors, see the corresponding EM user's manual.

Additionally, this section explains the reset switch, and fuse replacement.

3.2 Reset Switch

RS-232 handshake signals control MMDS resets. A reset initializes the control board from its startup point. If the host serial port does not implement handshaking, you must reset the MMDS manually.

To do so, find the reset switch, which is recessed behind the small hole in the front of the station module. Insert a probe or stiff wire into the reset switch hole. Press gently to trip the switch.

3.3 RS232 Serial Connector

The diagram Figure 3.1 shows pin numbering for the MMDS serial connector. Table 3.1 lists the signals transmitted on the 9-lead serial cable.
