Hardware Reference Guide 115C ONFIGURING ANTENNAScable. Connect one end of the cable to the console port on the HiveManager and the other end to theserial (or COM) port on your management system. The management system must have a VT100 terminalemulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal ® (providedwith Windows® operating systems).Figure 5 DB9 Console port pin assignmentsThese pin assignments show a DTE configuration for a DB9 connector complying with the RS-232 standard.Because this is a console port, only pins 2, 3, and 5 need be used.C ONFIGURING ANTENNASAs anyone who has administered a WLAN system knows, configuring the antennas correctly at the outsetcan save you lots of trouble. The external antennas on many Aerohive devices are adjustable, and can bepatch, directional (single-direction), and omnidirectional antennas. The type of antenna you use determinesthe coverage pattern.Single-direction AntennasThe most common external antennas are directional patch antennas that provide coverage in a singledirection. Most commonly they have a transmission pattern similar to that shown in Figure 6 on page 116.Based on the gain, the signal will be wide (like the low gain antenna shown on top) or narrow and long (likethe high gain antenna shown on the bottom).Aerohive devices accommodate external antennas via coaxial jacks on the chassis . These jacks arestandard male RP-SMA connectors.Coverage patterns are not perfect for these antennas and they often broadcast slightly indirections other than the primary one. These extra "lobes" can be seen in both of the patternsshown below.1 2 3 4 56 7 8 9Male DB9 Console portView of the consoleport on HiveManagerPin Signal Direction1 DCD (Data Carrier Detect) (unused)2 RXD (Received Data) Input3 TXD (Transmitted Data) Output4 DTR (Data Terminal Ready) (unused)5 Ground Ground6 DSR (Data Set Ready) (unused)7 RTS (Request to Send) (unused)8 CTS (Clear to Send) (unused)9 RI (Ring Indicator) (unused)RS-232 Standard Pin Assignments |
