Installation
2.1.3 V.24 interface
Connection to the V.24 interface is via the Serial Interface Cable (SIC: S30122-
X5468-X) that is adapted to HiPath HG 1500 using a 6-pin MiniDin socket. The SIC
performs the electrically isolated level conversion from TTL (LAN) to V.24 (PC). The
other side of the SIC consists of a 9-pin SUB-D socket for direct connection to a PC.
Note
A SLIP connection is required for Assistant administration of HiPath HG 1500. How-
ever, a SLIP connection is not possible for the Loader.
2.1.4 Interfaces to the LAN
The physical configuration of the LAN interface is predefined by the IEEE 802
standard. The interface conforms to international standards for electrical safety and
electromagnetic compatibility (EMC). The electrically isolated coupling of the board
at the LAN is performed by the send and receive transmitter. The maximum
transmission speed of this “baseband” transmission technology is 100 MBit/s; the
“Manchester” signaling code is used.
The HiPath HG 1500 boards HXGS and HXGM are provided with a 10/100MB
Autosense LAN port.
