Serial I/O Multiplexer Installation
4-1
The IBM Multiplexer Set includes the MIM-1 unit, a CMX16-DB or
CMX16-RJ and Power Supply.
CMXs are used when peripheral devices are located more than 200 feet
(61m) from the host computer system or when they are located in a
separate building. The CMX is installed near the peripheral devices and
is connected to the Adapter via a MIM-1. The MIM-1 is usually
installed near the host computer. A CMX is connected to the MIM-1 via
an unshielded two-twisted pair (UTP) link cable. Both DB-25 and RJ-
45 connectors are available in 16-port clusters as shown in Figure 4-1.
