CP-118EL

The CP-118EL board has a female SCSI VHDCI68 connector on the board, with various

connection options available for connecting from the board to your serial devices. In this chapter,

we provide pin assignments for the board side connector, as well as pin assignments for device

side connectors for the different connection options.

The CP-118EL board supports RS-232, RS-422, 4-wire RS-485, and 2-wire RS-485. Note that the

RS-422 standard uses a balanced voltage digital interface to allow 9600 bps communication over

cables of up to 4000 feet in length. You can connect ten receivers to one driver for broadcasting

systems. The RS-485 standard is an enhanced version of the RS-422 balanced line standard. It

allows multiple drivers and receivers to work on a multidrop network. A maximum of 32 drivers

and 32 receivers can be set up on a multidrop network. The CP-118EL board supports both 2-wire

half-duplex and 4-wire full-duplex RS-485 communications. In 2-wire RS-485, Data+/- pins are

used for both data transmitting and receiving.
