CP-118EL-A
The CP-118EL-A 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-A 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-A 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.
