GENERAL DESCRIPTION

The 72-CNV-XX family of converters offer a

flexible and reliable solution to the challenge of

interfacing devices conforming to different serial

communication standards. Grayhill converter

products

environments. All communication lines have

transient protection which other commercially

available converters lack. The converters allow

an RS-232 device (ie. PCs, PLCs, Embedded

Controllers) to communicate reliably over long

distances to multiple devices utilizing the RS-

422/485 standard. Reliability is an inherent benefit

of the differential mode communication of RS-

422/485. Noise introduced onto the RS-422/485

link affects both the positive and negative side

equally, preserving the integrity of the differential

signal between them. Long distances and multiple

slave devices are supported by the converters.

In half-duplex (2-wire) RS-485 mode,

handshaking can be controlled from either end of

the communication link. Typical applications

involve connecting a host computer to remotely

located serial devices such as printers, control

equipment, or data acquisition devices distributed

throughout an office or factory.

The multiple mounting and connector options

allow for many installation possibilities. All three

versions conform to a Eurocard 3U size (160 mm

x 100 mm). 72-CNV-10 will mount in a DIN 41494

card cage. AC power and the RS-422 signals are

brought out to a DIN standard 41612 15-pin

connector (Harting p/n 09061152911 or

equivalent). 72-CNV-11 has standoffs to facilitate

panel mounting. AC power comes in to a screw-

ORDERING INFORMATION

72-CNV-4 and 72-CNV-5 convert serial

communications from RS-232 to RS-485 in

both directions. The converter simply plugs

into any male RS-232 DB-25 connector and

converts the transmit and receive signals to

RS-485 (RS-422) levels at speeds to 115.2

KB. The converters are configured for DTE

(default) or DCE operation.

The 72-CNV-2 is similar to the 72-CNV-4

except that it provides optical isolation and

separate terminal strip or a female DB-9

connector. 72-CNV-12 has a DIN rail card

carrier which permits the assembly to snap on

a DIN rail. AC power and RS-422 signals are

brought in to two screw-type terminal strips. A

female DB-25 connector transfers the RS-232

signals for all three versions.
