Introduction

The RS-232C port and peripheral port built into the C200HX/HG/HE PC’s CPU
Unit support the following communications functions:

•

Communications with Programming Devices (e.g., Programming Console or
SSS.)

•

Host Link communications with personal computers and other external de-
vices.

•

RS-232C (no-protocol) communications with personal computers and other
external devices.

•

One-to-one link communications with another PC.

•

NT link communications (one-to-one or one-to-N) with Programmable Termi-
nals (PTs) equipped with an NT link interface.

In addition to these communications functions, optional Communications
Boards that support Protocol Macros can be installed in most C200HX/HG/HE
PCs.

The following table summarizes the communications functions.

Host Link

Host computer or PT

One-to-one
or One-to-N

Provides communications between a
host computer and PC.

The PC’s operating status and the
contents of data areas can be moni-
tored from the host computer.

TXD(––) can be used to transmit data
from the PC’s data areas to the host
computer.

Host Link commands,
TXD(––)

RS-232C
(no protocol)

Host computer or
other RS-232C device

One-to-one

TXD(––) and RXD(––) can be used to
manage simple data transfer se-
quences such as inputs from bar code
readers or outputs to printers.

Control signals RS, CS, ER, and DR
can be controlled by the instructions.

TXD(––), RXD(––)

One-to-one Link

One-to-one

Makes a one-to-one connection be-
tween two PCs using the LR areas of
the PCs.

---

NT Link

One-to-one
or One-to-N

Provides data transfers between the
PC and one or more PTs.

---

Protocol Macro

Other serial device

One-to-one
or One-to-N

The Protocol Macro function allows
the user to define separate data trans-
fer sequences and transfer mes-
sages.

Up to 1,000 communications se-
quences can be registered.

A support program is provided that
simplifies creation of communications
sequences.
