1. Introduction
1.1 PXI-93518 Overview
1.1.1 What is the PXI-93518
PXI-93518 is an eight ports serial communication module, compatible with RS-422,
RS-485 and RS-232 standards, with fast transient voltage suppression protection
circuit. This protector can effectively suppress lightning and ESD, provide 600W
lightning surge protection power for each line, as well as surge voltage and transient
overvoltage generated on the line for various reasons, and the very small inter pole
capacitance ensures the high-speed transmission of RS-422 / RS-485 / RS-232
interface.
1.1.2 PXI-93518 Features
Eight RS-422 / 485 / 232 communication ports
Baudrate, data bit length, stop bit length (1 or 2 stop bits) and parity mode can
be set
Baud rate:
1. RS-422 and RS-485 support up to 921.6k bps;
2. RS-232 supports up to 115,200 bps.
Receiving circuit with pull-down resistor
Standard serial port operation mode
All ports adopt photoelectric isolation and ± 15kV surge protection
120Ω terminal resistance matching
Operation System Compatibility: Windows 7/ 10
Operating temperature: -40℃～+85℃
Relative Humidity: 0～90%

2. Installation
This chapter describes the configurations of the serial communication module. The
contents in the package and unpacking information that the user should be aware of
are described in the beginning.

PXI-93518 | jytek.com | 6
2.1 What You Have
In addition to this User's Manual, the package includes the following items:
PXI-93518 Serial Communication Interface Module
DB62 Connector
2.2 Unpacking
Your serial communication module contains sensitive electronic components that
can be easily damaged by static electricity.
The module should be done on a grounded anti-static mat. The operator should be
wearing an anti-static wristband, grounded at the same point as the anti-static mat.
Inspect the module carton for obvious damage. Shipping and handling may cause
damage to your module. Ensure there are no shipping and handling damages on the
module before processing.
After opening the module carton, remove the system module and place it only on a
grounded anti-static surface component side up.
Again inspect the module for damage. Press down on all socket IC's to ensure they
are properly seated. Do this only with the module placed on a firm flat surface.
Note: DO NOT APPLY POWER TO THE MODULE IF IT HAS BEEN DAMAGED.
You are now ready to install your PXI Module.
2.3 Installation Procedure
1. Turn off your PXI computer system.
2. Turn off all accessories (printer, modem, monitor, etc.) connected to computer.
3. Select a PXI slot.
4. Before handling the serial communication module, discharge any static buildup on
your body by touching the metal case of the computer. Hold the edge and do not
touch the components.
5. Position the module into the PXI slot selected.

6. Secure the module in place of the system.
2.4 Hardware Configuration
The serial communication module has Plug and Play component, the card can
requests memory usage (I/O port locations) of the card which is assigned by
system BIOS. The address assignment is done on a board-by-board basis for all serial
communication cards in the system.
2.5 Software Installation
2.5.1 Windows 7 Installation
