Overview 2
Overview
The Comtrol P60 RS-232 Surge Protector protects the RS-232 communication line from TOV (Transient Over Voltages) which comes
from lightning, electrostatic discharge, and other forms. TOV is always a major factor that damages components and makes ports
unreliable. To provide a solution for this problem, Comtrol includes a Transient Voltage Suppressor to our I/O ports to clamp surge
voltage to protect ports from TOV.
Specifications
The following list illustrates the P60 conditions and specifications.

User Manual
Installation
1. Connect the cables using the labels for a guide.
The labels, local and remote, are on the top surface of the P60. The P60 blocks a surge from both the local and the remote site, but
the LED indicators and the local host are protected only if the surge comes in from the remote port. We recommend that you keep the
P60 as close as possible to the local host. Otherwise you may risk damaging the P60 as well as the local host if a surge occurs between
the P60’s local port and the host.
If you are using the terminal block, note that the remote port and the terminal block are the same except that the DCD signal in not
available in the terminal block.
If you need to protect both local and remote hosts, you will need to install two P60s.
2. We recommend that you connect the GND at the terminal block to the earth ground to provide a ground path to prevent electrical
shock caused by lightning.
You should do this if you are using either the RJ45 connection or the terminal block. If possible, use the same ground that you use
on the device that you want to protect.
Caution
Earth Ground must be made in order to ensure product performance.

LED Indicators
The LEDs on the top indicate connections for TxD, RxD, DTR, DSR, RTS, CTS, and DCD. They are dim when there is not a signal.
TxD Indicator (signal from the local port)
Green: connected but not transmitting data.
Orange: transmitting data from local to remote site.
RxD Indicator (signal from the remote port)
Green: connected but not receiving data.
Orange: receiving data from the remote to local site.
DTR/RTS Indicators (signal from the local port)
Red: connected and DTR (or RTS) signal is turned on.
Green: connected and DTR (or RTS) signal is turned off.
DSR/CTS/DCD Indicators (signal from the remote port)
Red: connected and DSR (or CTS/DCD) signal is turned on.
Green: connected and DSR (or CTS/DCD) signal is turned off.
Self Test
This configuration is for a P60 self test. Run the terminal emulation program to see if what you typed is what you received.
In the previous image, all the signal lines could be either from the remote site RJ45 or the terminal block and shorted as shown.

Cable Wiring 6
Cable Wiring
There are two types of RS-232 cable wiring which are listed as follows.
Note: 1. The Terminal Block does not support a DCD signal.
2. DTE: Data Terminal Equipment or “your PC”) or DCE (Data Communications Equipment or “remote device.” Check the
precise DTE/DCE pinouts. For an example, see the following DTE/DCE pinout examples.
