trolled by the Data Set Ready (DSR) signal which is always active. Crossing of

the Receive Data and Transmit Data signals must also be performed.

This cable is also useful when connecting an LDM-1 to any DTE that does

not assert an RTS signal. However, its application is limited to point-to-point

network segments.

TEST SOFTWARE

CTSCU.exe is a DOS application designed to test the operation of LCUs and

LDM-1s. CTSCU.exe can be used to quantify bit error rates over point-to-

point and multi-drop networks. This section describes in detail how to use the

CTSCU.exe software to perform a typical communication test.

EQUIREMENTS

To run the CTSCU.exe test software the following items are required:

• A Windows 3.X PC with the CTSCU.exe software installed.

• One or more LCUs installed with the TxDOT provided TMS Version 2.2

EEPROM.

• One master LDM-1 that will be connected to the PC running CTSCU.exe.

• One slave LDM-1 for each LCU.

• A two-pair cable connecting the LDM-1s in either a point-to-point or multi-

drop network configuration.

• One 9-pin (female) to 25-pin (male) serial communications cable to be con-

nected between the master LDM-1 and the comm. port of the PC.

• A DB-25 (male) to DB-25 (male) cable, wired one-to-one, that will connect

each slave LDM-1 to each LCU.

NSTALLATION

With power off to all of the equipment items, do the following:

WARNING: CTSCU.exe runs best with 3.X versions of Windows. It will not

run properly in a Windows XP environment. It frequently has performance

problems running under Windows 98.
