Rs232 Interface; Troubleshooting And Testing Of The Rs232 Interface; Mcu Control Unit / Circuit Board, Battery - h/p/cosmos 150/50 Operating And Service Manual

Troubleshooting can be supported with the tool of acoustic beeps:
see chapter 5.10 entitled "Optional settings: User Options".
Check OP07 if acoustic heart rate signal is selected.
Option Description
OP07 Activate: Acoustic heart rate signal

9.8 RS232 interface

The most common causes for problems with the RS232 interface are
Wrong connection cable between the running machine and the periphery.
N
Connection to the wrong COM port of the treadmill or the periphery.
N
Another program, running on the external PC, is blocking the COM-port where the treadmill is connected.
N
Technical defects of the connection cable or male/female connector.
N
False setting of protocols/driver at running machine or periphery (ECG, PC, ergospirometry).
N
False setting of COM port at periphery (ECG, PC, ergospirometry).

Troubleshooting and testing of the RS232 interface

Loop-back test: For testing the RS232 of the running machine, a special RS232 test plug including testing
N
instruction is available from the manufacturer. Connect the plug to the RS232 port and adjust OP20: 10
A blinking code will appear, and the instructions will tell you if input and output of the RS232 are working well.
N
PC software h/p/cosmos para control
N
machine. If it works, you know the running machine, the RS232 interface connection cable and the RS232 interface
card of the PC are working well.

9.9 MCU control unit / circuit board, battery

In rare cases, after several years of use, malfunctions of the control unit are possible because of low battery power.
If the incorporated 3V 225mAh CR2032 battery (Lithium type) is low, all settings in the memory will be lost. It is
recommended to replace the battery as a preventive measure every 5 years.
In this case, contact the service department to change the battery of the control unit.
In case of replacement see picture for right positioning of the battery.
The MCU control unit also has a number of status LEDs which can assist in diagnosis.
When communicating with the h/p/cosmos headquarters during error search and
trouble shooting, the authorized technician should observe the indications on these
LEDs and report to the h/p/cosmos headquarters.

OFF: No acoustic heart rate signal
ON: Acoustic heart rate signal for every beat. This function is normally
used to control the regularity of the heart rate or to find reasons for
transmitting problems (such as mobile phones or computer monitors).
