TCS2-Tunnelwatch computer (pc) PC37030

The Tunnel Control Station 2 (TCS2) includes a built-in TunnelWatch computer that can be used with TunnelWatch 5 (TW5) and later. This computer has a touchscreen interface that displays the Quick Status screen by default when the computer is on.

Connections

The TCS2 computer has the following connections:

1.          12VDC power to the TCS2 motherboard.

2.        Serial connection from the COM1 DB9 port to the power distribution board located inside the TCS2 power supply assembly.

3.        Two USB extender cables for connecting external USB devices like a flash drive or keyboard.

4.       USB cable to Serial Interface Board.

5.        Two LAN cables to the TCS2 network switch.

6.        HDMI. Not used.

7.        Display Port. Not used.

Replacing

1.          Turn the TCS2 main power switch off. Wait for the PC to shut down and all lights on the power supply assembly to turn off. Note: When the TCS2 main power switch is turned off, the 24VAC, VPS 24VDC, 12VDC, 5VDC, and KPT 12VDC LEDs turn off immediately. The Battery LED will turn on and stay on for 20 seconds, then turn off.

Assigning Static IP Addresses

Note: The first TunnelWatch PC's Ethernet 3 should be set to a static IP address of 192.168.120.90 by default and shouldn't need to be changed. For multiple TunnelWatch PC configurations, such as dual tunnel sites, the second TunnelWatch PC should be set to a different IP address such as 192.168.120.91.

These settings should not to be changed except by a member of DRB Systems Support connected to the TunnelWatch PC remotely.

Troubleshooting

1.          PC not turning on.

a.        Check LEDs on the Power supply assembly. The 12VDC LED should be on.

b.       Check the power connection from the PC to the TCS2 motherboard. Ensure the cable is intact and connected at both ends (PC and Motherboard).

c.        Turn off the TCS2 main power switch. The Battery LED will turn on for 20 seconds then turn off.

d.       Turn on the TCS2 main power switch. The PC should turn on.

i.           The Ethernet switch and PC run on the same 12VDC power. If the Ethernet switch has power, but the PC still will not turn on, the problem is with the panel PC, and it should be replaced.

ii.         If neither the Ethernet switch nor PC will turn on, the power supply assembly should be replaced.

2.        Touchscreen not responding.

a.        Typically, power cycling the panel PC fixes this problem.

b.       Turn off the TCS2 at the main power switch.

c.        Wait until the Battery LED turns off.

d.       Turn on the TCS2 at the main power switch.

3.        TunnelWatch not communicating with the TCS2 Logic card.

a.        Check the Logic Card display.

i.           When properly communicating, the first TCS2 should show a "1" on the display. The second TCS2 should show a "2" on the display, etc.

ii.         If the Logic card is not properly communicating, the display will show blinking "O" or "W".

b.       Verify the address dial settings.

i.           The first TCS2 Logic card address dial should be set to "1", the second TCS2 Logic card address dial should be set to "2", etc.

ii.         If any two Logic cards are set to the same address, it will cause communication issues.

c.        Check the Ethernet cables running from the PC to the TCS2 Ethernet switch.

i.           Two Ethernet cables connect the two Ethernet ports on the PC to the TCS2 Ethernet switch.

ii.         Verify these cables are securely connected at both ends.

iii.       Check the link and activity lights on the TCS2 Ethernet switch ports that the Ethernet cables are connected to. Each port has a green LED and an amber LED. The amber LED should be on steady. The green LED should be on steady, but blink when there is activity on that port.
