MC2E Troubleshooting (Continued)
TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION
System does not
function. Various. Refer to the “System Monitor”
procedure following this table.
Incorrect power supply. Use a Crestron power supply.
IRP2 or serial port not
placed properly. Verify placement of IRP2
(hold phosphor card under
IRP2 while pressing button)
and tighten serial cables.
Used wrong IR/serial
port. Verify that proper IR or serial
port is defined.
A/V system device
does not respond.
Serial cable not wired
correctly. Verify that serial cable is
wired correctly for RS-232,
422 or 485.
Device is not receiving
sufficient power. User the Crestron Power
Calculator to help calculate
how much power is needed
for the system.
NOTE: If communication cannot be established or the control system is locked-up,
refer to “Troubleshooting Communications” in the Crestron 2-Series Control System
Reference Guide (Doc. 6256).
NOTE: Passthrough Mode enables Toolbox access to any serial controlled device
on the network. This aids in troubleshooting by allowing direct communication
between the PC and a network device (effectively “passing through” the MC2E). For
information pertaining to Passthrough Mode, refer to “Passthrough Mode” in the
Crestron 2-Series Control System Reference Guide (Doc. 6256).
System Monitor
The System Monitor allows you to reload firmware into the MC2E in the event that
you cannot load the firmware in the normal mode.
If the system does not function, perform the following procedure:
1. Connect the COMPUTER port on the MC2E to one of the COM ports
(usually COM1) on the PC. Use a straight-through RS-232 cable with a
DB9 male connector on one end and a DB9 female connector on the other.
Most commercially available cables are acceptable; they should have at
least five pins for transmit, receive, ground and hardware handshaking
(pins 2, 3, 5, 7 and 8).
2. Open Toolbox and start the Text Console (click the icon). Then, click
on the Address Book icon in the lower left corner of the window to open
the “Address Book” window.
3. In the “Address Book” window, click the “Add Entry” button and give the
new entry a name (e.g. “System Monitor”).
4. Click the arrow next to the “Device Type” drop down list. A “Warning”
window will open to inform you that this is an advanced feature. Click
Okay, then select “2-Series Control System Monitor” from the drop down
list and click Okay. When you are returned to the “Address Book”
window, make sure to choose RS-232 as the “Connection Type” and the
correct Com port next to “Port”.
