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
Systems Reference Guide (Doc. 6256).
NOTE: Passthrough Mode enables Viewport 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 MP2 or
MP2E). For information pertaining to Passthrough Mode, refer to “Passthrough
Mode” in the Crestron 2-Series Control Systems Reference Guide (Doc. 6256)
System Monitor
The System Monitor allows you to reload firmware into the MP2 & MP2E 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 MP2 or MP2E 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”.
5. Power down the MP2 or MP2E.
6. While powering up the MP2 or MP2E, press and hold Alt+K on the
keyboard until the following text (or similar) appears in Toolbox.
