Prepare for callback

If the screen says: “Requesting Session” or “Prepare for Callback”, this simply means that the computer has not yet connected to the panel. (These messages are normal)

CSID mismatch

• Verify the panel and PC CSID.
  • Try setting *36 to 15 15 15 15 15 15 15 15 , then select first time communication.
  • NOTE:  The account number is never checked on direct wire downloading

·        Possibly a bad serial cable

DDE Error While trying to connect.

• This indicates a wiring problem. Check wiring to the 4100SM

Check your wiring for a 9-zone control (Vista-40/50/128B/250BP)

Do not use 4100SM diagram – Refer to each panels installation instructions

NOTE:  Terminal 1 should be closest to the 25 pin connector.

• Screw 8 goes to aux. Power [+] (Panel terminal 6)

·         Screw 7 goes to aux. Power [-](Panel terminal 7)

• Screw 6 Connect the BROWN wire from the 4142TR cable on J8

Terminal 6 is TXD (transmit data) from the panel to the computer.

• Screw 3 Connect the VIOLET wire from the 4142TR cable on J8

Terminal 3 is RXD (receive data) to the panel from the computer.

Check your wiring for a 8-zone control (Vista-100/128FB/32FB/250FB/5140XM)

Do not use 4100SM diagram – Refer to each panels installation instructions

NOTE:  Terminal 1 should be closest to the 25 pin connector.

• Screw 8 goes to aux. Power [+] (Panel terminal 11)
• Screw 7 goes to aux. Power [-] (Panel terminal 12)
• Screw 6 Connect the RED wire from the 4142TR cable on J2

Terminal 6 is TXD (transmit data) from the panel to the computer.

• Screw 3 Connect the VIOLET wire from the 4142TR cable on J2

Terminal 3 is RXD (receive data) to the panel from the computer.

Note: J2 at TOP RIGHT of PCB. Looks like middle on schematic.

Check your wiring for legacy control panels (4140XMP/4120XM)

Screw 8 goes to aux. Power [+]

Screw 7 goes to aux. Power [-]

Screw 6 goes to Data OUT, T7 on the control   

Screw 3 goes to Data IN, T6 on the control

Enable the comm port in Compass

Although you are not using a modem for this communication, you must enable a modem in compass to enable the comm port.  Under modem setup, select the comport you are using, and select any modem from the list (it doesn’t matter which one).

When you enter communications, click [CONNECT]. In the connection window, where it says “INITIATE FROM”, select “DIRECT”. Click the second [CONNECT] button after keying the installer code + # + 5 on the keypad.

Panel must be initiated for download

Enter [Installer Code] + # + 5 at the keypad

Keypad will say “Modem Comm” or “CC”

Test voltages on screw terminals with reference to ground

• 8 = +12VDC (must connect to the panel keypad positive)
• 7 = Ground (must connect to the panel keypad negative)

·         6 = .6-.8VDC then rapidly pulses(4-10VDC) after panel is in “MODEM COMM”.

Ø       If this voltage is not present, check connections to panel.

Ø       This voltage will not be present if the Violet wire is open. Violet must be connected to 4100sm or ground for the panel to have output on the brown/red wire.

• 3 = 1.9-4.4VDC then has one momentary pulse (12 VDC) once when the computer is initiated.  When the computer “Start Communication” or “Connect” has been selected, there should be a pulse on pin 2 of the cable which triggers a pulse on screw terminal 3 of the 4100SM. If the pulse is on pin 2 of the cable, but not on pin 3 of the 4100SM, then either the voltage from the computer is too low or the 4100SM is faulty.

Test voltages from the computer

• With pin 7 on the RS232 cable as ground & measure pins 2 & 3 (one at a time) for a quick pulse after the computer “Start Communication” or “Connect” has been selected.
• Data OUT (pin 2 of the cable) should be –12 then pulse + 12 when the computer is initiated. (Start Communication or Connect)
• Data IN (usually pin 3) will not significantly change. Use a null modem adapter if the pulse is on pin 3.
• If there is no pulse at all, there is possibly a bad or wrong comm port or bad computer cable.

Test the cable

Our Factory Cable is configured:

2à2            3à3            7à7

Other Cables Might Be: (use a null modem adapter with this cable)

2à3            3à2            7à7

A 9 pin adapter should be:

2à2     3à3     7(on 25 pin side) à5(on 9 pin side)
