1.2. Installing the Fax4500D G4 Digital Option

Ensure that the power is turned off and the machine is unplugged.

1. Unfasten the rear cover [A: 4 screws], disconnect the speaker, and remove the cover.

2. Press the front cover release button and open the front cover. Press the scanner release button and lift the scanner cover. Remove the left cover [B: 6 screws], and the NCU [C: 1 screw]. Figure 1.

3. Remove the MBU holder [D: 2 screws]. Figure 2. (The MBU holder will not be reused.)

4. Move the battery jumper on the MBU [E] at location TB1 to off. Figure 2.

5. Remove the MBU from the FCU. Figure 2.

6. Remove the MBU PROM from the socket at location IC 2, and replace it with the G4 Digital Option PROM.

7. Replace the MBU on the FCU, and move the MBU battery jumper to on.

8. Install the grounding plate [F] using one self-tapping screw [F ] and one threaded screw [F ] as shown in Figure 3.

1 2

NOTE: The threaded screw connects to ground.

9. Install the mounting bracket [G] using two self-tapping screws [G , G ]. Figure 3.

1 2

10. Plug the CVG4 Digital board [H] into the FCU and attach it to the bracket [G] using two threaded screws [H , H ]. Figure

1 2

11. Install the NCU [C] and the left cover [B].

12. Remove the hard disk option cover [2 screws], the speaker [1 screw], and the memory card cover [1 screw], if used, from the old rear cover, and install them on the modified rear cover, using the same fasteners.

FAX4500L G4 DIGITAL OPTION

13. Install the modified G4 rear cover from the kit.

14. With the long side of its base oriented horizontally, affix the wire routing fastener above and to the right of the rear screw on the left panel. (The communication cables will be fed down through the routing loop of the fastener away from the paper cassette.)

15. Connect V.35 and RS366 (V.24-200) cables as needed. Figure 4. Thread the cables down through the routing loop. Twist the loop ends together to secure the cables.

Caution: Do not plug in or switch on until everything is connected.

16. Affix the new model label over the old model name on the operation panel.

17. Follow instructions in FAX4500L Field Service Manual for connecting, initializing, and programming the FAX4500L machine. See section 2 to adjust the group 4 internal switches, and parameter switches.

NOT USED IN USA.

05 G4_SN1 : G4 Subscriber Number 1, one of two G4 subscriber numbers.

DO NOT CHANGE THE SETTINGS OF THIS FUNCTION.

ISDN_IP : Integrated Services Digital Network International Prefix. A network access code, similar to the international dial access code, and used to receive transfer result reports when communicating through a terminal adapter to an ISDN network machine.

07 ~ 11 Not used.

18 Not used.

NOT USED IN USA. DO NOT CHANGE THE SETTINGS OF THIS FUNCTION.

DNIC : Data Network Identification Code. A four-digit code which identifies the network the terminal is on, and used when communicating with a machine on another CSDN or PSDN network.

G4_TID : G4 Terminal Identification Code. A three-part code consisting of the network's country code, the terminal's network number, and the terminal name. It is similar to a TTI.

Not used. G4_DMP1 : G4 Memory Dump List.

Prints the commands sent between the FCU and the CVG4 as the contents of a specified range of memory locations G4_DMP2 : G4 Protocol Dump.

Prints a list of protocol signals exchanged during the last communication. See also bit switches ISW12-0 and PSW0E-1.

G4_LIST : G4 System Parameter List. Prints a list showing the current G4 ISW and PSW bitswitch settings, and other parameters programmed with G4 functions
