4.6 External Reader
MKII
Only
A third party Wiegand reader and PAC reader, Wiegand reader and KeyPAC reader, or a Wiegand
reader and Magstripe reader (devices encoded ISO track 2) may be connected to the external reader
socket on the rear of the CNC. This does not affect the use of the in-built reader which may be a PAC or
KeyPAC reader.
Non-PAC ID devices can be used on the CNC without the need for a PC Interface Kit. A Wiegand or other
interface unit is not required.
A flying lead, supplied with the CNC is used to connect to the DIN socket on the rear of the CNC. The
connection information is detailed in Appendix C - 21512 CNC MKI to MKII Upgrade Kit
4.7 Description
This kit allows you to upgrade an existing CNC-based installation to use the improved features and
performance of the new CNC, with the minimum of effort and time involved in performing the upgrade.
4.7.1 Contents of the Kit
The kit consists of a MKII CNC (the power supply is not supplied with this kit - the existing power supply
should be used) and four cables. These cables should be used to connect the cables that currently
connect to the host PC and RS-232 ports of the existing MKI CNC to the new MKII CNC.
Note
Do not attempt to use these cables to connect the MKII CNC directly to the host PC, modem, or
other RS-232 device - they will not work. They are ‘conversion’ cables.
4.8 Installation
31. Ensure the PC administration software is running and the CNC display is showing:
** MONITORING **
If any updates are displayed for sites, you should make sure they are sent to the door controllers on
those sites first - for sites that communicate via a dial-up modem, you may need to ‘force dial’ the site
first.
32. Make sure that all the connectors currently plugged into the rear of the CNC are labelled and easily
identified.
33. Make sure the On-Line Transaction display is visible and transactions are being displayed.
34. Disconnect the connectors from RS-232 ports 1 to 3 and the six wire bus on the rear of the CNC.
35. When no further transactions are being displayed by the PC administration software, log in to the PC
administration software using the supervisor key/card.
36. Disconnect the host PC and power supply connectors from the rear of the CNC.
37. Ensure the switches on the underside of the MKII CNC are correctly set, see Section 2.2.1. Particular
attention should be made to switch 7 - Host PC to CNC Baud Rate which is dependent on the
administration system being used.
38. Replace the MKI CNC with the MKII CNC.
39. Connect the cable from the power supply to the power supply connector on the MKII CNC. A
sequence of messages should be displayed - as described in Section 3.5.1.
40. Using one of the conversion cables supplied, connect the 9-way D-type connector to the host PC port
on the new CNC and the 25-way D-type connector to the existing CNC to PC cable.
Note
Do not attempt to use this cable to connect the new CNC directly to administration PC - it will not
communicate. It must be used in conjunction with the MKI CNC to PC cable.
41. Verify the PC to CNC communications status.
42. Initialise the CNC - this process will clear the contents of the CNC memory and send to the CNC
information about the sites being controlled.
