communications are established to the door controllers, check the number of door controllers that are

being reported as communicating on the main transaction screen.

74. Next, you should reconnect any RS-232 sites using the remaining three conversion cables supplied

with the kit to connect the existing RS-232 leads to the RS-232 ports on the new CNC. These are used

in the same way as the host PC conversion cable - they cannot be used to directly connect the new

CNC directly to an RS-232 device, such as a modem.

IMPORTANT

Ensure that the correct RS-232 cables are connected to the correct RS-232 port on the CNC -

the PC administration software uses the RS-232 port number to help identify sites for

communication purposes.

75. Finally, confirm communications with all the RS-232 sites. For sites that communicate via a dial-up

modem, you will need to ‘force dial’ the site first.

6.10 Conversion Cables

Four MKI to MKII CNC conversion cables are supplied with this kit. The wiring of these cables is shown

below for information.

Supplied: Quantity 4, each 2 metres length.

Use 8-core 7/0.2mm2 cable, screened, maximum 6.6ft/2m length.

6.10.1 External Reader

A 6.6ft/2m cable is supplied for connection of a PAC, KeyPAC, and/or Wiegand or Magstripe reader. This

is fitted with an 8-way DIN plug (male) at one end. The other end is flying leads - the color code for the

cable is given in Appendix C - 21512 CNC MKI to MKII Upgrade Kit

6.11 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.

6.11.1 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.
