information about the sites being controlled.

13. Once the CNC has been initialised, you should reconnect the six wire bus cable from the door

controllers (as previously connected to the MKI CNC - no conversion cable is required). Confirm

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

being reported as communicating on the main transaction screen.

14. 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.

15. 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.

2.6 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.

Note

This cable must be screened to comply with emission requirements.

2.7 Using More than One CNC

All administration software allows more than one CNC to be used.

However, if you are using more than one CNC on your system (either PAC Portico for Windows or PAC

Portico Prism) then you should consider distributing these across multiple PCs (workstations) to improve

system performance. Depending on the specifications of the PC, it is recommended that no more then

four CNCs be connected to a single PC.

PAC for Windows

PAC for Windows can support up to 20 ‘masters’ which may be connected to different PCs (when using

the Multi-PC option). A ‘master’ is either a CNC or door controller operating in system type 2 - refer to

15113 PAC 2100/PAC 1100 Installation Guide or 15263 PAC 2200/1200 Series Controller Installation

Guide.

If you are using more than one CNC on your system, you should consider distributing these across

multiple PCs (workstations) to improve system performance.

The total number of sites on a PAC for Windows system, cannot exceed 128 per ‘division’.
