43. 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.

44. 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.

45. 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.

4.9 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.

Appendix D - Cable Descriptions. The built-in reader can be used in conjunction with a Magstripe or

Wiegand reader connected to the external reader port.

Notes

1. If the external reader is a PAC, KeyPAC, Wiegand, or Magstripe reader, switch 4 must be set ON.

2. The universal Wiegand option allows any card to produce a token code. This option is enabled by

default. Any card greater than 16 bits will produce a token code.

The formats of Wiegand and Magstripe readers supported are listed in Section 2.3.5.

4.10 Six Wire Bus

The six wire bus is PAC Portico's proprietary communications link for local connection of door controllers.

It uses up to 3000ft/1000m of standard unscreened signal cable to connect door controllers. No single

length of cable should be longer than 1500ft/500m.

4.10.1 Cable Specification

Use multi-stranded, unscreened, 6-core, 22AWG/0.355mm² alarm or signal cable.

The cable can be arranged as shown below as long as the total amount of cable does not exceed

3000ft/1000m, and no single length is longer than 1500ft/500m.

If you do use screened cable, you should reduce the maximum distance allowed to 1100ft/350m total,

490ft/150m between devices on the bus.
