Wiegand channel. Valid values include

1,2

(Wiegand channels 1, 2) for all

systems and

3,4

(Wiegand channels 3, 4) for four channel modules. (See

Module Type 0x14 in the

com.wiegand.info

variable description). A

channel value falling out of range should generate an error.

For this system, Wiegand channel

com.wiegand.dealer_code_list

This variable is used to configure a string of dealer codes.

A Dealer Code List can be configured with one or more Dealer Codes, each
separated by a "space". Authenticated secure tags containing a Dealer Code
which matches a value in the Dealer Code List will be forwarded to the
Wiegand interface. Authenticated secure tags containing a Dealer Code that
does not match a value in the Dealer Code List will be blocked. Dealer Code
filtering does not apply to legacy tags. Dealer Code filtering can be disabled
by specifying a blank Dealer Code List.
