4.4.1Group ID Settings When Using Allegiant RS-232 or RS-485 Protocol

When using the Allegiant data interface protocol, the Group ID must be set to correspond to a block of 16 physical camera numbers between 1-16 and 481-496. Since each block consists of 16 numbers, the Group ID number for these cameras ranges from 1 to 31. Select a Group ID number that does not duplicate another Group ID number.

A special case exists when multiple units are cascaded using the Interface Unit’s RS-485 data connection (explained later). The left-most Group ID switch on the last unit must be set to 9, to terminate the data link.

For example, if a total of 32 Bilinx-enabled cameras will be connected using the range of Allegiant inputs 17-32 and 49-64, one of the Interface Units must be set to Group ID 002, and the other to 004. If the Interface Unit for cameras 49-64 is the last unit connected at the end of the RS-485 data link, its actual Group ID should be set to 904.

If only one Interface Unit will be connected to support Bilinx cameras on inputs 1 to 16, no change is required from the Interface Unit’s default setting of 901.

Set the Group ID switches using the supplied screwdriver, as follows:

Group ID	Camera	Group ID	Camera
Switches1	Number	Switches1	Number
	Range		Range
001	1 to 16	017	257 to 272
002	17 to 32	018	273 to 288
003	33 to 48	019	289 to 304
004	49 to 64	020	305 to 320
005	65 to 80	021	321 to 336
006	81 to 96	022	337 to 352
007	97 to 112	023	353 to 368
008	113 to 128	024	369 to 384
009	129 to 144	025	385 to 400
010	145 to 160	026	401 to 416
011	161 to 176	027	417 to 432
012	177 to 192	028	433 to 448
013	193 to 208	029	449 to 464
014	209 to 224	030	465 to 480
015	225 to 240	031	481 to 496
016	241 to 256

1The last unit must be set to terminate the RS-485 data line, by setting the left-most Group ID switch to 9.

If the Allegiant’s camera number assignments will be changed (using the Allegiant Master Control Software package) to use logical camera numbers other than the default physical input numbers, Interface Units with Group ID ranging from 1 to 31 are automatically notified of the new settings, by the Allegiant system. This allows the system to support random camera numbers.

NOTE: If the Allegiant’s logical camera number assignments are changed as described above, then downloaded into the Allegiant CPU, the update process may take up to 30 seconds. Camera control functions will not be available until this update has completed.
