Match iSeries system parameters for 470x finance controllers

You must match the iSeries™ configuration parameters with the configuration (CPGEN) for the 4701 and 4702 finance controllers. These parameters are described in the following table.

iSeries prompts are listed in alphabetical order by parameter name; the iSeries commands on which the parameters are specified are included in the rightmost column of the table.

For more information about configuring the 4700 controllers, see Volume 6 of the 4700 Finance Communication System Controller Programming Library, GC31-2068.

To configure the iSeries server to a 470x finance controller:

See Example: iSeries server connection to a finance network for an example of connecting an iSeries server to a 4701 finance controller.
Use the following table to connect an iSeries server to a 4701 finance controller.

iSeries Prompt	iSeries Parameter	4700 Macro	4700 Parameter
Connection type	CNN	COMLINK	ACB For SDLC finance communications, if the line is switched (CNN(SWTPP) on the CRTLINSDLC command or SWITCHED(YES) on the CRTCTLFNC command), include the SWM value on the ACB parameter (ACB = SWM).
Exchange identifier	EXCHID	X25CKT	XID The values specified for the 4700 and the iSeries system must match. The block number for the 4700 (first 3 digits of the iSeries EXCHID parameter) must be `057`. The 4700 parameter values are decimal numbers; the iSeries values are hexadecimal.
X.25 link protocol	LINKPCL	X25CKT	LLC For X.25 finance communications, the LLC parameter must specify QLLC for the type of logical link control. LINKPCL(*QLLC) must also be specified on the iSeries CRTCTLFNC command.
Link type	LINKTYPE	COMLINK	TYPE 4700 TYPE parameter must match the LINKTYPE parameter specified on the iSeries CRTCTLFNC command. If LINKTYPE(SDLC), specify TYPE = 4502. If LINKTYPE(X25), specify TYPE = 1424.
Local location address	LOCADR	STATION	ID If the optional LUA parameter is not specified, the value specified for the 4700 ID parameter must match the value specified for the LOCADR parameter on the CRTDEVFNC command. If LUA is specified, the LUA parameter value must match the LOCADR parameter. The 4700 parameter values are decimal numbers; the iSeries values are hexadecimal.
Maximum frame size	MAXFRAME	COMLINK	CNL Value specified for the 4700 CNL parameter must be coordinated with the value specified for the iSeries MAXFRAME parameter on the CRTCTLFNC command. Because the MAXFRAME parameter includes transmission and request header lengths, MAXFRAME should be 9 bytes longer than the 4700 CNL parameter.
Maximum frame size	MAXFRAME	COMLINK	MWL Value specified for the 4700 MWL parameter must be coordinated with the value specified for the iSeries MAXFRAME parameter on the CRTCTLFNC command. Because the MAXFRAME parameter includes transmission and request header lengths, MAXFRAME should be 9 bytes longer than the 4700 MWL parameter. If the iSeries maximum length of request unit (MAXLENRU parameter) specified for device descriptions attached to the 4700 controller is larger than the MAXFRAME parameter specified for the controller description, the 4700 should also specify OPTIONS=(SEGMENT).
NRZI data encoding	NRZI	COMLINK	ACB For SDLC finance communications, if the line does not use NRZI data encoding (NRZI(*NO) on the CRTLINSDLC command), include the DCE value on the ACB parameter (ACB = DCE).
Station address	STNADR	X25CKT	CUA The values specified for the iSeries STNADR parameter on the CRTCTLFNC command must match the physical address (CUA) parameter specified for the 4700.
