Chapter 2 - Installation

The sixteen DIP-Switches and two berg jumpers control various modem options or set default values for the MT2834 Command mode. There is a difference in how several of the switches operate depending on whether you are in synchronous or asynchronous mode (DIP-Switch #12).

Most communications software packages have installation procedures of their own, which call for certain modem DIP-Switch settings. If you are using a package other than MultiExpress, follow the software's instructions.

2.3.1DIP-Switch Settings

The vast majority of installations are similar, with the MT2834 being used to dial up a remote installation where the call is automatically answered. The factory default DIP-Switch settings are based on this assumption. The following is a brief description and summary of the MT2834's DIP-Switch options:

Switch	Function	Position	Effect
#1	DTR Forced/	UP*	DTR forced from
	DTR from Interface *	DOWN	computer/terminal
#2	Flow Control &E4*	UP*	Hardware flow
	(Async/Dial-Up/Leased Line)	DOWN	control enabled
#2	SDLC*/BSC (Sync)	UP*	SDLC enabled
		DOWN
#3	Result Codes Enabled*	UP	Modem responses
	(Async Dial-up)	DOWN*	are echoed
#3	DbM Transmit -15dB/-11dB*	UP	Lease Line
	(Async/Sync/Leased Line)	DOWN*	transmits at -11dB
#4	UUCP Disabled* (Async	UP*	UUCP
	Dial-Up/Leased Line)	DOWN	"spoofing" Disabled
#4	AS/400 Mode Disabled*	UP*	AS/400 Mode
	(Sync Dial-Up/Leased Line)	DOWN	Disabled
#5	Auto-Answer Enabled*	UP*	Auto-Answer
	Async/Sync/Dial-Up)	DOWN	in dial-up mode

*Factory default setting.
