SERIES II INTELLIGENT DATA/FAX MODEMS

Switch #3

Enable/Suppress Responses -- "Q"

(Asynchronous Mode/Dial-Up)

In some Asynchronous mode applications, you may want to suppress all responses from the modem. Place DIP-Switch #3 in the DOWN position to enable Result Code responses (Q0). Place DIP-Switch #3 in the UP position, and answer mode is handled without responses and echo turned off (Q2), but originate is still intelligent.

Enable Responses: Originate/Answer (Q0)	=	Switch #3 DOWN
Suppress Responses: Answer (Q2)	=	Switch #3 UP
Factory Default Setting	=	DOWN

Switch #3

dB Transmission Levels

(Asynchronous/Synchronous Mode/Leased Line)

DIP-Switch #3 adjusts dB transmission levels required by some phone carriers. Place DIP-Switch #3 in the DOWN position to enable -9 dB transmission. Place DIP-Switch #3 in the UP position to enable -15 dB transmission.

-9dB Transmission	=	Switch #3 DOWN
-15dB Transmission	=	Switch #3 UP
Factory Default Setting	=	DOWN

Switch #4

AS/400 Mode

(Synchronous Mode/Leased Line/Dial-Up)

The Series II Modem can function in the IBM AS/400 environment (appearing like an IBM 5853 modem). First, DIP-Switch #7 must be placed in the UP position. This establishes an RTS/CTS condition (state typical for an IBM 5853 modem in half-duplex mode). Next, place DIP-Switch #4 in the DOWN position. This "spoofs" the Modem into operating like an IBM 5853 modem in AS/400 applications. DIP- Switch #4 in the UP position disables this function. Note that the Modem must be in Command mode to allow AS/400 mode (DIP-Switch #8 DOWN); and in Synchronous mode (DIP-Switch #12 UP).
