DS71-MD4 Serial host and 56k Modem EIA-232 SERIAL CONNECTION The DS-Series host communications modules have an RJ-45 port which uses an 8-pin crossed modular cable to connect to a local EIA-232 device such as a computer terminal or external modem. Most serial computers do not have RJ-45 connections; therefore an adapter is provided with this unit to convert from a DE-9 connector to an RJ-45 connector (Bay Tech Part No. 9FRJ45PC-4). An adapter to convert from a DB-25 connector to an RJ-4

Since the data is clocked across the lines and each device has its own clock, it is possible for the two devices to become slightly out of sync. Therefore, the stop bits not only indicate the end of transmission but also give the computers some room for er

DS71-MD4 Serial host and 56k Modem Disconnect Timeguard This feature ensures reliable binary data transmission by providing a one-second “Timeguard” after the DS-Series receives the attention character. If more data is received within the delay period, the DS treats the character as data, not an attention character; thereby preventing unwanted port disconnection. The Default setting is Disabled.
