3.1. Hardware

Connection Tips / Hints

The following notes are provided from a TGM manual:

The TGM code constantly checks the status of the DSR input of its serial ports connected to
the DTR output of the remote serial ports. If the TGM DSR is NOT ASSERTED (FALSE),
then the TGM software will suspend serial data output out of TGM Tx, and start a timeout
timer (the default timeout time = 30 seconds as set in CONFIG.DAT). During this timeout, if
the DSR is ASSERTED (TRUE), then the TGM software will begin transmitting data. If the
DSR hold exceeds the (configurable) 30 second timeout, the TGM will report a malfunction:

MALFUN

PRINTER

OFF

LINE

hh:mm

dd

mmm

yy

MALFUN

REMOTE

OFF

LINE

hh:mm

dd

mmm

yy

depending upon which port has timed out. Restoration of the DSR status as ASSERTED or
TRUE will clear the above malfunction(s). The above malfunctions will occur if the active
TGM serial ports (printer or remote) are not connected upon bootup with the proper null
modem cables to active serial ports with DTR (connected to theTGM DSR)
ASSERTED/TRUE. The TGM can have the hardware control defeated by jumpering CTS to
DTR to DSR on the TGM side of the connector.

The driver does not provide the hardware handshaking required and assumes the hardware
control has been defeated with jumpers.
