Depending on the devices connected to the communications port, it may be
necessary to allow time for transmission. When that is the case, set the trans-
mission delay to regulate the amount of time allowed.
DM 6647: RS-232C port
DM 6652: Peripheral port
Transmission delay (4 digits BCD; unit: 10 ms)
Default: No delay
The transmission delay is set in the PC Setup to create a minimum interval
between sending data from the PC. The transmission delay is used for the fol-
lowing serial communications modes.

munications
No-protocol communications
The delay is not used the first time data is sent from the PC. The delay will
affect other sends only if the normal time for the send comes before the time
set for the transmission delay has expired.
If the delay time has already expired when the next send is ready, the data will
be spent immediately. If the delay time has not expired, the send will be
delayed until the time set for the transmission delay has expired.

Application
Once the PC has sent a response to the host com-
puter, it will not send the next response until the time
set for the transmission delay has expired.
Once the PC has sent data using TXD(48), it will not
send data again until the time set for the transmission
delay has expired.
