4. Note the three letters eng raved  in the up p er lefthand  c orner of the EIA 
c onnec tor b oard . Data mod ules ship  from the fac tory with b oard  inserted  
with  “ DCE”  in the up p er left c orner. 
5. Use the DCE p osition to c onnec t to DTE eq uip ment.  Use the DTE p osition 
to c onnec t to DCE eq uip ment. To c hang e the mod e, remove the b oard  b y 
grasping it and pulling it gently upward. Flip the board around, left to right,  
and  reinsert it in the soc ket so that the c orrec t op erating  mod e, DCE or 
DTE, ap p ears in the up p er lefthand  c orner. 
6. Snap  the top  c over onto the unit.

To c onfig ure the 7400B d ata mod ule, p roc eed  as follows.
!WARNING:
Elec trostatic  d isc harg e c an severely damag e sensitive elec tronic  c irc uits. 
Before handling  any elec tronic  hard ware, b e sure to wear a g round ing  wrist 
strap  or other static -d issip ating  d evic e. Do not touc h exp osed  c irc uitry or 
semiconductor c hips.
1. If you are not attac hing  a telep hone to the data mod ule, ac tivating data 
metering , or enab ling  b usyout on the loc al loop , you c an use the fac tory 
d efault setting s. The 7400B d ata mod ule is alread y c onfig ured  for your 
use. Stop  now.
2. Otherwise, remove the ac c ess p anel on the top of the c ase b y grasp ing  
the rear lip of the panel and pulling sharply upward.
3. Loc ate the DIP switc h b loc k, a bank of tiny switc hes on the c irc uit board , 
in the c enter of the op ening . 
DIP switc hes 1, 5, and  8 c ontrol the attac hed  telep hone (if any), d ata

!CAUTION:
You must install a 105D or 105C isolating  d ata interfac e ad ap ter when 
c onnec ting d ata mod ules to eq uipment in DC-p owered  c ab inets.
Connec t the d ata mod ule to your house wiring  or DEFINITY as follows.
1. Attac h a D8W c ab le to the LINE
 p ort of the d ata module.
2. If you are g oing  to attac h a telep hone to the data mod ule
a. Attac h a 400B2 ad ap ter to the other end  of the D8W c ab le.
b . Plug  the ad ap ter into a mod ular wall jac k or 103A c onnec tor.
c . Plug  a D7AP c ord  into the 400B2 adap ter.
d. Plug the other end of the D7AP c ord into the auxiliary power supply 
for the telep hone.
You must have a separate p ower sup p ly for the telephone and  for 
the d ata mod ule.
e. Attac h a D8W c ab le to the PHONE
 p ort of the d ata mod ule.
3. If you are not attac hing  a telep hone, attac h the D8W c ab le from the Line 
p ort of the d ata module to a modular wall jac k or 103A c onnec tor.
4. Attac h the d ata-mod ule p ower sup p ly to the p ower c onnec tor on the b ac k 
of the data mod ule, and  p lug the p ower sup p ly into an AC elec tric al outlet.
5. Connec t an RS-232 c ab le to the PORT 1
 c onnec tor on the b ac k of the 
data module. 
6. If the eq uip ment inc lud es a V.35 interfac e, p lug  a V.35 c ab le into the V. 3 5
 
c onnec tor on the d ata mod ule.
7. If the d ata mod ule is a 7400B DCE-only d evic e and  if the other end  of the 
c ab le is c onnec ted  to another DCE d evic e, insert a null-mod em adap ter 
b etween the d ata mod ule and the RS-232 c ab le.
8. Connec t the other end  of the RS-232 c ab le to a serial (COM) p ort 
c onnec tion on the d ata devic e (host c omp uter, serial p rinter, mod em, 
etc .).
