TIME CODE

ISOLATION & DISTRIBUTION AMPLIFIERS

Since the early ’80s, ESE’s Audio and Video Distribution Ampliﬁers have been recognized for their quality

and durability. Using very similar technology, ESE presents a line of Distribution Ampliﬁers (DAs) capable of

isolating and distributing most any type of Time Code. The basic idea for each model is the same... provide

the ability to distribute time code and compensate for lengthy cable runs while isolating each unit in the

Master Clock System.

Described below are units capable of handling any of the IRIG time codes, ESE Time Code or ASCII time

code. If you’re in need of a DA not mentioned here refer to our DISTRIBUTION AMPLIFIERS Brochure available

on our website or contact the ESE Factory.

ES-243

Quad 1x6 ESE DA (or IRIG-’TTL’)

The ES-243 is designed to accept

any ESE time code signal or any

IRIG time code in its “TTL” form

and output up to 24 identical

copies. The unit has four separate

and isolated channels, each with

six available outputs. Inputs and

outputs are via rear mounted BNC

connectors and each output is

capable of driving up to 4000’ of

cable.

ES-249

1x8 RS-232C/ASCII DA

The ES-249 is designed to accept

RS-232C/ASCII and output up to

eight identical copies. The unit has

a single input and eight outputs

that a r e ac c e s s ible on rear

mounted 9-pin D-subconnectors.

Due to the nature of RS-232C, if long

cable runs are required, it may be

necessary to utilize other time code

that is later translated into RS-232C.

The unit is rack mounted.

ES-242

Quad 1x6 IRIG(AM) DA

The ES-242 is a quad, 6-output

IRIG Time Code DA. Each ampliﬁer

provides a loop-thru input & six 600

ohm outputs. The inputs/outputs are

connected via rear mounted BNC

connectors. The unit distributes IRIG

A, B, E, NASA36, XR3, 2137 & CS3 time

codes it has a transformerless design

that takes a single unbalanced input

and provides six unbalanced single

ended outputs.

ES-210

Quad 1x6 1/5/10 MHz DA

The ES-210 provides four independent

1x6 Frequency DAs in a single

rack-mount enclosure. Each DA

has loop-thru inputs and six isolated

outputs, all accessible via BNC

connectors. Screwdriver-adjustable

Gain controls are provided on the

front of the case. The Gain control

provides an overall signal level

adjustment of -1.6 to +3.4 db. Unused

outputs need not be terminated.

ES-250

1 x 24 RS-232/ASCII DA

The ES-250 is an RS-232C Isolation

and Distribution Ampliﬁer. Three 1 x

8 ampliﬁer circuits allow the incoming

signal to be distributed via the 24

outputs. The unit receives RS-232C

and buffers the signal so that each

of the 24 outputs can drive a single

“user” at a distance of up to 50 feet

(per output). All inputs and outputs

are via rear mounted terminal

block connectors.
